What C0515 means
C0515 says the right rear sensor circuit draws or sees too much. GM's 2025 tables bundle four ASIC flags under this code: high-side current above 40 mA, high side shorted to battery, low-side overcurrent and, perhaps unexpectedly, a low side shorted to ground; each sets it after 100 ms as Type A. The 2023 tables keep it simpler: 50 mA exceeded for 0.12 s in the signal wire. Mitsubishi's C1067-12 equals C0515 and is described as a short circuit found within one second. GM's Silverado EV bulletin 24-NA-125 lists C0515 among the codes caused by the ABS harness touching the rear drive unit. A sensor shorted inside its housing is the other common source of overcurrent.
C0515 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0515
- ABS and stability lamps on as soon as the self-test ends
- Stability and traction control unavailable
Common causes of C0515
- Most likelyInsulation damage in the right rear harness causing a short
- PossibleRight rear sensor shorted internally
- Less likelySensor supply stage in the brake module defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0515 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 C0515
What does C0515 mean?
C0515 means "Right Rear Wheel Speed Sensor A Circuit High". C0515 says the right rear sensor circuit draws or sees too much. It is a generic code, so it means the same on every make.
Is it safe to drive with C0515?
Drive gently and only to a workshop. With C0515 the car can go into limp mode (reduced power) to protect itself.
Will C0515 fail an emissions test?
C0515 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 C0515 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C0515 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
