Throttle Position Sensor (TP Or TPS)

Faults in TP sensor or circuit should set a service code. See Quick Test procedure in TESTS W/CODES EEC-IV article in the ENGINE PERFORMANCE Section. If no service code has been set, see CIRCUIT TEST DH in TESTS W/CODES EEC-IV article for additional sensor testing and specifications. Ensure none of the following conditions exist:

• Binding Throttle Linkage
• TP Sensor Loose Or Not Seated Properly
• Throttle Plate Not Fully Closed
