TPMS Module Communication Fault
What does C0192 mean?
The C0192 code means the vehicle's onboard diagnostic system has detected: TPMS Module Communication Fault. This is a low severity code.
Common Symptoms
- All tire pressure readings missing
- TPMS warning light flashing
- TPMS system completely inoperative
- Scan tool cannot communicate with TPMS module
- No response from any TPMS sensor
Probable Causes (Ranked by Likelihood)
- TPMS receiver module failure Very High
- TPMS module power supply fault High
- CAN bus communication issue to TPMS module Moderate
- Corroded TPMS module connector Low
Step-by-Step Diagnostic Procedure
-
Check TPMS module power and ground
-
Attempt scan tool communication with TPMS module
-
Inspect TPMS module connector for corrosion
-
Check CAN bus wiring to TPMS module
-
Test TPMS module with known good unit if available
Frequently Asked Questions
Where is the TPMS receiver module?
The TPMS receiver is typically located inside the vehicle, often behind a trim panel in the wheel well area, under the dash, or in the trunk. Some vehicles integrate it into the BCM.
Can all four sensor failures mean a module problem?
Yes. If all four sensors stop communicating simultaneously, the TPMS receiver module is the most likely cause rather than all four sensors failing at the same time.
Does the TPMS module need programming?
Yes. A replacement TPMS module must be programmed with the sensor IDs and vehicle-specific parameters. This typically requires a dealer-level scan tool.
