C0952 code meaning
Tire Pressure Monitoring Sensor Rear Left
What C0952 means
A manufacturer using C0952 is not on record; the number is absent from all lists and bulletins searched. What it names, the left rear tire sensor, carries other codes elsewhere: C0760 at GM and Saab, C1734 and C1744 in Mitsubishi's 2022 index, and on a 2008 Honda Accord the codes 37 for a low sensor battery and 38 for a sensor that stopped transmitting at the left rear. Relearning follows a fixed sequence of corners; Honda starts with the front left wheel, moves on to the rear left one, then the rear right, and finishes at the front right, and Saab's autolearn tells the axles apart by signal strength. A left rear fault therefore often follows a wheel rotation or a missed relearn step. The left rear pressure is no longer monitored.

Symptoms of C0952
- No reading for the left rear tire
- TPMS warning after a tire rotation
Common causes of C0952
- Most likelyWheels rotated without relearning sensor positions
- PossibleCell of the left rear sensor exhausted
- PossibleSensor damaged or missing after tire work
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0952 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 C0952
What does C0952 mean?
C0952 means "Tire Pressure Monitoring Sensor Rear Left". A manufacturer using C0952 is not on record; the number is absent from all lists and bulletins searched. It is a generic code, so it means the same on every make.
Is it safe to drive with C0952?
C0952 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will C0952 fail an emissions test?
C0952 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 C0952 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will C0952 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.
