Safe to drive; check tire pressures by hand. C0760 is a chassis code that flags a problem with one tire pressure monitoring (TPM) sensor — on General Motors vehicles it identifies the left-rear wheel sensor, which stopped transmitting or reported a low internal battery. The car drives normally, but that corner's pressure is no longer being watched.
What C0760 means
C0760 belongs to the tire pressure monitoring system. Each wheel carries a battery-powered sensor that measures pressure and broadcasts a radio-frequency (RF) signal along with an 8-digit ID. A receiver module — on many GM platforms the remote control door lock receiver (RCDLR) — listens for these transmissions and knows which sensor sits at which corner. Above roughly 40 km/h (25 mph) a centrifugal roll switch inside each sensor closes, putting it into "rolling" mode so it reports more often. If the receiver hears nothing from one sensor for about 18 minutes, or the sensor reports a low internal battery, it stores the matching code. On GM applications C0760 is the left-rear position specifically (its siblings C0750, C0755, and C0765 cover the other three corners). Because C-codes are manufacturer-specific, the exact wheel and even the system a given control module blames can differ between brands, so always confirm the descriptor against the vehicle you are working on. The sensor battery is sealed and not serviceable, so a weak or dead battery means the whole sensor is replaced; a fresh sensor then has to be "learned" to the correct corner so the code points at the right wheel.
Symptoms
- Tire pressure warning icon flashes for about a minute at start-up, then stays lit
- Driver information center shows dashes or a "Service Tire Monitor" message for one tire
- One wheel position reports no pressure value on a scan tool or the dash display
- No genuine low-pressure alert appears even when that tire is actually soft
- Vehicle otherwise drives and handles completely normally — the fault is monitoring-only
Common causes
- Dead or weak sensor internal battery — the most common cause on vehicles more than 5–10 years old
- Damaged or failed TPM sensor, often from a previous tire-service or flat-tire event
- Sensor not transmitting because of a stuck roll switch or being parked (no signal for 18+ minutes)
- Sensor mislocated after a tire rotation performed without running the sensor relearn procedure
- RF interference or a blocked pressure port — aftermarket electronics, metallic window tint, or non-approved tire sealant
- Faulty receiver module (RCDLR) or an aftermarket valve stem that mispositions the sensor antenna
Severity & driving advice
Severity: Low — The car drives normally, but the flagged tire is no longer monitored, so check all four pressures manually until the sensor is repaired.

Diagnostic approach
- Confirm the code and the flagged corner — Scan for stored codes and read the descriptor — on GM vehicles C0760 is the left-rear sensor. Note whether it is current or history and check for the companion codes C0750/C0755/C0765. A single-corner code usually points at one sensor rather than the receiver or wiring.
- Read live sensor data — With a scan tool, open the receiver/RCDLR data list and check the suspect sensor's battery status, pressure, and ID. A low-battery flag confirms the sensor is at end of life and must be replaced, since the battery is sealed inside the sensor and cannot be serviced separately.
- Activate and verify the sensor — Use a TPM activation tool (GM special tool J-46079) held within 15 cm (6 in) of the sensor, aimed upward. A good sensor returns its 8-digit ID, a pressure within about ±27.6 kPa (4 psi), learn mode, and at least a quarter-scale signal. If it will not respond after up to three tries, the sensor is the likely fault.
- Rule out relearn and interference issues — If the sensor responds but the code persists, verify the sensor IDs and locations on the scan tool match the physical corners; a mismatch means the relearn was skipped. Also check for aftermarket valve stems, tire sealant blocking the port, or RF interference from add-on electronics before condemning parts.
- Replace, relearn, and road test — Replace a confirmed-bad sensor, then run the sensor learn procedure so the receiver assigns the new ID to the correct corner. Clear the code and drive above 40 km/h (25 mph) for a few minutes so the sensor enters rolling mode; a current code clears once the fault is gone and one ignition cycle completes.
Make & model notes
General Motors: On GM vehicles (Chevrolet, GMC, Buick, Cadillac) C0760 is the left-rear tire pressure sensor. The receiver sets it when that sensor is silent for about 18 minutes or reports a low battery, above 25 mph. The sensor battery is not serviceable — replace the sensor and run the learn procedure. Watch for mislocated sensors after a rotation done without a relearn.
Other manufacturers: C-codes are manufacturer-defined, so C0760 does not map to the same wheel — or even the same subsystem — on every brand. Some makes may assign it to a different chassis or TPM function entirely. Always confirm the exact descriptor from the vehicle's own service data before ordering a sensor or module.
FAQ
Is it safe to drive with a C0760 code?
Yes. C0760 only means one tire's pressure sensor has stopped reporting, so the vehicle drives and handles normally. The catch is that the affected tire — the left rear on GM vehicles — is no longer being watched, so check all four pressures by hand and top them up until the sensor is fixed.
Why does C0760 point to a specific wheel?
Each sensor broadcasts a unique 8-digit ID that the receiver has learned to a physical corner. On GM applications C0760 is tied to the left-rear position, while C0750, C0755, and C0765 cover the other three wheels. That is why the code can name one tire so precisely.
Can I just replace the sensor battery?
No. The battery is sealed inside the TPM sensor and cannot be changed on its own, so a weak or dead battery means the whole sensor is replaced. Sensor batteries typically last around 5 to 10 years, which is why this code is common on older vehicles.
Will C0760 come back after I replace the sensor?
It can if the new sensor is not learned to the correct corner. After fitting a sensor you must run the relearn procedure so the receiver assigns the new ID to that wheel, then drive above 25 mph for a few minutes. If you skip the relearn, the system can still flag the position as missing or mislocated.
