C0556Right 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
- Mirror of C0555 for the right front wheel: the sensor delivers pulses, yet the ABS module rejects it as the wrong component. Mitsubishi lists its code C1063-4A on the 2023 Outlander PHEV as C0556, with the same rule (fitted at the wrong position, at most 3 s, two trips to MIL plus ASC and ABS lamps). Worth noting from that procedure: a code that is only stored, not active, may simply mean the car was not driven after the last repair, and the ABS unit should not be replaced for it; the check needs about 2 minutes at 50 km/h or more. HELLA notes that powered (active) and self-generating (passive) sensors are often hard to tell apart by eye and that carmakers have mostly fitted active ones since 1998, which makes a mixed-up spare part a realistic cause. Circuit faults on this wheel show up as C0506 or C0034 instead.
