Accelerator Pedal Position Sensor (Diamante W/Traction Control)

  1. Sensor is connected to throttle valve. Disconnect sensor connector. Measure resistance between terminals No. 1 and No. 4. Resistance should be 3500-6500 ohms.
  2. Using analog ohmmeter, measure resistance between terminals No. 1 and 3. Monitor ohmmeter while slowly opening throttle from idle position to WOT. Resistance should change smoothly in proportion with throttle opening. Replace sensor if ohmmeter displays erratic changes in resistance when opening throttle.
  3. Check for open or short in circuit between accelerator pedal position sensor and PCM. Disconnect sensor and PCM connectors. Connect ohmmeter between sensor connector terminal No. 4 and vehicle ground. Ground PCM connector terminal No. 81. Repair circuit as needed if continuity does not exist.
  4. Check for continuity between sensor connector terminal No. 1 and vehicle ground. Repair circuit between sensor connector terminal No. 1 and PCM terminal No. 92 as needed if continuity does not exist. Connect PCM connector. Turn ignition on. Using DVOM, measure voltage between sensor connector terminal No. 4 and ground. Voltage should be 4.8-5.2 volts. Replace PCM is voltage is not within specification.
