If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1e8d fault code.

Here are the symptoms to look out for:

  • The P1E8D 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 vehicle.
  • Additionally, the code may cause issues with the transmission, such as harsh shifting or failure to shift gears properly.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1E8D fault code can be caused by a faulty or poorly connected HybridEV Battery Pack Coolant Pump or its harness.

  • The automobile fault code P1E8D can be caused by a faulty Hybrid/EV Battery Pack Coolant Pump.
  • It can also be caused by an open or shorted Hybrid/EV Battery Pack Coolant Pump harness.
  • Additionally, a poor electrical connection in the Hybrid/EV Battery Pack Coolant Pump circuit can also trigger this fault code.

To fix the p1e8d automobile fault code, check the possible causes and inspect the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1e8d, 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 P1E8D 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 the P1E8D fault code will depend on the hourly rate charged by the auto repair shop.

The P1E8D code is related to the hybridEV battery pack coolant pump. This code indicates that the enable circuit for the pump is experiencing high voltage.

The hybridEV powertrain control module 2 controls the pump with a pulse-width modulated signal. The pump provides feedback to the control module with a hard-wired pulse-width modulated signal. If the pump detects an internal fault, it will provide this information on the feedback circuit instead of pump speed information.

What are the possible causes of the P1E8D automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1E8D fault code. This code is usually caused by a faulty Hybrid/EV Battery Pack Coolant Pump, an open or shorted Hybrid/EV Battery Pack Coolant Pump harness, or a poor electrical connection in the Hybrid/EV Battery Pack Coolant Pump 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 I visually inspect the wiring harness and connectors related to the Hybrid/EV Battery Pack Coolant Pump?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Hybrid/EV Battery Pack Coolant Pump, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Hybrid/EV Battery Pack Coolant Pump harness is open or shorted, or if the Hybrid/EV Battery Pack Coolant Pump circuit has a poor electrical connection.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection of the P1E8D fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection of the P1E8D fault code, you should visually inspect the related wiring harness and connectors. Check for any possible causes listed above and fix them accordingly. It is important to ensure that the Hybrid/EV Battery Pack Coolant Pump harness is not open or shorted and that the Hybrid/EV Battery Pack Coolant Pump circuit has a good electrical connection.
