  • The P1AB1 fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P1AB1 automobile fault code can be caused by various factors, including a faulty SGCM or poor electrical connection.

  • The automobile fault code P1AB1 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.

To fix the p1ab1 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1ab1, 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 factors that influence the cost of fixing the automobile fault code P1AB1 are the estimated repair time and the hourly rate charged by the auto repair shop.

The estimated repair time for this fault code is 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

These factors should be considered when estimating the cost of fixing the P1AB1 fault code.

The P1AB1 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 below or above the valid range. The P1AB1 code specifically indicates an overcurrent in the StarterGenerator Phase U-V-W Current Sensor.

What are the possible causes of the P1AB1 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 P1AB1 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) to fix the P1AB1 fault code?

If you’re experiencing the P1AB1 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, it could be due to 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.

What are the symptoms of the P1AB1 fault code in an automobile, and how can one identify them?

The P1AB1 fault code in an automobile is identified by the engine light turning on or the service engine soon warning light. The cause of this fault code is 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, one 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.
