Tire Pressure Monitoring System (TPMS) Sensor Fault
TPMS sensor is malfunctioning or not communicating.
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 sensor in one of your tires isn't working correctly, so the computer can't tell if your tires are properly inflated.
What the computer is actually seeing
The TPMS control unit detects a fault signal from one of the tire pressure sensors, usually due to a communication error, low battery in the sensor, or sensor replacement issues.
What a healthy reading looks like
Each TPMS sensor should transmit a signal that indicates the tire pressure is within 28-35 PSI range while the vehicle is in motion.
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.
- 1Check the tire pressures manually to verify that they are within the expected range (28-35 PSI).
- 2Inspect the TPMS sensors' wiring and connectors for damages or corrosion.
- 3Scan the system with a TPMS diagnostic tool to check for additional codes related to specific sensors or modules.
- 4If a specific sensor is highlighted in the diagnostic tool, swap it with another known good sensor and see if the fault code changes accordingly.
- 5If the code persists after checking wiring and swapping sensors, consider replacing the TPMS control module.
Common causes
- Defective TPMS sensor
- Weak sensor battery
- Improperly installed sensor
- Faulty wiring or connector
- Bad TPMS control module

Will this code come back after repairs?
If the issue is fixed correctly, it should not return.
Why does this code show up with other tire-related codes?
Common wiring issues or sensor faults can trigger multiple error codes.
