CAUTION:
If Engine Control Module (ECM) replacement is instructed in following test, always ensure ECM electrical connectors and ground circuits are okay. If either are defective, repair and repeat testing to confirm ECM malfunction.
NOTE:
If DTCs related to MAF meter, IAT sensor, TPS, ECT sensor, HO2S, VPS and/or A/C Lock sensor are output simultaneously, the E2 sensor ground circuit at ECM 34-pin connector E7 terminal No. 28 (Black/White wire) may be open. See ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in ELECTRICAL. For ECM connector terminal identification, see Figure. It may be necessary to check splice I3. Splice I3 is located behind passenger's side of instrument panel. See Figure.
