The automobile fault code P1122 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

Most auto repair shops typically charge between $75 and $150 per hour for their services.

The P1122 fault code refers to a problem with the Throttle Position Sensor (TPS) circuit.

The TPS is responsible for detecting the position and speed of the throttle valve in the Electric Throttle Control Actuator. It sends voltage signals to the Engine Control Module (ECM) to determine the current opening angle of the throttle valve. When the ECM receives intermittent low voltage signals from the TPS circuit, it triggers the P1122 fault code.

This means that there is a problem with the TPS circuit, causing the voltage signals to drop below the expected range. To fix this issue, the TPS circuit needs to be inspected and repaired. This may involve checking the wiring connections, testing the TPS for proper functionality, and replacing any faulty components.

It is important to address this fault code promptly to ensure proper throttle control and optimal engine performance.
