C0500Left Front Wheel Speed Sensor A Circuit/Open
- Generic OBD-II code · Chassis
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- C0500 flags lost continuity in the left front wheel speed sensor circuit. An active sensor draws a steady current even with the car parked; Allegro gives 7 and 14 mA as the usual levels of a two-wire interface, so a reading near zero means a broken path. GM's 2016 hybrid OBD tables set C0500 once the signal-line current stays under 3.8 mA for 0.12 s, rated Type A (MIL on the first trip), and suppress it while C05A4 reports a low sensor supply. Mitsubishi maps C1061-13 to C0500 with a delay of at most 1 s and the check-engine lamp after one trip. Unrelated: a Stellantis brake bulletin for the 2022–2023 Wagoneer uses C0500-00 for a hydraulic leak. With this code ABS, stability and traction control shut down.
