STEP | CHECK | YES | NO |
1.CHECK HARNESS BETWEEN ECM AND FRONT OXYGEN (A/F) SENSOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Measure the voltage between ECM connector and chassis ground.
Connector & terminal
(B136) No. 5 (+) — Chassis ground (−):
Is the voltage 10 V or more?
Repair the short circuit to power in the harness between ECM connector and front oxygen (A/F) sensor connector.

2.CHECK GROUND CIRCUIT FOR ECM.
1) Disconnect the connector from ECM.
2) Measure the resistance between ECM connector and chassis ground.
Connector & terminal
(B134) No. 3 — Chassis ground:
(B134) No. 4 — Chassis ground:
(B136) No. 1 — Chassis ground:
(B136) No. 2 — Chassis ground:
(B136) No. 3 — Chassis ground:
Is the resistance less than 5 ??
Repair the poor contact of ECM connector.
Repair the harness and connector.
NOTE:
In this case, repair the following item:
• Open circuit of harness between ECM connector and engine ground
• Poor contact of coupling connector
1. OUTLINE OF DIAGNOSIS
Detect front oxygen (A/F) sensor heater open or short circuit.
The front oxygen (A/F) sensor heater performs duty control, and the output terminal voltage at ON is 0 V, and the output terminal voltage at OFF is the battery voltage.
Judge as NG when the terminal voltage remains High.
2. COMPONENT DESCRIPTION
(A) | Battery voltage | (B) | Front oxygen (A/F) sensor heater output voltage | (C) | 128 ms |
(D) | High error |
3. EXECUTION CONDITION
Secondary Parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
Primary oxygen sensor heater control duty | > 12.5 % |
4. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously.
5. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Malfunction Criteria | Threshold Value |
Measured primary oxygen sensor heater control voltage | ≥ 1.9 V |
Time Needed for Diagnosis: 2 seconds
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
