| CHECK HARNESS BETWEEN ECM AND REAR OXYGEN SENSOR CONNECTOR. |
|
1) Turn the ignition switch to ON. 2) Measure the voltage between rear oxygen sensor connector and chassis ground. Connector & terminal (T6) No. 3 (+) — Chassis ground (−): |
| QUESTION | |
|
Is the voltage 0.2 — 0.5 V? | |
| Yes | No |
|
|
Repair the harness and connector. NOTE: Repair the following locations. • Open circuit of harness between the ECM and rear oxygen sensor • Poor contact of the ECM and rear oxygen sensor • Poor contact in ECM connector |
