id0102d2310800

DTC P0016:00 DTC P0018:00 | P0016:00: CKP-CMP sensor (RH) correlation P0018:00: CKP-CMP sensor (LH) correlation
--- | ---
DETECTION CONDITION | • The PCM monitors the variable valve timing position for a misalignment between the camshaft and crankshaft. The test fails when the misalignment is more than 1 tooth.
POSSIBLE CAUSE | • OCV malfunction • Camshaft advanced mechanism binding • Improper valve timing

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.
No | Record the 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.
No | Go to the next step.
3 | VERIFY RELATED PENDING AND STORED DTC • Turn the ignition switch off, then to the ON position (Engine off) • Verify pending and stored DTCs using M-MDS. • Is other DTC present? | Yes | Go to the appropriate DTC troubleshooting. (See DTC TABLE [MZI-3.7].)
No | P0016:00: • Go to the next step. P0018:00: • Go to Step 5.
4 | VERIFY OCV (RH) DRIVE CONDITION (P0016:00) • Turn the ignition switch off. • Disconnect the negative battery cable. • Disconnect the OCV (RH) connector. • Connect the negative battery cable. • Start the engine. • Access VT ACT1 PID using the M-MDS. • Record the PID [VT ACT1] value while idling. • Connect OCV (RH) terminal A to positive battery terminal. • Connect OCV (RH) terminal B to the negative battery terminal using a jumper wire at the timing of 20 times or more for 20 s. • Connect OCV (RH) terminal B to the negative battery terminal using a jumper wire to maintain the drive condition. Note • Release the jumper wire immediately after verifying the value. • Did the PID [VT ACT1] change 20 ° or more? | Yes | Go to Step 8.
No | Go to Step 6.
5 | VERIFY OCV (RH) DRIVE CONDITION (P0018:00) • Turn the ignition switch off. • Disconnect the negative battery cable. • Disconnect the OCV (LH) connector. • Connect the negative battery cable. • Start the engine. • Access VT ACT2 PID using the M-MDS. • Connect the following terminals using a jumper wire and verify the PID [VT ACT2] behavior. ― OCV (LH) terminal A—Positive terminal ― OCV (LH) terminal B—Negative terminal • Did the PID [VT ACT2] change 20 ° or more? | Yes | Go to Step 8.
No | Go to the next step.
6 | INSPECT ENGINE OIL PRESSURE • Inspect the engine oil pressure. (See OIL PRESSURE INSPECTION [MZI-3.7].) • Is there any malfunction? | Yes | Repair or replace the malfunctioning part according to the inspection results, then go to Step 10.
No | Go to the next step.
7 | INSPECT OCV P0016:00: • Inspect the OCV (RH). (See OIL CONTROL VALVE (OCV) INSPECTION [MZI-3.7].) P0018:00: • Inspect the OCV (LH). (See OIL CONTROL VALVE (OCV) INSPECTION [MZI-3.7].) • Is there any malfunction? | Yes | Replace the OCV, then go to Step 6. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [MZI-3.7].)
No | Go to the next step.
8 | 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.
No | Reinstall the timing chain, then go to Step 10.
9 | VERIFY VARIABLE VALVE TIMING ACTUATOR OPERATION • Access VT DIFF1 and VT DIFF2 PIDs using the M-MDS. P0016: • Does VT DIFF2 PID remain approx. 0 ° and is VT DIFF1 PID greater than 0.05 °? P0018: • Does VT DIFF1 PID remain approx. 0 ° and is VT DIFF2 PID greater than 0.05 °? | Yes | Replace the suspect variable valve timing actuator, then go to the next step. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [MZI-3.7].)
No | Go to the next step.
10 | VERIFY TROUBLESHOOTING OF DTC P0016:00, P0018:00 HAS BEEN COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the engine switch to the ON position. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • Is the same 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.
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].)
No | Troubleshooting completed.
