Decreased engine power and acceleration
Illuminated check engine light
Hesitation or stuttering during acceleration
Fault Throttle/Pedal Position Sensor/Switch C or the associated circuit
Loose coupler/connector associated with the sensor
Internal ECM fault (less likely)
Throttle Position Sensor: Throttle position sensor generally denotes the position of the accelerator pedal. Problems lead to poor acceleration
Replace the Throttle/Pedal Position Sensor/Switch C
If no faults found in the sensor or associated circuit, the ECM may need to be repaired/replaced
