Details On DTCs

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

DESCRIPTION	Electric variable valve timing control system: P0011:00: Over-advanced P0012:00: Over-retarded
DETECTION CONDITION	Determination conditions	P0011:00: A condition in which the actual intake valve timing advances (excess advance) compared to the target intake valve timing continues for the specified period.
	Determination conditions	P0012:00: A condition in which the actual intake valve timing retards (excess retard) compared to the target intake valve timing continues for the specified period.
	Preconditions	Battery voltage: above 11 V ^1 Engine speed: 5, 000 rpm or less ^1 Engine coolant temperature: 20 °C {68 °F} or more ^1 The following DTCs are not detected: P0010:00, P0335:00, P0340:00 ^1 : Value can be verified by displaying PIDs using M-MDS
	Malfunction determination period	10 s period
	Drive cycle	1
	Self test type	CMDTC self test
	Sensor used	CKP sensor Intake CMP sensor
FAIL-SAFE FUNCTION	Not applicable
VEHICLE STATUS WHEN DTCs ARE OUTPUT	Illuminates check engine light.
POSSIBLE CAUSE	Electric variable valve timing motor/driver connectors or terminals malfunction Short to ground or open circuit in electric variable valve timing relay power supply circuit Short to ground in wiring harness between battery positive terminal and electric variable valve timing relay terminal D MAIN 200 A fuse and/or EVVT 20 A fuse malfunction Open circuit in wiring harness between battery positive terminal and electric variable valve timing relay terminal D Short to ground in wiring harness between the following terminals: Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 1E Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 2B Open circuit in wiring harness between the following terminals: Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 1E Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 2B PCM connector or terminals malfunction Electric variable valve timing relay malfunction Electric variable valve timing motor malfunction Electric variable valve timing actuator malfunction Electric variable valve timing actuator is stuck in advanced position Electric variable valve timing actuator is stuck in retarded position Timing chain malfunction Poor assembly of timing chain Looseness or jumping Mis-detection of intake CMP sensor Mis-detection of CKP sensor PCM malfunction
