The C0062 code indicates a fault in the longitudinal acceleration sensor circuit. This sensor measures forward/backward acceleration and helps the vehicle's control modules manage engine and transmission behavior.
The sensor itself can fail internally, giving incorrect or no readings that trigger the code.
Corroded, broken, or loose connections to the sensor can interrupt the signal.
Internal breaks or poor contacts in the harness can cause intermittent or constant signal loss.
A fault in the transmission or drivetrain control module that processes the sensor input may mimic a sensor failure.
A rare PCM issue can misinterpret sensor data, but this is usually considered only after sensor and wiring checks.
No. The PCM is rarely the cause; most often the sensor or its wiring must be repaired first.
The vehicle may still run, but performance can be reduced and the engine could stall, so the issue should be addressed promptly.
A qualified technician typically completes the replacement in under an hour.
It can affect emissions control indirectly, but the primary concern is drivability and vehicle performance.
