Possible causes

– Faulty electric throttle control actuator
– Throttle plate sticking due to carbon build-up
– Electric throttle control actuator harness is open or shorted
– Electric throttle control actuator poor electrical circuit connection
– Engine Control Module

When is the code detected?

The P2119 code is detected when electric throttle control actuator does not function properly due to the return spring malfunction or Engine Control Module (ECM) detect the throttle valve is stuck open.

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– No throttle pedal response

P2119 INFINITI Description

Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle control motor is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve.

The throttle position sensor detects the throttle valve position, and feeds the voltage signal to the ECM. The ECM judges the current opening angle of the throttle valve and controls the throttle valve opening angle in response to driving conditions via the throttle control motor.
