  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • 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 P19FC automobile fault code can be caused by a range of issues, including a faulty relay, pump, harness, poor connection, or control module.

  • The automobile fault code P19FC can be caused by a faulty Starter/Generator Coolant Pump Relay.
  • It can also be caused by a faulty Starter/Generator Coolant Pump.
  • Another cause of this fault code is when the Starter/Generator Coolant Pump harness is open or shorted.
  • A poor electrical connection in the Starter/Generator Coolant Pump circuit can also trigger this fault code.
  • Lastly, a faulty Starter/Generator Control Module can cause the P19FC fault code to appear.

Below are the possible fixes for the automobile fault code p19fc, including inspecting wiring harness, connectors, and damaged components.

  • To fix the automobile fault code P19FC, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.

The automobile fault code P19FC 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 P19FC will be between $75 and $150, depending on the repair time required.

The P19FC code is related to the HybridEV Electronics Coolant Pump.

This pump circulates coolant through various components to control their temperature. The Enable and Feedback circuits allow the drive motor control module to control and monitor the pump.

The feedback circuit provides pump speed information during normal operation. If the pump detects an internal fault, it provides this information on the same feedback circuit instead of pump speed information. The DTC will be set if the Coolant Pump Feedback circuit indicated pump speed is greater than 225 RPM when the pump is not enabled.

What are the possible causes of the P19FC fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P19FC fault code. This code is caused by a faulty starter/generator coolant pump relay, a faulty starter/generator coolant pump, an open or shorted starter/generator coolant pump harness, a poor electrical connection in the starter/generator coolant pump circuit, or a faulty starter/generator control module. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors related to the Starter/Generator Coolant Pump?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) related to the Starter/Generator Coolant Pump, you may want to visually inspect the wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by a faulty Starter/Generator Coolant Pump Relay, faulty Starter/Generator Coolant Pump, Starter/Generator Coolant Pump harness being open or shorted, Starter/Generator Coolant Pump circuit poor electrical connection, or a faulty Starter/Generator Control Module. Check the “Possible Causes” listed above for a fix.

What are the consequences of not fixing the faulty Starter/Generator Coolant Pump Relay causing the P19FC fault code?

Ignoring the P19FC fault code caused by a faulty Starter/Generator Coolant Pump Relay can lead to serious consequences. The engine light or service engine soon warning light will remain on, indicating a problem with the vehicle’s starter and generator system. If left unaddressed, the faulty relay can cause damage to the starter and generator coolant pump, leading to costly repairs. It is important to check the possible causes listed above and visually inspect the related wiring harness and connectors to avoid further damage.
