Diagnosis & Repair Procedure

  1. Perform DTC CONFIRMATION TEST  . If DTC P0107 is set, go to next step. If DTC P0107 is not set, problem is intermittent. System is okay at this time. See TROUBLE SHOOTING - NO CODES article.
  2. Check for DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. If DTC P0107, P0122 and P0450 are set, check for an open in Pink wire between ECM 16-pin connector C20 terminal No. 1 and MAP sensor connector terminal No. 3. See Figure . See WIRING DIAGRAMS article. Repair as necessary and go to DTC CONFIRMATION TEST  . If DTC P0107, P0122 and P0450 are not set and/or Pink wire is okay, go to next step.
  3. Turn ignition on. Using scan tool, select MAP sensor parameter. If parameter reads 5 kPa or less, go to next step. If parameter reading is more than 5 kPa, problem is intermittent. System is okay at this time. See TROUBLE SHOOTING - NO CODES article.
  4. Turn ignition off. Disconnect MAP sensor connector. Check MAP sensor connector for poor connection. See WIRING DIAGRAMS article. Repair as necessary and go to DTC CONFIRMATION TEST  . If connection is okay, turn ignition on. Measure voltage between ground and MAP sensor harness connector terminal No. 3 (Pink wire) and No. 2 (Green wire), individually. Go to next step.
  5. If reading are 4-6 volts on both wires, go to next step. If readings are not 4-6 volts on either wire, check for open or short to ground in Pink wire between MAP sensor and ECM 16-pin connector C20 terminal No. 1, or Green wire between MAP sensor and ECM 16-pin connector C20 terminal No. 5. See Figure . If wires are okay, check for poor connection at ECM 16-pin harness connector C20. Repair as necessary and go to DTC CONFIRMATION TEST  . If connection is okay, replace ECM and go to DTC CONFIRMATION TEST  .
  6. Turn ignition off. Remove MAP sensor. Connect three 1.5 volt batteries in series. Ensure total battery output is 4.5-5 volts. Connect positive terminal of batteries to VOLTAGE IN terminal at MAP sensor. Connect negative terminal of batteries to GROUND terminal at MAP sensor. See Fig 1 . Go to next step.
  7. Test MAP sensor operation. See SYSTEM & COMPONENT TESTING article. Replace MAP sensor as necessary and go to DTC CONFIRMATION TEST  . If MAP sensor is okay, replace ECM and go to DTC CONFIRMATION TEST  .
