Tire Pressure Monitoring System Sensor Malfunction
What does C0175 mean?
The C0175 code means the vehicle's onboard diagnostic system has detected: Tire Pressure Monitoring System Sensor Malfunction. This is a low severity code.
Common Symptoms
- TPMS warning light on
- Tire pressure not displayed for one or more tires
- TPMS warning light flashing then staying solid
- Incorrect tire pressure readings on dash
- TPMS system fault message
Probable Causes (Ranked by Likelihood)
- Failed TPMS sensor battery Very High
- Damaged TPMS sensor during tire service High
- TPMS sensor not relearned after tire rotation Moderate
- TPMS receiver module fault Low
Step-by-Step Diagnostic Procedure
-
Scan TPMS module for sensor IDs and status
-
Check which sensor is not reporting
-
Use TPMS activation tool to trigger each sensor
-
Verify sensors were relearned after recent tire service
-
Inspect sensor for physical damage
Frequently Asked Questions
How long do TPMS sensor batteries last?
TPMS sensor batteries typically last 5-10 years or 50,000-100,000 miles. Once the battery dies, the entire sensor must be replaced as the battery is sealed inside.
Why does my TPMS light flash then stay on?
A flashing TPMS light that then stays solid indicates a system fault, usually a failed or unresponsive sensor. A steady TPMS light without flashing typically means low tire pressure.
Can I replace a TPMS sensor myself?
The sensor itself requires removing the tire from the wheel. However, some vehicles allow DIY sensor relearn procedures using a TPMS tool or specific button sequences on the vehicle.
