If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ab7 fault code.

Here are the symptoms to look out for:

  • The P1AB7 fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P1AB7 fault code can be caused by a faulty SGCM, openshorted harness, or poor electrical connection.

  • The automobile fault code P1AB7 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 p1ab7, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1ab7, 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 P1AB7 is a common issue in automobiles. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code is dependent on the repair time.

Most auto repair shops charge between $75 and $150 per hour. Therefore, the cost of fixing the P1AB7 fault code can range from $75 to $150.

It is important to consider the repair time and the hourly rate when estimating the cost of fixing this fault code.

The P1AB7 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 P1AB7 code specifically indicates a failure in the StarterGenerator Phase W Current Sensor Circuit, with low voltage being detected.

What are the possible causes of the P1AB7 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 P1AB7 fault code. This code is usually 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 could be caused by an open or shorted SGCM harness or a poor electrical connection in the SGCM circuit. To fix the issue, check the possible causes listed above and address any issues found during the visual inspection.

What are the consequences of ignoring the P1AB7 fault code in an automobile?

Ignoring the P1AB7 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 address the issue immediately by visually inspecting the wiring harness and connectors and checking for damaged components to avoid further damage.
