If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the p1ac2 fault code. Here are the symptoms to look out for:

  • The P1AC2 fault code in an automobile 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 a loss of acceleration or have trouble shifting gears.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1AC2 fault code can be caused by a faulty control module, openshorted harness, or poor electrical connection.

  • The automobile fault code P1AC2 can be caused by a faulty Starter/Generator Control Module Cooling Fan Relay.
  • It can also be caused by an open or shorted Starter/Generator Control Module Cooling Fan Relay harness.
  • Additionally, a poor electrical connection in the Starter/Generator Control Module Cooling Fan Relay circuit can also trigger this fault code.

To fix the automobile fault code p1ac2, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p1ac2, 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 automobile fault code P1AC2 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 cost of fixing the P1AC2 fault code will be between $75 and $150, depending on the repair time required. It is important to consider these factors when seeking repairs for this fault code.

The P1AC2 fault code is related to the StarterGenerator Control Module (SGCM) in automobiles.

The SGCM controls the coolant fan operation by applying voltage to the coolant fan relay control circuit.

The SGCM monitors the relay control circuits for short to ground, short to voltage, or an open circuit.

If the SGCM detects an improper voltage level on the coolant fan relay control circuit, then DTC P1AC1 or P1AC2 will set and the driver will be disabled. The P1AC2 code indicates that there is a high voltage in the StarterGenerator Control Module Cooling Fan Relay Control Circuit.

What are the possible causes of the P1AC2 fault code?

If you’re experiencing the P1AC2 fault code, you may notice that your engine light is on. This could be due to a faulty Starter/Generator Control Module Cooling Fan Relay, an open or shorted harness, or a poor electrical connection in the circuit. To fix the issue, it’s recommended to visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can I visually inspect the wiring harness and connectors related to the Starter/Generator Control Module Cooling Fan Relay?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Starter/Generator Control Module Cooling Fan Relay. 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.
