STEP | CHECK | YES | NO |
1.CHECK HARNESS BETWEEN ECM AND FRONT OXYGEN (A/F) SENSOR CONNECTOR.
1) Start and warm up the engine.
2) Turn the ignition switch to OFF.
3) Disconnect the connector from ECM.
4) Disconnect the connectors from front oxygen (A/F) sensor.
5) Measure the resistance of harness between ECM connector and front oxygen (A/F) sensor connector.
Connector & terminal
(B136) No. 5 — (E24) No. 1:
(B136) No. 19 — (E24) No. 3:
(B136) No. 18 — (E24) No. 4:
Is the resistance less than 1 ??
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0030 A/F / O2 HEATER CONTROL CIRCUIT BANK 1 SENSOR 1">Go to Step 2.
Repair the harness and connector.
NOTE:
In this case, repair the following item:
• Open circuit in harness between ECM connector and front oxygen (A/F) sensor connector
• Poor contact of coupling connector
2.CHECK FRONT OXYGEN (A/F) SENSOR.
Measure the resistance between front oxygen (A/F) sensor terminals.
Terminals
No. 1 — No. 2:
Is the resistance 2 — 3 ??
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0030 A/F / O2 HEATER CONTROL CIRCUIT BANK 1 SENSOR 1">Go to Step 3.
Replace the front oxygen (A/F) sensor. Front Oxygen (A/F) Sensor">
3.CHECK FOR POOR CONTACT.
Check for poor contact of ECM and front oxygen (A/F) sensor connector.
Is there poor contact of ECM or front oxygen (A/F) sensor connector?
Repair the poor contact of ECM or front oxygen (A/F) sensor connector.
Replace the front oxygen (A/F) sensor. Front Oxygen (A/F) Sensor">
1. OUTLINE OF DIAGNOSIS
Detect functional errors of the front oxygen (A/F) sensor heater.
Judge as NG when it is determined that the front oxygen (A/F) sensor impedance is large when looking at engine status such as deceleration fuel cut.
2. COMPONENT DESCRIPTION
(1) | Element cover (outer) | (3) | Sensor element | (4) | Sensor housing |
(2) | Element cover (inner) |
3. EXECUTION CONDITION
Secondary parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
A/F sensor heater control duty | > 17 % |
Elapsed time after fuel cut | ≥ 20000 ms |
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after 42000 ms seconds or more have passed since the engine started.
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 |
Front oxygen (A/F) sensor impedance | > 82 ? |
Time Needed for Diagnosis: 10000 ms
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
Switching power status
1. Apply the parking brake.
2. Shift the select lever into the "P"
position.
3. Depress the brake pedal.
