  • Additionally, the vehicle may experience transmission shifting issues, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1F45 fault code can be caused by a faulty or poorly connected HybridEV Electronics Coolant Pump or its harness.

  • The automobile fault code P1F45 can be caused by a faulty Hybrid/EV Electronics Coolant Pump.
  • It can also be caused by an open or shorted Hybrid/EV Electronics Coolant Pump harness.
  • Additionally, a poor electrical connection in the Hybrid/EV Electronics Coolant Pump circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p1f45, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1f45, 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 factors that influence the cost of diagnosing and fixing the automobile fault code P1F45 are: – The estimated repair time is 1.0 hour. – Auto repair shops usually charge between $75 and $150 per hour. – The cost may vary depending on the location and reputation of the repair shop.

– The cost may also depend on the severity of the issue and the parts that need to be replaced. – It is important to get a detailed estimate from the repair shop before proceeding with the repairs.

The P1F45 code is related to the hybridEV electronics coolant pump. This pump circulates coolant through the power electronics coolant radiator, hybridEV powertrain control module 1, and the battery charger.

The enable signal from the hybridEV powertrain control module 2 controls the pump. If the circuit is high, the pump can operate.

The pump speed is controlled by a pulse-width modulated signal from the hybridEV powertrain control module 2. The hybridEV electronics coolant pump provides a feedback signal to the hybridEV powertrain control module 2. If there is an internal fault, the pump provides this information on the feedback circuit instead of pump speed information.

What are the possible causes of the P1F45 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1F45 fault code.
