1) Connect scan tool MB991502 to the data link connector.
2) Turn the ignition switch to the "ON" position.
3) Set scan tool MB991502 to the data reading mode for item 11: Throttle Position Sensor.
- With the throttle valve in the idle position, voltage should be between 535 and 735 mV.
- With the throttle valve in the full-open position, voltage should be between 4,500 and 5,500 mV.

4) Turn the ignition switch to the "LOCK"(OFF) position.
Q: Is the sensor operating properly?
YES: This malfunction is intermittent.
NO: Replace the PCM.








STEP 6. Check connectors B-07 at the throttle position sensor and C-117 <2.4L Engine> or C-119 <3.0L Engine> at the PCM for damage.
Q: Are the connectors in good condition?
YES: Repair it because of harness open circuit or damage between throttle position sensor connector B-07 terminal 3 and PCM connector C-117 <2.4L Engine> or C-119 <3.0L Engine> terminal 78.
NO: Repair or replace it.
