DTC P0022:00 [MZI-3.7]

id0102d2311100

DTC P0022:00

CMP timing over-retarded (LH)

DETECTION CONDITION

•  The PCM monitors the variable valve timing position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.

POSSIBLE CAUSE

•  Low engine oil pressure

•  Spool valve in the OCV (LH) is stuck in retard position

•  Improper valve timing due to timing chain slippage

•  OCV (LH) malfunction

DTC P0022:00	CMP timing over-retarded (LH)
DETECTION CONDITION	• The PCM monitors the variable valve timing position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.
POSSIBLE CAUSE	• Low engine oil pressure • Spool valve in the OCV (LH) is stuck in retard position • Improper valve timing due to timing chain slippage • OCV (LH) malfunction

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	VERIFY ENGINE OIL PRESSURE • Start the engine. • Does the oil pressure warning light illuminate?	Yes	Inspect the engine oil pressure, then go to Step 6. (See OIL PRESSURE INSPECTION [MZI-3.7].)
3		No	Go to the next step.
4	VERIFY TIMING CHAIN INSTALLATION • Stop the engine. • Remove the front cover. • Is the camshaft timing mark at the correct point? (See TIMING CHAIN REMOVAL/INSTALLATION [MZI-3.7].)	Yes	Go to the next step.
4		No	Reinstall the timing chain, then go to Step 6.
5	INSPECT OCV (LH) • Inspect the OCV (LH). (See OIL CONTROL VALVE (OCV) INSPECTION [MZI-3.7].) • Is there any malfunction?	Yes	Replace the OCV (LH), then go to the next step.
5		No	Go to the next step.
6	VERIFY TROUBLESHOOTING OF DTC P0022:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Turn the ignition switch off. • Start the engine and warm it up completely. • 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.
6		No	Go to the next step.
7	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].)
7		No	Troubleshooting completed.
