The automobile fault code P19FB 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. Therefore, the total cost of fixing this fault code can range from $75 to $150.

These factors are important to consider when diagnosing and fixing the P19FB fault code in an automobile.

The P19FB 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 Enable circuit controls the startergenerator coolant pump relay.

The Feedback circuit provides pump speed information to the control module. If the pump detects an internal fault, it sends this information on the same feedback circuit instead of pump speed information.

The DTC will be set if the Coolant Pump Feedback circuit frequency is less than 20 Hz.

What are the possible causes of the P19FB automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P19FB 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 the Starter/Generator Coolant Pump Relay be checked for faults?

If the engine light is on, it could be due to a faulty Starter/Generator Coolant Pump Relay. To check for faults, inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, or pushed out connector pins. Check the Starter/Generator Coolant Pump and its circuit for any electrical connection issues. Also, verify the Starter/Generator Control Module for any faults.

What steps should be taken to visually inspect the wiring harness and connectors related to the P19FB fault code?

To visually inspect the wiring harness and connectors related to the P19FB fault code, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Check the “Possible Causes” listed above and visually inspect the related wiring harness and connectors.
