DTC Description

DTC DETECTION LOGIC 

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P010C-00	MAF SEN/CIRCUIT-B2 (Mass or volume air flow "B" circuit low input)	Diagnosis condition	-
		Signal (terminal)	Mass air flow sensor (bank 2) signal
		Threshold	An excessively low frequency from the sensor is sent to ECM
		Diagnosis delay time	-

POSSIBLE CAUSE 

• Harness or connectors [The mass air flow sensor (bank 2) circuit is open or shorted.]
• Mass air flow sensor (bank 2)

FAIL-SAFE 

Engine Control System 

Fail safe mode		Vehicle behavior
Traveling control mode	Accelerator angle variation control	ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction. NOTE: ECM does not control the accelerator pedal releasing speed.
	Engine output control	ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle speed to encourage the driver to repair malfunction. Driving at 70 km/h (44 MPH) or more is possible. NOTE: This value is a reference value converted from engine power to vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
Device fix mode		Fixes electric intake valve timing control motor in the reference position. Fixes exhaust valve timing control solenoid valve in the reference position. The Intake manifold runner control valve motor is turned OFF (Intake manifold runner control valve opens).
Combustion control mode	Stratified charge combustion control at starting	No stratified charge combustion at starting (cold start).
	Idle speed control	Stops feedback control of idle speed and controls with specified speed.
	Recovery speed control at decelerating	Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.
	Ignition timing correction control	Partially controls ignition timing control.
	Retardation control	Controls ignition timing delay control in the intermediate water temperature range.

DTC CONFIRMATION PROCEDURE 

1. PRECONDITIONING 

   If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

   1. Turn ignition switch OFF and wait at least 10 seconds.
   2. Turn ignition switch ON.
   3. Turn ignition switch OFF and wait at least 10 seconds.

   GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE 
   1. Start engine and wait at least 5 seconds.
   2. Check DTC.
