THROTTLE POSITION SENSOR
The TP sensor monitors throttle position and provides an electrical signal to the PCM. It is monitored by the On-Board Diagnostic (OBD) II system for component integrity, system functionality, and faults that can cause emissions levels to exceed standards set in government regulations. For additional information on the TP sensor, refer to Electronic EC System Hardware-PCM Inputs.
