Retarded timing over
(Valve timing is out of specified range)P0012

If DTC ºP0011 or P0012º is displayed, check VVT system circuit.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for deter\
mining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ra\
tio was lean or rich, etc. at
the time of the malfunction.

2 PERFORM ACTIVE TEST BY HAND±HELD TESTER(OPERATE OCV)
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and warm it up.
(c) Turn the ignition switch ON and push the hand±held tester main switch ON.
(d) Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TEST / VVT CTRL B1º.
(e) Check the engine speed when operating the OCV by the hand±held tester.
Standard:

OCV is OFFNormal engine speed
OCV is ONRough idle or engine stall
NG Go to step 4
OK
3 CHECK IF DTC OUTPUTS REOCCUR
(a) Clear the DTC.
(1) Operating the hand±held tester to erase the codes, or disconnecting the battery terminal or the
EFI and ETCS fuses for 60 seconds or more.
(b) Start the engine and warm it up.
(c) Drive the vehicle around for 10 minutes or more.
(d) Read output DTC using the hand±held tester.
Standard: No DTC output.
HINT:
*: DTCs P0011 or P0012 is output when a foreign object in engine oil is caught in some part of the system.
These codes will stay registered even if the system returns to normal after a short time. These foreign objects
are then captured by the oil filter, thus eliminating the source of the problem.
