[SOLVED] P1Ab5 Code: Low Voltage In Starter/Generator Phase V – Fix Now!

The P1AB5 automobile fault code indicates a problem with the StarterGenerator Control Module (SGCM).

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 SGCM, an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit.

It is important to address this issue promptly as it can lead to further damage to the vehicle.

The repair time for this issue is estimated to be around 1.0 hour.

To fix this problem, 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.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ab5 fault code. Here are the symptoms to look out for:

  • The P1AB5 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 P1AB5 fault code can be caused by a faulty SGCM, openshorted harness, or poor electrical connection.

  • The automobile fault code P1AB5 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 Starter/Generator Control Module (SGCM) circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1ab5, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1ab5, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for 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 is P1AB5. The estimated repair time is 1.0 hour. The cost of fixing the issue is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour.

Therefore, the cost of fixing the P1AB5 fault code will be between $75 and $150.

The P1AB5 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 P1AB5 code specifically indicates a failure in the StarterGenerator Phase V Current Sensor Circuit, with low voltage being detected.

What are the possible causes of the P1AB5 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 P1AB5 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 could be caused by an open or shorted 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 P1AB5 fault code in an automobile?

Ignoring the P1AB5 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.
