If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a9c fault code. Here are the symptoms to look out for:

  • The P1A9C 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, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1A9C fault code in automobiles can be caused by various factors, including a faulty SGCM or poor electrical connection.

  • The automobile fault code P1A9C 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 p1a9c automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p1a9c, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1A9C has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of P1A9C will be between $75 and $150, depending on the repair time required.

The P1A9C fault code is related to the StarterGenerator Inverter Phase U Temperature Sensor Circuit.

The Power Inverter Module (PIM) temperature sensors are used for overheat protection.

The thermistors are located on the control board, near the phase U or V power MOSFET. The StarterGenerator Control Module (SGCM) monitors the inverter temperature sensor for detecting if the inverter phase U or V temperature sensor is shorted low or high.

The P1A9C code indicates that the inverter phase U temperature sensor circuit is experiencing low voltage.

What are the possible causes of the P1A9C fault code in an automobile?

If you’re experiencing the P1A9C fault code in your automobile, you may notice that the engine light is on or the service engine soon warning light is illuminated. This fault code is typically 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 the issue, it’s important to 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 P1A9C fault code in an automobile?

Ignoring the P1A9C 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.
