C0508Right Front Wheel Speed Sensor A Circuit Low
- Generic OBD-II code · Chassis
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- C0508 reports the right front sensor circuit below range. A 2024 Jeep Wrangler case from the Stellantis STAR center shows a typical picture: after an earlier repair the ABS lamp came on with C0508-00, ABS disabled and implausible-speed network codes; the sensor harness had been pinched and only needed rerouting. Audi's bulletin 2061331/1 for 2017–2021 A4 and A5 family cars stores C050800 as short to ground when a wire is poorly crimped in the front sensor connector. GM's 2023 tables use C0508 for signal patterns that the current, supply and voltage monitors cannot classify as either a fault or a valid signal (0.12 s, Type A). Mitsubishi's C1063-11 covers short and open circuits on the right front and also lights the parking brake warning.
