If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ab8 fault code. Here are the symptoms to look out for:

  • The P1AB8 fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting problems, decreased acceleration, and increased emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1AB8 automobile fault code can be caused by a faulty SGCM, openshorted harness, or poor electrical connection.

  • The automobile fault code P1AB8 can be caused by a faulty Starter/Generator Control Module (SGCM).
  • It can also be caused by an open or shorted SGCM harness.
  • Additionally, a poor electrical connection in the SGCM circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1ab8, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1ab8, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P1AB8 indicates an issue with the hybrid battery pack coolant pump. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the location of the repair shop, the severity of the issue, and the type of vehicle.

The P1AB8 fault code is related to the StarterGenerator Control Module (SGCM) phase UVW current sensors. These sensors are used for motor control and power inverter module (PIM) current sensor rationality check. The SGCM monitors the current sensor for failures in the UVW-phase current sensor circuit below or above the valid range.

The P1AB8 code specifically indicates a failure in the StarterGenerator Phase W Current Sensor Circuit, with high voltage being detected.

What are the possible causes of the P1AB8 fault code in an automobile?

If you see the engine light on or the service engine soon warning light in your automobile, it could be due to the P1AB8 fault code. This code is caused by a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit. To fix this issue, you should visually inspect the related 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 Starter/Generator Control Module (SGCM)?

If the engine light is on due to a faulty Starter/Generator Control Module (SGCM), it is important to visually inspect the related wiring harness and connectors. Check for any damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This can be done by carefully examining the wiring harness and connectors for any signs of wear and tear. It is also important to check for any open or shorted circuits and poor electrical connections. By doing so, you can identify the root cause of the problem and take the necessary steps to fix it.

What are the consequences of ignoring the P1AB8 fault code in an automobile?

Ignoring the P1AB8 fault code in an automobile, which indicates a faulty Starter/Generator Control Module (SGCM), can lead to serious consequences. The engine light will remain on, and the vehicle may not start or may stall while driving. It is crucial to inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins to fix the issue.
