Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) Click here.
Turn the power switch off.
Turn the power switch on (IG) and turn the tester on [A].
Put the engine in inspection mode Click here.
Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or more [B].
Idle the engine for 5 minutes or more [C].
Enter the following menus: Powertrain / Engine and ECT / DTC / Pending [D].
Read the pending DTC.
If a pending DTC is output, the system is malfunctioning.

Tech Tips

If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Input the DTC: P0016 or P0018.

Check the DTC judgment result.

Tester Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions
UNKNOWN	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU's memory limit

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Tech Tips

If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [E] through [G].

Drive the vehicle for 2 to 3 minutes [E].
Idle the engine for 5 minutes or more [F].
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Input the DTC: P0016 or P0018.
Check the DTC judgment result again [G].

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 OR P0018)

Connect the intelligent tester to the DLC3.
Turn the power switch on (IG).
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / DTC.

Read the DTCs.

Result

Result	Proceed to
DTC P0016 or P0018 is output	A
DTC P0016 or P0018 and other DTCs are output	B

Tech Tips

If any DTCs other than P0016 or P0018 are output, troubleshoot those DTCs first.

*1 Timing Mark

Remove the cylinder head cover sub-assemblies RH and LH.
Turn the crankshaft to align the timing marks of the crankshaft.
Align the notch of the crankshaft pulley to the "0" position.
Check if the timing marks of the camshaft pulley and camshaft bearing cap align.

*1	Timing Mark

Turn the crankshaft clockwise 360° if the timing marks do not align. Check if they align once again.

OK
The timing marks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.

Reinstall the cylinder head cover sub-assemblies RH and LH.

DTC is not output	A
DTC P0016 or P0018 is output	B

Tech Tips

DTC P0016 or P0018 is output when foreign objects in engine oil are caught in some parts of the system. These codes will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter, thus eliminating the source of the problem.
