P1630 - FAULT CODE - OBD2

P1630 AUDI, VOLKSWAGEN: ACCELERATOR PEDAL POSITION SENSOR 1 LOW INPUT

To control modern accelerator systems, manufacturers design electronic systems, which include an actuator, a motor, and various sensors. All these components together collect information that is provided to the ECM (Engine Control Module), the module in charge of managing when the throttle is closed or opened.

In the case of the Accelerator Pedal Position (APP Sensor), it is an electronic device located on the accelerator pedal. It detects in which position the pedal is located and, based on this position, informs the ECM through an electrical signal. The ECM, taking this data into account, will adjust the pedal angle.

When the diagnostic code P1630 OBDII is stored in Audi and Volkswagen vehicles, it is because the Accelerator Pedal Position Sensor 1 has experienced a malfunction. The code specifically states that the input signal from this sensor is excessively low.

• Check Engine lamp illuminated.
• Loss of throttle control.

DTC P1630 OBD2 is set for one of the following reasons:

• The Accelerator Pedal Position Sensor 1 may have deficiencies in its wiring.
• The APP sensor 1 circuit may have deficiencies in the electrical connections.
• The Accelerator Pedal Position Sensor 1 may be faulty.

To troubleshoot the P1630 OBDII fault code you must do the following:

• Consult the TSB.
• Check that all APP Sensor 1 wires comply with the conditions for good sensor performance. If you detect common deficiencies such as corrosion or wear, make the appropriate repairs.
• Use the appropriate tools to measure the Accelerator Pedal Position Sensor 1 circuit voltages to rule out a short open circuit. If such conditions are detected, make corrections accordingly.
• Verify the integrity of the Accelerator Pedal Position Sensor 1 using the manufacturer's guidelines. If you determine that it is defective, replace it.
