C0555Left Front Wheel Speed Sensor A Incorrect Component Installed
- Generic OBD-II code · Chassis
- Turns on the check-engine light
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The left front wheel speed signal is present, but the ABS module concludes that the part behind it is not the one it expects. Mitsubishi maps its code C1061-4A on the 2023 Outlander PHEV to C0555 and defines it as the front left sensor fitted in the wrong position; the module needs no more than 3 s to flag it, provided the sensor supply is intact, and the second affected drive brings on the MIL together with the ASC and ABS warnings. ABS, EBD, ASC, traction control, hill descent control and the electric parking brake function are suspended. One way a module can spot this: sensor ICs such as Allegro's A19302 report rotation direction, with forward defined by mounting orientation, so a sensor of the wrong variant or side reads the wheel as turning backwards. After replacing a sensor, check the part number before anything else.

- Likely causes
- LikelyWrong sensor variant fitted (other side, other axle or passive instead of active)
- PossibleSensors or their connectors swapped between wheel positions
- RareABS control unit misjudges a correct sensor
- Repair
- Easy · Often possible to do yourself.Typical cost: €30 – €250
