Code P0C26 Description
The P0C26 diagnostic trouble code (DTC) refers to the Auxiliary Transmission Fluid Pump Motor Current. This code typically indicates an issue with the electrical current being drawn by the auxiliary transmission fluid pump motor in the vehicle. The auxiliary transmission fluid pump is responsible for maintaining proper fluid circulation in the transmission system, which is essential for cooling and lubricating the transmission components.
Common Causes of P0C26
- Faulty auxiliary transmission fluid pump motor.
- Damaged or corroded wiring connections.
- Blown fuse related to the auxiliary transmission fluid pump motor.
- Issues with the transmission control module.
- Low transmission fluid levels or contaminated fluid.
Symptoms of P0C26
- Illumination of the check engine light on the dashboard.
- Transmission slipping or jerking during gear shifts.
- Decreased fuel efficiency.
- Transmission overheating.
- Unusual noises coming from the transmission system.
How to Fix P0C26
- Begin by using a diagnostic scan tool to confirm the P0C26 code and identify the specific issue with the auxiliary transmission fluid pump motor current.
- Inspect the wiring connections and connectors for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Check the fuse related to the auxiliary transmission fluid pump motor and replace if blown.
- Test the auxiliary transmission fluid pump motor for proper function and replace if found to be faulty.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0C26
The cost of repairing the auxiliary transmission fluid pump motor current issue can vary depending on the underlying cause and the specific components that need to be replaced. In general, the cost of parts for this repair can range from $100 to $500, while labor costs can add an additional $100 to $300. Overall, the total repair cost is likely to fall between $200 and $800.
