| STEP | CHECK | YES | NO |
1.CHECK FRONT OXYGEN (A/F) SENSOR CONNECTOR AND COUPLING CONNECTOR.
Has water entered the connector?
Completely remove any water inside.
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0132 A/F / O2 SENSOR CIRCUIT HIGH VOLTAGE BANK 1 SENSOR 1">Go to Step 2.
2.CHECK HARNESS BETWEEN ECM AND FRONT OXYGEN (A/F) SENSOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from front oxygen (A/F) sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between ECM connector and chassis ground.
Connector & terminal
(B136) No. 18 (+) — Chassis ground (−):
(B136) No. 19 (+) — Chassis ground (−):
Is the voltage 8 V or more?
Repair the short circuit to power in the harness between ECM connector and front oxygen (A/F) sensor connector.
Replace the front oxygen (A/F) sensor. Front Oxygen (A/F) Sensor">
1. OUTLINE OF DIAGNOSIS
Detect the open or short circuit of sensor.
Judge as NG, when the element voltage is out of the specified range.
2. COMPONENT DESCRIPTION
(A) | Electromotive force | (B) | Air fuel ratio | (C) | Rich |
(D) | Lean | ||||
(1) | Exhaust gas | (2) | Zirconia element oxygen |
3. EXECUTION CONDITION
Secondary Parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
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 |
Input voltage (+) | > 4.7 V |
or | |
Input voltage (−) | > 4.7 V |
Time Needed for Diagnosis:
Input voltage (+): 1000 ms
Input voltage (−): 1000 ms
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
