TPMS System Not Calibrated
What does C0195 mean?
The C0195 code means the vehicle's onboard diagnostic system has detected: TPMS System Not Calibrated. This is a low severity code.
Common Symptoms
- TPMS warning light on
- Tire pressures displayed but seem incorrect
- TPMS light came on after tire change
- Indirect TPMS showing false low pressure warnings
- TPMS reset button procedure not completed
Probable Causes (Ranked by Likelihood)
- TPMS system not reset after tire service Very High
- Incorrect base tire pressure set during calibration High
- Tires changed to different size without recalibration Moderate
- TPMS calibration data corrupted Low
Step-by-Step Diagnostic Procedure
-
Verify all tire pressures are correct per door placard
-
Perform TPMS calibration or reset procedure
-
Check if tire sizes match vehicle specifications
-
Use TPMS reset button or menu in infotainment
-
Drive vehicle at specified speed for calibration learning
Frequently Asked Questions
What is an indirect TPMS system?
Indirect TPMS does not use pressure sensors in the tires. Instead, it monitors wheel speed differences via ABS sensors to detect an underinflated tire, which rolls at a slightly different speed.
How do I reset my TPMS?
For direct TPMS, inflate all tires to the correct pressure and use the TPMS reset button or infotainment menu. For indirect TPMS, follow the calibration procedure in your owner's manual.
Does changing tire size require TPMS recalibration?
Yes. If you change tire sizes, the TPMS system must be recalibrated to account for the different rolling diameter. Failing to do so will result in incorrect pressure readings or false warnings.
