Diagnosis & Repair Procedure

  1. If engine system check has been performed, go to next step. If engine system check has not been performed, go to A4: ENGINE SYSTEM CHECK  under SYSTEM TESTS.
  2. Turn ignition on. Using scan tool, observe MAP sensor parameter. If parameter reads 5 kPa or less, go to next step. If parameter reading is more than 5 kPa, problem is probably intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
  3. Turn ignition off. Disconnect MAP sensor 3-pin harness connector. Check MAP sensor harness connector for poor connection. See WIRING DIAGRAMS article. If problem is found, repair as necessary. After repair, repeat DTC CONFIRMATION TEST  . If no problem is found, go to next step.
  4. Measure voltage between ground and MAP sensor harness connector terminal No. 3 (Pink wire) and No. 2 (Green wire), individually. If voltage reading is 4-6 volts on both wires, go to next step. If voltage 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 .
  5. Substitute a known good ECM, and repeat DTC CONFIRMATION TEST  . If DTC resets, go to next step. If DTC does not reset, testing is complete.
  6. Test MAP sensor. Turn ignition off. Remove MAP sensor. Connect three 1.5 volt batteries in series. Connect positive terminal of batteries to MAP sensor terminal No. 3 (V in). Connect negative terminal of batteries to MAP sensor terminal No. 1 (GROUND). See Fig 1 . Using DVOM, measure voltage between MAP sensor terminal No. 2 (V out) and ground side of batteries. Voltage reading should be 4.5-5 volts. If voltage is as specified, leave battery pack and DVOM connected, and go to next step. If voltage is not as specified, replace MAP sensor. After repair, repeat DTC CONFIRMATION TEST  .
  7. Using hand-held vacuum pump apply specified vacuum to MAP sensor, and check MAP sensor output voltage at specified pressure. See Fig 2 . If output voltage is as specified, substitute a known good ECM, and repeat DTC CONFIRMATION TEST  . If voltage output is not as specified, replace MAP sensor.
