Accelerator Pedal Position Sensor (Diamante With Traction Control)

WARNING: This page is about a different car, the 1994 Mitsubishi Diamante. However, it is still accessible from the selected car via links, so may be relevant.
  1. Sensor is connected to throttle valve. Disconnect sensor connector. Measure resistance between terminals No. 1 and No. 4. Resistance should be 3.5-6.5 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 ECM. Disconnect sensor and ECM connectors. Connect ohmmeter between sensor connector terminal No. 4 and vehicle ground. Ground ECM connector terminal No. 61 (Fed. models) or terminal No. 81 (Calif. models). 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 ECM terminal No. 72 (Fed. models) or terminal No. 92 (Calif. models) as needed if continuity does not exist. Connect ECM connector. Turn ignition on. Using DVOM, measure voltage between sensor connector terminal No. 4 and vehicle ground. Voltage should be 4.8-5.2 volts. Replace ECM is voltage is not within specification.
