If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a88 fault code. Here are the symptoms to look out for:

  • The P1A88 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, 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 P1A88 fault code in automobiles can be caused by a faulty APM, openshorted harness, or poor electrical connection.

  • The automobile fault code P1A88 can be caused by a faulty Accessory DC Power Control Module (APM).
  • It can also be caused by an open or shorted harness of the Accessory DC Power Control Module (APM).
  • Additionally, a poor electrical connection in the Accessory DC Power Control Module (APM) circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1a88, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1A88, 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 automobile fault code P1A88 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the P1A88 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P1A88 fault code relates to the Accessory DC Power Control Module (APM) in a hybrid vehicle. The APM supplies energy between the high voltage, 300 volt, Direct Current (DC) and intermediate voltage, 42 volt, DC to support the Electric Power Steering (EPS). The APM continuously monitors the status of its 42 volt circuitry and runs diagnostics on it when the ignition key is first turned to RUN.

The P1A88 code indicates a problem with the 42 volt system performance and may require further diagnosis and repair.

What are the possible causes of the P1A88 fault code in an automobile?

If you’re experiencing the P1A88 fault code in your automobile, you may notice that the engine light is on or the service engine soon warning light is illuminated.
