[SOLVED] P1Aba Code: High Voltage In Starter/Generator Field Coil Circuit

The P1ABA fault code in automobiles indicates a problem with the Motor Generator Unit (MGU). The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty MGU, an open or shorted MGU harness, or a poor electrical connection in the MGU circuit. The importance of repairing this issue lies in the fact that it affects the performance of the vehicle.

The difficulty level of repairing this fault code is moderate, and it takes approximately 1.0 hour to fix. To fix the issue, one needs to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. It is essential to interpret the fault code correctly to identify the problem and fix it accordingly.

The automobile fault code P1ABA has an estimated repair time of 1.0 hour. The cost of fixing this code can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. These factors can influence the overall cost of diagnosing and fixing the P1ABA fault code.

The P1ABA fault code is related to the StarterGenerator Control Module (SGCM) in an automobile.

It indicates that the Motor Generator Unit (MGU) field coil circuit is being monitored by the SGCM.

The fault code is triggered when the SGCM detects that the field coil current is higher than the acceptable range. This fault code is specifically related to the StarterGenerator Field Coil Current Sensor Circuit High Voltage.

It is important to address this issue promptly to avoid further damage to the vehicle’s electrical system.

What are the possible causes of the P1ABA fault code in an automobile?

If you see the engine light on or the service engine soon warning light, it could be due to the P1ABA fault code. This code is usually caused by a faulty Motor Generator Unit (MGU), an open or shorted MGU harness, or a poor electrical connection in the MGU circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the wiring harness and connectors related to the Motor Generator Unit (MGU) to fix the P1ABA fault code?

If you’re experiencing the P1ABA fault code, indicated by the engine light or service engine soon warning light being on, it may be due to a faulty Motor Generator Unit (MGU), an open or shorted MGU harness, or poor electrical connection in the MGU circuit. To fix this issue, visually inspect the wiring harness and connectors related to the MGU. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P1ABA fault code in an automobile?

Ignoring the P1ABA fault code in an automobile can lead to serious consequences. The engine light will remain on, indicating a problem with the Motor Generator Unit (MGU) or its circuit. This fault code can be caused by a faulty MGU, an open or shorted MGU harness, or a poor electrical connection. To fix the issue, it is important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
