Detailed Manufacturer-Specific Explanations
Jaguar – ALTERNATOR/CHARING SYSTEM – LOAD CIRCUIT MALFUNCTION
For Jaguar, code P1632 is logged when the powertrain control module (PCM) has detected a circuit malfunction for the alternator system.
The alternator system converts some of the mechanical energy of the engine back to electrical energy. This is then used to power the various electrical systems in the car.
This can result in various electrical issues for the vehicle, including being unable to start due to a dead battery.
See generic codes: P0560 to P0563
Audi – ACCELERATOR PEDAL SENSOR
For Audi, P01632 is logged when the powertrain control module (PCM) has detected an issue with the accelerator pedal position (APP) sensor.
This happens when the supply voltage to the sensor is too low causing the sensor to malfunction.
The APP sensor is responsible for signaling the requested load to the PCM based on the position of the pedal.
A malfunctioning APP sensor means the PCM cannot accurately determine the speed at which the driver is aiming, which can be a serious issue.

BMW – THROTTLE VALVE ADAPTATION; ADAPTATION CONDITION NOT MET
For BMW, P1632 is logged when the powertrain control module (PCM) has detected an issue with the throttle valve.
This happens when the PCM cannot accurately read the position of the throttle body.
The PCM needs to know the position of the throttle to determine the load on the engine and the speed of the vehicle.
This fault code will usually result in the vehicle entering limp mode until it is resolved. This makes it very important to have this issue resolved immediately.
See generic codes: P0120 to P0124
Hyundai – TRACTION CONTROL SYSTEM – MALFUNCTION
For Hyundai, P1632 is logged when the powertrain control module (PCM) has detected an issue with the traction control system (TCS).
The TCS is a very important safety feature in modern cars. It ensures each wheel can grip the driving surface as best as possible. This helps maintain control of the vehicle, mostly when accelerating from a stop and on slippery surfaces.
To be able to properly function, the TCS needs to continuously send signals to the PCM about how the wheels are performing.

Kia – BATTERY VOLTAGE DETECTION CIRCUIT FOR ALTERNATOR REGULATOR
For Kia, P1632 is logged when the powertrain control module (PCM) has detected an issue with the battery voltage. This happens when a fault is found within the alternator circuit.
This fault code typically indicates an issue with the alternator circuit but can include issues with the battery.
The alternator is responsible for converting mechanical energy from the engine into electrical energy for the various electronic systems in a vehicle.
The alternator regulator controls the amount of power being sent from the alternator, ensuring the charging process is completed properly.
See generic codes: P0560 to P0563
Volkswagen – ACCELERATOR PEDAL POSITION SENSOR 1/2 SUPPLY VOLTAGE
For both Audi and Volkswagen, P632 represents the same issue. For more information on the problem and similar fault codes, see the above description for Audi.
