The P1126 fault code refers to a problem with the throttle control motor relay circuit. This circuit is responsible for providing power to the throttle control motor, which is controlled by the Engine Control Module (ECM).

When the ignition switch is turned on, the ECM sends a signal to the throttle control motor relay, allowing battery voltage to be provided to the ECM. However, when the ignition switch is turned off, the ECM sends a signal to the relay to turn it off, cutting off battery voltage to the ECM. This fault code indicates an issue with this circuit, which may result in problems with the throttle control motor and its operation.
