C0035 code meaning
Right Front Wheel Speed Sensor Supply
What C0035 means
C0035 reports a fault in the feed that powers the right front active wheel speed sensor, the right-hand partner of C0032. The ABS/ESC module supplies the sensor with a regulated voltage; an open feed, a short to ground or to another voltage, or a supply outside its window leaves the sensor unable to send a speed signal. NHTSA's EPS safety report lists C0035 with this meaning in its table of J2012 wheel speed codes. Caution with older GM vehicles: GM numbers its four wheel speed sensor circuits C0035 to C0050 in its own scheme (bulletin 16-NA-248, PIE0456), so a GM C0035 is a sensor circuit fault rather than a supply fault. ABS, traction and stability control switch off and the ABS lamp lights; normal braking remains.
C0035 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0035
- ABS warning lamp on
- ABS, traction and stability control disabled
- No speed signal from the right front wheel
Common causes of C0035
- Most likelyOpen or shorted supply wire to the right front sensor
- PossibleCorroded or loose sensor connector
- PossibleSensor shorted internally and pulling the supply down
- Less likelySensor supply output of the ABS module faulty
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). |
| 35 | The exact fault in that area. |
What to do next
- Note C0035 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 C0035
What does C0035 mean?
C0035 means "Right Front Wheel Speed Sensor Supply". C0035 reports a fault in the feed that powers the right front active wheel speed sensor, the right-hand partner of C0032. It is a generic code, so it means the same on every make.
Is it safe to drive with C0035?
Drive gently and only to a workshop. With C0035 the car can go into limp mode (reduced power) to protect itself.
Will C0035 fail an emissions test?
C0035 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 C0035 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C0035 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
