If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ffd fault code.

Here are the symptoms to look out for:

  • The P1FFD 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, engine misfires, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1FFD automobile fault code can be caused by various issues, including a faulty powertrain control module or poor electrical connections.

  • The automobile fault code P1FFD can be caused by a faulty Hybrid/EV Powertrain Control Module 2.
  • It can also be caused by an open or shorted Hybrid/EV Powertrain Control Module 2 harness.
  • Additionally, a poor electrical connection in the Hybrid/EV Powertrain Control Module 2 circuit can also trigger this fault code.

To fix the p1ffd automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p1ffd, you need to check the possible causes listed above.
  • 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 P1FFD has an estimated repair time of 1.0 hour.

The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop.

The cost may also vary based on the severity of the issue and the type of vehicle.

It is important to note that the cost of fixing this fault code may increase if additional repairs are needed.

The P1FFD code is related to the hybridEV battery pack coolant system.

It indicates that there is a high voltage in the hybridEV battery pack coolant level sensor circuit.

The sensor is a 2 state bi-metallic reed switch that changes state when exposed to magnetism. The powertrain control module 2 supplies 5V to the signal circuit and a ground for the low reference circuit. The resistance of the sensor decreases when the battery coolant level in the surge tank gets low.

The powertrain control module 2 uses the sensor to determine if the hybridEV battery pack coolant system is low on coolant.

What are the possible causes of the P1FFD fault code?

If you’re experiencing the P1FFD fault code, you may notice that your engine light is on. This could be due to a faulty Hybrid/EV Powertrain Control Module 2, 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. Additionally, check for broken, bent, or pushed out connector pins.
