C0951 code meaning
Tire Pressure Monitoring Sensor Front Right
What C0951 means
C0951 is not documented by any known maker. For the front right sensor GM and Saab rely on C0755 instead, on the 2011 9-4X with the subcodes 03, 29 and 39. Mitsubishi's 2022 data spell out the no-data case in detail as C1742-21: the BCM watches for the right front signal once the car has covered 10 minutes in total at 40 km/h or more, and it stores the code if nothing arrives. Its listed causes reach beyond the sensor: driving through radio interference, an incomplete ID registration, wiring or the BCM itself. A front right sensor code therefore calls for checking the learned ID and the surroundings before buying a sensor. The driver loses the front right reading and sees the TPMS warning.
C0951 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of C0951
- Dashes instead of a value for the right front tire
- TPMS lamp lit after about ten minutes of driving
Common causes of C0951
- Most likelyID registration of the front right sensor incomplete
- PossibleSensor cell exhausted
- PossibleRadio interference along the route or from devices in the car
- Less likelyReceiving control module defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 51 | The exact fault in that area. |
What to do next
- Note C0951 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0951
What does C0951 mean?
C0951 means "Tire Pressure Monitoring Sensor Front Right". C0951 is not documented by any known maker. It is a generic code, so it means the same on every make.
Is it safe to drive with C0951?
C0951 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will C0951 fail an emissions test?
C0951 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0951 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will C0951 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
