DTC Description

DTC DETECTION LOGIC

DTC No.	CONSULT screen terms (Trouble diagnosis content)	DTC detecting condition
P1290	ETC MOT PWR-B2 [Throttle control motor relay circuit open (bank 2)]	ECM detects a voltage of power source for throttle control motor is excessively low.

POSSIBLE CAUSE

DTC P1290

Harness or connectors (Throttle control motor relay circuit is open)

FAIL-SAFE

Fail safe mode	Vehicle behavior
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.
Others	The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. So, the acceleration will be poor.
