When the sensor fails to send a signal to the engine control module (ECM), it triggers the P2751 code, indicating a lack of communication between the sensor and the ECM.
Common Causes of P2751
- Faulty Intermediate Shaft Speed Sensor 'C'
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Transmission fluid contamination
- Mechanical issues in the transmission
Symptoms of P2751
- Rough or erratic shifting
- Transmission slipping out of gear
- Delayed engagement when shifting
