P1125 CADILLAC Possible Causes

• Faulty accelerator pedal position sensor

  Poor electrical connection in accelerator pedal position sensor circuit

How to Fix P1125 CADILLAC Code?

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

When is the Code Detected?

The Powertrain Control Module (PCM) detects that the difference between accelerator pedal position sensor 1 (APP) and APP sensor 2 is greater than the expected value.

Possible Symptoms

Illuminated engine light (or service engine soon warning light)

P1125 CADILLAC Meaning

The accelerator pedal position sensor 1 (APP) and APP sensor 2 are potentiometer-type sensors, each with the following circuits:
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
The control module provides the APP sensors with a 5-volt reference circuit and a low reference circuit. The APP sensors then provide the control module with signal voltages proportional to pedal movement. The signal voltage from APP sensor 1 is low at rest and increases when the pedal is depressed.
The signal voltage from APP sensor 2 is low at rest and increases when the pedal is depressed. When the control module detects that the signal circuits of APP sensor 1 and APP sensor 2 do not correlate with each other, DTC P1125 is set.

P1125 FORD Meaning

The Throttle Position Sensor (TPS) responds to the accelerator pedal movement. The TPS is a rotary potentiometer sensor that provides a signal to the Powertrain Control Module (PCM) that is linearly proportional to the throttle plate/shaft position. As the TPS is rotated by the throttle shaft, the following operating conditions are determined by the PCM:

• Closed throttle (includes idle or deceleration)
• Part throttle (includes cruise or moderate acceleration)
• Wide open throttle (includes maximum acceleration or crank flare)
• Throttle angle rate

P1125 LEXUS Meaning

The throttle motor is actuated by the ECM and it opens and closes the throttle valve.
The throttle valve opening angle is detected by the throttle position sensor mounted on the throttle body and it provides feedback to the ECM to control the throttle motor so that the throttle valve opening angle is properly responsive to driving conditions.
If this DTC is stored, the ECM cuts power to the throttle motor and magnetic clutch, and the throttle valve is completely closed by the return spring.
However, the throttle valve opening angle can be controlled by the accelerator pedal via the throttle cable
