Tire Pressure Monitoring System (TPMS) Sensor Fault
The TPMS sensor is signaling a fault condition.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The tire pressure monitoring system is not working properly, possibly due to a faulty sensor or a communication issue with the vehicle's computer.
What the computer is actually seeing
The computer detects that one or more TPMS sensors are reporting a fault or not communicating.
What a healthy reading looks like
TPMS sensors should read pressures between 30-35 PSI when tires are properly inflated and communicate at a voltage of around 2.5V when active.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the tire pressures on all four tires; they should be within 30-35 PSI. If any tire is outside this range, inflate to the correct pressure.
- 22. Inspect the TPMS sensors for visible damage or corrosion at the connection points. Ensure that the wiring harness is intact and securely connected.
- 33. Use a TPMS scan tool to check if the sensors are communicating properly. Activate each sensor individually to confirm functionality.
- 44. If a sensor is unresponsive, replace that specific sensor and reprogram the TPMS system to recognize it.
- 55. If all sensors are functioning and pressures are correct, check for any grounding issues with the TPMS control module.
Common causes
- Faulty TPMS sensor
- Wiring issues between the sensor and the control module
- Battery failure in the TPMS sensor
- Improperly inflated tires
- Interference from aftermarket electronics

Frequently asked questions
Is it safe to drive with this code?
Yes, you can drive the vehicle, but it's advised to fix the issue soon as it affects tire safety and emissions compliance.
Will this code clear on its own?
If the underlying issue is not fixed, the code is unlikely to clear on its own and may reoccur.
Why does this code come with other codes?
This code may pair with other TPMS codes when multiple sensors are involved in the fault or if there are systemic issues with the TPMS system.
