C1506 Quick Answer
C1506 indicates: Left Front Tire Pressure Trigger Module Performance. Confirm all four sensors are reporting; a missing sensor often resolves to a flat battery in the sensor (typical 5-7 year life) rather than a wiring fault.
What Does C1506 Mean on a Chrysler 300C?
The Chrysler 300C LX platform stores C1506 when the affected module detects left front tire pressure trigger module performance. This code is logged by the controller responsible for the tires/wheels system on this vehicle. The applicable model years cover the LX platform production run (2005-2010 for the 300C; the same code definitions apply to the related Charger, Magnum, and Challenger LX-platform vehicles when fitted with the same module).
Symptoms
Symptoms vary with the specific subsystem affected, but commonly include one or more of:
- Warning light or indicator on the instrument cluster
- Reduced functionality of the affected system (tires/wheels)
- Loss of related convenience or safety features
- Possible co-codes from connected modules on the CAN bus
Common Causes
- Fault in the named component, sensor, or actuator circuit
- Open or shorted wiring in the affected circuit
- Connector corrosion, water ingress, or backed-out terminal
- Loss of supply voltage or ground at the affected device
- Module internal fault (rare — verify wiring and supplies first)
Diagnostic Approach
For C1506 on the Chrysler 300C LX you’ll need a TPMS-aware scan tool that can re-learn sensor IDs, plus a TPMS sensor activator if the car uses single-zone learn.
- Confirm all four sensors are reporting; a missing sensor often resolves to a flat battery in the sensor (typical 5-7 year life) rather than a wiring fault.
- Verify the fault is current (active) and not just stored history. Some 300C LX modules retain history codes for many cycles after the underlying issue is resolved.
- Inspect the connector at the device named in the code description. The LX-platform harnesses suffer from terminal-tension loss in flex zones — wiggle-test the connector while monitoring live data.
- Measure supply voltage and ground integrity at the affected device with the engine running.
- If supplies are good and the connector is sound, isolate the device with a known-good substitute or a load resistor matching the expected impedance.
- Clear the code, drive the vehicle through one or two cycles to confirm the fault does not return.
Possible Fixes
- Replace the failed device named in the code description
- Repair open or shorted wiring
- Connector pin-tension or pigtail repair
- Module replacement and programming if the module itself is faulty
Can I Still Drive With C1506?
Drivability impact depends on the affected subsystem. TIRES/WHEELS faults that affect a primary safety system (brakes, restraints, steering) should be repaired before further driving. Comfort or convenience-system faults can usually be deferred briefly without immediate safety risk, but should still be addressed to prevent the fault from cascading into related codes.
How Serious Is This Code?
C1506 is a TIRES/WHEELS code on the Chrysler 300C LX. Address based on subsystem priority: brake, airbag, and steering codes are urgent; comfort, lighting, and audio codes are moderate priority. Network-communication codes can hide other faults and should be diagnosed early in the troubleshooting flow.
FAQ
Will C1506 clear itself on a Chrysler 300C?
If the underlying fault was a momentary glitch — for example a brief connector dropout or a one-time low-voltage event — the C1506 may clear after a few drive cycles. Persistent root causes (failed device, broken wire, corroded terminal) will keep the fault active until the affected component is repaired on the Chrysler 300C.
Can I drive my Chrysler 300C with C1506 active?
It depends which subsystem is affected. If the C1506 is in a primary safety system (brakes, restraints, steering, air suspension), the Chrysler 300C should be driven only to a workshop. Comfort, lighting, and audio faults are lower priority but still worth addressing — the Chrysler 300C’s CAN architecture means a single unresolved code can mask others.
How much does it cost to fix C1506 on a Chrysler 300C?
Repair cost depends on the named device. On the Chrysler 300C, simple connector or wiring repairs typically run $80-200 in shop labour. Sensor replacements run $120-450 including parts and diagnostic time. Module replacement (when the affected control module itself has failed) is the most expensive path at $400-1,200 depending on whether the new module needs programming.

What does the official Chrysler 300C service definition say about C1506?
Per the factory service information, C1506 is defined as: Left Front Tire Pressure Trigger Module Performance. The diagnostic procedure is in the Chrysler 300C service-manual chapter for the affected module.
