If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p19fa fault code. Here are the symptoms to look out for:

  • The P19FA 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, 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 P19FA 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 P19FA 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 P19FA fault code to appear.

Below are the possible fixes for the automobile fault code: p19fa, including inspecting wiring harness, connectors, and damaged components.

  • To fix the automobile fault code P19FA, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look 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 P19FA has an estimated repair time of 1.0 hour. The cost of fixing this fault code varies depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

These factors are influential in determining the overall cost of diagnosing and fixing the P19FA fault code.

The P19FA code refers to a fault in the HybridEV Electronics Coolant Pump Feedback Circuit.

This circuit controls and monitors the coolant pump that circulates coolant through various components. The Enable circuit controls the startergenerator coolant pump relay, which sends voltage to the coolant pump. The Feedback circuit provides pump speed information to the control module, but if there is an internal fault, it sends this information instead.

The HybridEV Powertrain Control Module 1 detects the fault and sets the Diagnostic Trouble Code (DTC) if the Coolant Pump Feedback circuit frequency is greater than 355 Hz.

What are the possible causes of the P19FA automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P19FA 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 related wiring harness and connectors to fix the P19FA fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P19FA fault code, you can fix it by visually inspecting the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Also, check the “Possible Causes” listed above to ensure that the issue is not caused by a faulty Starter/Generator Coolant Pump Relay, faulty Starter/Generator Coolant Pump, Starter/Generator Coolant Pump harness that is open or shorted, Starter/Generator Coolant Pump circuit poor electrical connection, or a faulty Starter/Generator Control Module.

What are the symptoms of the P19FA automobile fault code?

The P19FA fault code is indicated by the Engine Light ON or Service Engine Soon Warning Light. The possible causes of this fault code include a faulty Starter/Generator Coolant Pump Relay, faulty Starter/Generator Coolant Pump, open or shorted Starter/Generator Coolant Pump harness, poor electrical connection in the Starter/Generator Coolant Pump circuit, or a faulty Starter/Generator Control Module. To fix this issue, one 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.
