C1911 – Tire ID reception failed – tire 1 (Mitsubishi)

Mitsubishi-specific code — factory diagnostic data

Last updated: March 30, 2026

Definition source: Mitsubishi factory description · Autel MaxiSys Ultra & EV. Diagnostic guidance is based on factory-defined fault logic for this code.

C1911 means the tire pressure system cannot “hear” one wheel’s sensor ID, so the TPMS warning may stay on or flash. Most owners notice a warning light and no pressure reading for one tire position. According to Mitsubishi factory diagnostic data, this code indicates “Tire ID reception failed – tire 1.” That description points to a communication and identification problem, not a confirmed bad sensor. The module expects a specific transmitter ID. When it stops receiving that ID for long enough, it stores C1911 and may disable display updates for that tire.

C1911 Quick Answer

C1911 on a 2016 Mitsubishi Outlander means the TPMS control module failed to receive the registered tire sensor ID for “tire 1.” Fix it by confirming the missing ID with scan data, then verifying sensor registration, RF reception, and related power/ground and antenna paths before replacing any parts.

What Does C1911 Mean?

Official definition: “Tire ID reception failed – tire 1.” In practice, the Outlander’s TPMS cannot identify one registered tire pressure sensor, so it may not report pressure for that tire and it will command a TPMS warning.

What the module actually checks: the TPMS logic compares received RF transmissions against stored sensor IDs. It also checks timing and message validity. Why that matters: C1911 points to a suspected trouble area in ID reception. It does not prove a failed sensor. A dead sensor, wrong ID registration, RF interference, or a receiver issue can all produce the same “ID reception failed” result.

Theory of Operation

Under normal operation, each wheel-mounted TPMS sensor broadcasts its unique ID with pressure and temperature data. The Mitsubishi TPMS receiver and its control logic accept the message only when the ID matches a learned or registered value. The module then updates scan data and the warning logic.

C1911 sets when the module does not receive the expected ID for the tire position Mitsubishi labels as “tire 1.” The breakdown can come from the transmitter side, the registration side, or the receiver side. A sensor that transmits a different ID than the module expects will look the same as “no signal.” The diagnostic approach must confirm which condition exists before any parts decisions.

Symptoms

Drivers and technicians usually notice one or more of these symptoms with C1911.

• TPMS light illuminated or flashing, often returning soon after a reset
• Missing reading for one tire position in the dash display or scan data
• Warning message related to tire pressure monitoring, depending on cluster configuration
• Intermittent operation where the same tire appears, then disappears during driving
• No successful relearn or registration completes but the ID still shows “not received”
• Recent wheel work after rotation, tire replacement, or sensor service
• Multiple TPMS codes if additional IDs also drop out under the same conditions

Common Causes

• TPMS sensor not programmed to the vehicle: The TPMS ECU will not accept a sensor ID it does not have registered, so it reports an ID reception failure for tire 1.
• Wrong sensor type or incompatible frequency: An incorrect Mitsubishi-compatible sensor may transmit a format the receiver cannot decode, which blocks ID validation.
• Weak TPMS sensor battery: Low sensor output reduces signal strength and creates intermittent or missing ID reception events.
• RF interference or shielding near the wheel: Aftermarket electronics, certain wheel designs, or heavy tinting/film near antennas can attenuate the signal and prevent reliable ID capture.
• Receiver/antenna circuit fault (open, short, or high resistance): A damaged antenna lead or connector increases loss, so the TPMS ECU cannot receive the tire’s ID consistently.
• Poor TPMS ECU power or ground under load: Voltage drop at the module can reduce receiver sensitivity and cause missed ID reception even when the sensor transmits normally.
• Harness damage at wheel well or underbody routing: Road debris, corrosion, or prior body work can damage wiring and create intermittent reception faults.
• Related network or module communication issue: If the TPMS ECU has unstable communication or resets, it may log an ID reception failure during the outage.

Diagnosis Steps

Tools you need: a scan tool that can access Mitsubishi TPMS data and perform ID registration, plus a TPMS activation tool if the platform supports it. Use a quality DMM for voltage-drop testing under load. A wiring diagram helps identify TPMS ECU power, ground, and any receiver/antenna circuits used on the 2016 Outlander platform.

