Test Procedures

  1. Turn ignition off. Disconnect acceleration sensor 3-pin connector. Turn ignition on. Measure voltage between ground and acceleration sensor connector terminal No. 1 (Green/Black wire). Voltage should be about 5 volts. If voltage is as specified, go to next step. If voltage is not as specified, repair open in Green/Black wire between acceleration sensor and ECM connector terminal No. 32. When repairs are completed, clear DTC and verify system operation.
  2. Measure resistance between ground and acceleration sensor connector terminal No. 2 (Green wire). If resistance is one ohm or less, go to next step. If resistance is more than one ohm, repair open in Green wire between acceleration sensor and ECM connector terminal No. 17. When repairs are completed, clear DTC and verify system operation.
  3. Disconnect ECM 63-pin connector. Connect a jumper wire between ground and acceleration sensor connector terminal No. 3 (Green/Orange wire). Measure resistance between ground and ECM connector terminal No. 60 (Green/Orange wire). If resistance is one ohm or less, remove jumper wire and go to next step. If resistance is more than one ohm, repair open in Green/Orange wire between acceleration sensor and ECM. When repairs are completed, clear DTC and verify system operation.
  4. Remove jumper wire. Check for continuity between ground and acceleration sensor connector terminal No. 3 (Green/Orange wire). If continuity does not exist, go to next step. If continuity exists, repair short to ground in Green/Orange wire between acceleration sensor and ECM. When repairs are completed, clear DTC and verify system operation.
  5. Measure resistance between acceleration sensor connector terminals No. 1 and 2 (component side). Resistance should be about 21,000 ohms. If resistance is as specified, go to next step. If resistance is not as specified, replace acceleration sensor. When repairs are completed, clear DTC and verify system operation.
  6. Reconnect acceleration sensor connector and ECM connector. Start engine and allow to idle. Backprobe and measure voltage between acceleration sensor connector terminal No. 3 (Green/White wire) and ground. Voltage should be 2.3-2.7 volts. If voltage is as specified, ensure ECM connector terminals are clean and tight. If ECM connector is okay, replace acceleration sensor. If problem persists, replace ECM. If voltage is not as specified, replace acceleration sensor. When repairs are completed, clear DTC and verify system operation.
