DTC P1705 THROTTLE POSITION SENSOR

PFP:22620

Description

ECS007NJ

●

Throttle position sensor
The throttle position sensor detects the throttle valve position
and sends a signal to the TCM.

●

Throttle position switch
Consists of a wide open throttle position switch and a closed
throttle position switch. The wide open position switch sends a
signal to the TCM when the throttle valve is open at least 1/2 of
the full throttle position. The closed throttle position switch sends
a signal to the TCM when the throttle valve is fully closed.
