DTC P0010:00 [MZI-3.7]

id0102d2310700

DTC P0010:00

OCV (RH) circuit open

DETECTION CONDITION

•  The PCM monitors the OCV (RH) circuit to the PCM for high and low voltage. The test fails if the voltage exceeds or falls below a calibrated limit for a calibrated amount of time.

POSSIBLE CAUSE

•  Connector or terminal malfunction

•  OCV (RH) malfunction

•  Open circuit between OCV (RH) terminal A and main relay No.1 terminal D

•  Short to power supply between OCV (RH) terminal B and PCM terminal 2BP

•  Short to ground circuit between OCV (RH) terminal B and PCM terminal 2BP

•  Open circuit between OCV (RH) terminal B and PCM terminal 2BP

DTC P0010:00	OCV (RH) circuit open
DETECTION CONDITION	• The PCM monitors the OCV (RH) circuit to the PCM for high and low voltage. The test fails if the voltage exceeds or falls below a calibrated limit for a calibrated amount of time.
POSSIBLE CAUSE	• Connector or terminal malfunction • OCV (RH) malfunction • Open circuit between OCV (RH) terminal A and main relay No.1 terminal D • Short to power supply between OCV (RH) terminal B and PCM terminal 2BP • Short to ground circuit between OCV (RH) terminal B and PCM terminal 2BP • Open circuit between OCV (RH) terminal B and PCM terminal 2BP

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME DATA 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 OCV (RH) CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the OCV (RH) connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 10.
3		No	Go to the next step.
4	INSPECT OCV (RH) • Inspect the OCV (RH). (See OIL CONTROL VALVE (OCV) INSPECTION [MZI-3.7].) • Is there any malfunction?	Yes	Replace the OCV (RH), then go to Step 10. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [MZI-3.7].)
4		No	Go to the next step.
5	INSPECT OCV (RH) CIRCUIT FOR OPEN CIRCUIT • OCV (RH) connector is disconnected. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the OCV (RH) connector terminal A (wiring harness-side) and body ground. • Is the voltage B+?	Yes	Go to the next step.
5		No	Repair or replace suspected part, then go to Step 10.
6	INSPECT OCV (RH) CIRCUIT FOR SHORT TO POWER SUPPLY • OCV (RH) connector is disconnected. • Turn the ignition switch off. • Disconnect the PCM connector. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the OCV (RH) connector terminal B (wiring harness-side) and body ground. • Is the voltage B+?	Yes	Repair or replace suspected part, then go to Step 10.
6		No	Go to the next step.
7	INSPECT OCV (RH) CIRCUIT FOR SHORT TO GROUND • OCV (RH) and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between OCV (RH) terminal B (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace suspected part, then go to Step 10.
7		No	Go to the next step.
8	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/ pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace suspected part, then go to Step 10.
8		No	Go to the next step.
9	INSPECT OCV (RH) CIRCUIT FOR OPEN CIRCUIT • OCV (RH) and PCM connectors are disconnected. • Turn the ignition switch off. • Measure the resistance between the OCV (RH) connector terminal B (wiring harness-side) and PCM terminal 2BP (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace suspected part, then go to the next step.
10	VERIFY TROUBLESHOOTING OF DTC P0010:00 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the M-MDS. • Start the engine and run it at idle. • Retrieve DTCs using the M-MDS. • Is the PENDING CODE for this DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
11		No	Troubleshooting completed.