1. Confirm C1911 on a full vehicle scan. Record stored, pending, and history codes. Save freeze frame data, focusing on ignition state, battery voltage, vehicle speed, and any related chassis/body codes. Freeze frame shows the conditions when the DTC set. Use scan tool snapshot later to catch an intermittent drop during a road test.
2. Check whether the TPMS module appears on the scan tool network list. If the scan tool cannot communicate with the TPMS ECU, diagnose that first. Next, inspect the simplest items before meter work: verify all four tires have TPMS sensors installed, confirm correct wheel set, and check for aftermarket devices near the dash or wheel wells that can affect RF reception.
3. Check fuses and power distribution that feed the TPMS ECU. Do this before probing ECU pins. Inspect for loose fuse fit, heat damage, and signs of water intrusion in junction blocks.
4. Verify TPMS ECU power and ground with a voltage-drop test under load. Keep the circuit operating while you test. Aim for less than 0.1 V drop on the ground path with the module powered. Also check the power feed drop from the fuse output to the module. Do not rely on continuity checks alone.
5. Use the scan tool to view TPMS live data. Look for tire ID status, reception count, and any “ID not received” or “no signal” indicators that correspond to tire 1. If the scan tool labels “tire 1” by learned ID order, do not assume a physical corner yet. Confirm how the scan tool maps tire numbering on this Outlander.
6. Perform a controlled relearn or ID registration procedure per Mitsubishi service information. If the procedure requires a trigger tool, activate each sensor in the prompted order. If the tool supports it, measure signal strength and frequency. A sensor that will not trigger or shows weak output becomes a prime suspect, but keep verifying the receiver side first.
7. Inspect the TPMS ECU connectors and any receiver/antenna connectors used on this platform. Look for bent pins, spread terminals, corrosion, and water tracks. Tug-test the harness near strain points and body pass-throughs. Repair any damaged terminal tension before replacing parts.
8. Do circuit integrity checks on the receiver/antenna wiring if equipped. Use the wiring diagram to identify each circuit. Check for shorts to ground, shorts to power, and high resistance. When you find high resistance, isolate sections and load-test the circuit. A static ohms test can miss a broken strand fault.
9. If C1911 sets intermittently, road test with a scan tool snapshot running. Capture TPMS data changes, battery voltage, and any module reset indicators. Snapshot differs from freeze frame because you trigger it manually. Use it to catch the moment reception drops out.
10. Swap diagnostic inputs only after verification. If you can safely rotate wheels and the scan tool can re-identify sensors, see whether the “tire 1” failure follows a specific wheel/sensor ID or stays tied to the same channel. This step helps separate a sensor problem from a receiver/channel problem. Re-register IDs afterward if the system requires it.
11. Clear codes and run a complete verification. Confirm the TPMS system learns or retains IDs and shows stable reception for the previously failing tire 1 channel. Recheck for pending versus confirmed status after an appropriate drive cycle. A hard fault often returns immediately at key-on, while an intermittent fault may need two trips to confirm.

Professional tip: When C1911 appears after tire service, treat it as an ID management problem first. Confirm the shop did not install a non-compatible sensor or clone the wrong ID. Do not replace the TPMS ECU until you prove clean power and ground with voltage-drop testing and confirm the receiver path passes circuit checks.

Possible Fixes

• Register or relearn the TPMS sensor IDs correctly: Perform the Mitsubishi-specific ID registration procedure and confirm tire 1 reception returns in live data.
• Repair power or ground voltage drop to the TPMS ECU: Clean and tighten grounds, repair damaged power feeds, and correct poor junction block connections verified by load testing.
• Repair antenna/receiver circuit wiring or terminals: Fix opens, shorts, corrosion, or poor pin fit found during connector and harness inspection.
• Replace the TPMS sensor that fails to trigger or transmits weakly: Replace only after confirming the receiver circuits and module power/ground test good.
• Remove or relocate interference sources: Address aftermarket devices or shielding conditions that correlate with the reception drop during snapshot testing.
• Replace the TPMS ECU only after proving inputs and wiring: Consider the module last, and only after network presence, power/ground, and receiver circuit integrity checks pass.

Can I Still Drive With C1911?

You can usually drive a 2016 Mitsubishi Outlander with DTC C1911, because it reports a TPMS tire ID reception failure for tire 1, not a brake or steering fault. Treat it as a safety warning, not a drivability failure. The risk comes from losing accurate tire pressure warnings for that wheel position that the module labels as “tire 1.” If a tire loses air, the system may not alert you. Before driving at highway speeds, manually check and set cold tire pressures, then inspect the suspect wheel for obvious damage. If the TPMS warning stays on and you cannot confirm pressures, limit speed and distance until you correct the cause.

How Serious Is This Code?

C1911 ranges from an inconvenience to a real safety concern. It feels minor when all tires hold pressure and you verify pressure with a gauge. It becomes serious when you rely on TPMS to catch a slow leak, puncture, or bead leak. On Mitsubishi systems, the TPMS receiver or ECU expects to hear a specific sensor ID at each learned position. When it cannot receive the “tire 1” ID, the module sets a manufacturer-specific chassis DTC and may disable that wheel’s pressure display or warning logic. The vehicle will still accelerate, shift, and brake normally, but you lose a layer of protection against underinflation, heat buildup, and tire damage.

Common Misdiagnoses

Technicians often replace the tire pressure sensor first, because “ID reception failed” sounds like a dead sensor. That assumption wastes time when the real issue sits in the learn procedure, wrong sensor ID stored in memory, or RF interference. Another common miss involves wheel swaps. The Outlander may treat “tire 1” as a learned position, not a physical corner you can guess. Shops also overlook low sensor wake-up from a stationary vehicle. Many TPMS sensors transmit more often when rolling. Finally, people ignore power and ground integrity at the TPMS receiver or ECU. A marginal supply can block reception long before it sets a hard power fault.

Most Likely Fix

The most frequently confirmed repair directions for C1911 involve restoring correct ID recognition, not immediately replacing parts. First, verify the TPMS IDs match the sensors installed and that the Mitsubishi relearn procedure completed. Correct any ID-to-position mismatch created by tire rotation or sensor replacement. Second, inspect the receiver/ECU connectors and harness routing, then confirm clean power and ground under load. If those checks pass and live data still shows no reception from “tire 1” while the vehicle moves, then a failed sensor battery or damaged sensor becomes a justified next step.

Repair Costs

Repair cost depends on whether the confirmed root cause is wiring, connector condition, a sensor, a module, or the labor needed to diagnose the fault correctly.
