C0062Longitudinal Acceleration Sensor
- Generic OBD-II code · Chassis
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- C0062 flags the longitudinal acceleration signal, the fore-aft reading used for hill hold, grade detection, all-wheel-drive torque split and brake distribution. The module checks it against the change in wheel speed, braking and throttle and against the other inertial channels, and stores the code for a value out of range, frozen, noisy or implausible. FCA documents C0062-29, invalid signal, on the 2022 Jeep Compass with C0061-29 and C0063-29, lighting the MIL and the ESC and parking brake warnings until the ABS module receives new software (08-007-23). On the 2019 RAM 1500, FCA lists C0062 among the codes a PCM software update addresses (18-058-20). Stability and hill hold are switched off while the fault is present; normal braking remains.
