C251D Chrysler Atlantic OBD Code

OBD/2 C251D error code description and symptoms.

The Transmission Range Sensor (also referred to as the PRNDL input an/or neutral safety switch) tells the transmission control module (TCM) an the engine control module (PCM) that the transmission is in park, reverse, neutral, drive, low, 2nd, 3rd etc. It is attached directly to the manual valve of transmission, so when the shift lever is moved from park to drive, the Transmission Range Sensor communicates this critical information to the above mentioned vehicle control module systems.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C251D, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C251D on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

Likewise, overriding the OBD C251D error in system through the use of high-tech defeat devices or non-certified computer chips, for example, would also be considered tampering. The OBD system may, however, be repaired back to its original certified configuration with certified performance chips or appropriate aftermarket parts.
