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.

Likely causes

Corroded contacts or damaged insulation causing resistance or leakage current

Damaged tone ring or wrong tire size on the right front

Engine controller software storing the code falsely (Stellantis)

Symptoms

ABS/ESC lamps after driving off
Code present only in the engine controller during a full vehicle scan
