P1126 INFINITI – Open Throttle Control Motor Relay Circuit

P1126 INFINITI Possible Causes

• Faulty throttle control motor relay
• Throttle control motor relay harness is open or shorted
• Poor electrical connection in the throttle control motor relay circuit

How to Fix P1126 INFINITI Code?

Start by checking the “possible causes” listed above. Visually inspect the corresponding cable harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

 

 

When is the Code Detected?

The Engine Control Module (ECM) detects that a voltage from the power supply for the throttle control motor is excessively low.

Possible Symptoms

• Engine light on (or engine service warning light soon)

P1126 INFINITI Meaning

 

The throttle control motor power supply is provided to the Engine Control Module (ECM) via the throttle control motor relay. The throttle control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends an ON signal to the throttle control motor relay and battery voltage is supplied to the ECM. When the ignition switch is OFF, the ECM sends an OFF signal to the throttle control motor relay and battery voltage is not supplied to the ECM.
