Throttle Position (TP) Sensor

  1. Turn ignition on. Measure voltage between ground and center terminal at TP sensor connector. At idle, voltage should be more than .2 volt.
  2. Gradually open throttle plate. Output voltage should gradually increase as throttle plate is opened. At wide open throttle, voltage should be less than 4.8 volts.
  3. If voltages are not as specified, make sure 5-volt input and ground circuits between TP sensor and PCM are okay. Repair circuits as necessary. If TP sensor output voltages are still not as specified, replace TP sensor.
