Throttle Position (TP) Sensor

DESCRIPTION
Is a potentiometer mounted on the throttle body. The throttle position sensor detects the position of the throttle plate and sends this information to the PCM as a varying voltage signal. If a malfunction occurs in the TP sensor circuit, the PCM will recognize that the TP sensor signal is out of specification. The PCM will then operate the AX4S transaxle in a high capacity mode to prevent transaxle damage. The PCM also uses this signal for shift scheduling, EPC pressure control, torque converter clutch control.

SYMPTOMS
Harsh engagements, firm shift feel, abnormal shift schedule, torque converter clutch does not engage, torque converter clutch cycling.
