Throttle Position Sensor
NOTE:
Throttle Position (TP) sensor is non-adjustable. Use following procedure to check TP sensor calibration. For complete testing of TP sensor and wiring circuit, refer to the appropriate TESTS W/CODES
article.
- Remove components for access to electrical connector at TP sensor, mounted on throttle body. With electrical connector installed on TP sensor, turn ignition on with engine off. DO NOT start engine.
- Using Digital Volt-Ohmmeter (DVOM), measure voltage at center terminal on electrical connector for TP sensor with throttle valve closed (idle position). Voltage should be greater than .6 volt.
- Slowly open throttle to full throttle and note voltage reading. Voltage should smoothly increase to less than 4.5 volts. Replace TP sensor if voltage is not within specification.
