DTC P0130:00

A/F sensor circuit problem

DETECTION CONDITION

•  If the A/F sensor electrical resistance is 500 ohms or more for 2 s or more even though the A/F sensor heater is operated.

Diagnostic support note

•  This is an intermittent monitor (A/F sensor, HO2S).

•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.

•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  A/F sensor connector or terminals malfunction

•  PCM connector or terminals malfunction

•  A/F sensor malfunction

•  Following wiring harness deterioration

―  A/F sensor terminal A and PCM terminal 2Z

―  A/F sensor terminal B and PCM terminal 2AD

•  PCM malfunction

DTC P0130:00	A/F sensor circuit problem
DETECTION CONDITION	• If the A/F sensor electrical resistance is 500 ohms or more for 2 s or more even though the A/F sensor heater is operated. Diagnostic support note • This is an intermittent monitor (A/F sensor, HO2S). • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• A/F sensor connector or terminals malfunction • PCM connector or terminals malfunction • A/F sensor malfunction • Following wiring harness deterioration ― A/F sensor terminal A and PCM terminal 2Z ― A/F sensor terminal B and PCM terminal 2AD • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED • Have the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS (A/F sensor, HO2S related) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT A/F SENSOR CONNECTOR AND TERMINALS • Turn the ignition switch off. • Disconnect the A/F sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 6.
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR AND TERMINALS • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 6.
4		No	Go to the next step.
5	INSPECT A/F SENSOR • Reconnect the A/F sensor and PCM connectors. • Inspect the A/F sensor. (See AIR FUEL RATIO (A/F) SENSOR INSPECTION [ZJ, ZY].) • Is there any malfunction?	Yes	Replace the A/F sensor, then go to the next step. (See AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [ZJ, ZY].)
5		No	Inspect the wiring harness between the following terminals for deterioration. • A/F sensor terminal A and PCM terminal 2Z • A/F sensor terminal B and PCM terminal 2AD Repair or replace the suspected wiring harness, if necessary. Go to the next step.
6	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [ZJ, ZY].) • Perform the KOEO/KOER self test. (See KOEO/KOER SELF TEST [ZJ, ZY].) • Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [ZJ, ZY].)
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [ZJ, ZY].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ZJ, ZY].)
7		No	DTC troubleshooting completed.
