Code P1F58 Description

The valve provides position feedback to the hybrid/EV powertrain control module 2 based on a potentiometer in the valve. The hybrid/EV powertrain control module 2 uses this feedback to monitor the valve position. Different valve positions correspond to different resistance values. The hybrid/EV powertrain control module 2 determines the resistance values corresponding to the end stop positions of the valve by moving the valve to an end-stop and back to its original position when the vehicle is first turned on. This is referred to as the hybrid/EV powertrain control module 2 "diagnostic learn" the valve. This provides a valve shaft breakage test and allows the hybrid/EV powertrain control module 2 to "learn" the position feedback value that corresponds to that end-stop. The end-stop that is used at each Vehicle in Service Mode alternates between each end, the radiator end one time, the chiller end the next time, the radiator end the next time, etc.

Frequently Asked Questions about P1F58 Code

1. What does the OBDII code P1F58 mean?

The P1F58 code indicates that the Hybrid/EV Battery Pack Coolant Control Valve Position Sensor has detected an unexpected position change, signaling a performance issue.

2. What are the common symptoms of the P1F58 code?

Symptoms may include an illuminated check engine light, reduced hybrid or EV performance, overheating of the battery pack, or abnormal coolant system operation.

3. What causes the P1F58 code to be triggered?

Potential causes include a faulty coolant control valve, position sensor failure, wiring or connector issues, or coolant contamination affecting valve operation.

4. Can I continue driving with the P1F58 code?

Itâ€™s not recommended to drive for extended periods, as battery pack overheating or reduced performance may worsen the issue and cause further damage.

5. How is the P1F58 code diagnosed?

A technician will use a scan tool to verify the code, inspect the coolant control valve and position sensor, check wiring and connectors, and test the coolant flow system for obstructions or leaks.

6. How do you fix the P1F58 code?

Repairs may involve replacing the coolant control valve, repairing or replacing damaged wiring, cleaning or replacing the position sensor, or flushing and refilling the coolant system.

7. How much does it cost to fix the P1F58 code?

Repair costs can vary but typically range from $150 to $500, depending on whether the valve, sensor, or wiring needs replacement.

8. Can low coolant levels cause the P1F58 code?

Yes, low coolant levels can affect the operation of the coolant control valve and trigger the P1F58 code, so checking and refilling the coolant is a good first step.

9. Could a software issue cause the P1F58 code?

In some cases, a software glitch in the hybrid/EV control module might contribute to the issue, requiring a software update or reprogramming.

10. How can I prevent the P1F58 code from recurring?
