What C0507 means
C0507 flags an implausible right front speed signal. In GM's 2019 tables the brake module's ASIC watches the sensor current itself: a level hanging in the grey zones between 7 and 14 mA or 14 and 28 mA for 750 ms points to a high-resistance harness or leakage to battery voltage. Those bands sit between the base, data and speed-pulse levels Allegro lists for AK-protocol sensors. Further C0507 checks there look at standstill pulse width and timing. Mitsubishi assigns C1063-92, evaluated from 10 to 60 km/h. Stellantis bulletins show engine controllers storing the code too, for example on the 2016 Jeep Renegade 2.4 (18-061-16) and the 2026 Dodge Charger Sixpack (18-022-26); for the Charger, the bulletin blames a monitor lacking robustness and prescribes reprogramming.
C0507 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of C0507
- ABS/ESC lamps after driving off
- Code present only in the engine controller during a full vehicle scan
Common causes of C0507
- Most likelyCorroded contacts or damaged insulation causing resistance or leakage current
- PossibleDamaged tone ring or wrong tire size on the right front
- Less likelyEngine controller software storing the code falsely (Stellantis)
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). |
| 07 | The exact fault in that area. |
What to do next
- Note C0507 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 C0507
What does C0507 mean?
C0507 means "Right Front Wheel Speed Sensor A Range/Performance". C0507 flags an implausible right front speed signal. It is a generic code, so it means the same on every make.
Is it safe to drive with C0507?
Drive gently and only to a workshop. With C0507 the car can go into limp mode (reduced power) to protect itself.
Will C0507 fail an emissions test?
C0507 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 C0507 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C0507 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.
