This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car has detected that the control module for one of the coolant pumps is getting too hot.
The P26F9 code indicates that the control module responsible for operating Coolant Pump C has exceeded its normal temperature range.
The control module for Coolant Pump C monitors the temperature of the module itself. If the temperature exceeds a predefined threshold, the module sends a signal to the vehicle's main computer, triggering the P26F9 code. This could be due to excessive current draw, poor ventilation, or a malfunction within the module.
• Check Engine Light illuminated
• Overheating engine
• Reduced engine performance
• Faulty Coolant Pump C control module
• Electrical short or excessive current draw
• Poor ventilation or cooling of the module
Coolant: A fluid used to keep the engine from overheating.
Control Module: An electronic component that manages specific functions in a vehicle.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to Coolant Pump C.
• Check for any signs of overheating or damage to the control module.
• Replace the faulty Coolant Pump C control module.
• Repair or replace damaged wiring or connectors.
• Ensure proper ventilation and cooling for the module.

This code has been associated with vehicles experiencing cooling system issues, particularly in models with complex cooling systems.
High – This code can lead to engine overheating, which can cause severe engine damage if not addressed promptly.
Driving with an overheating engine can cause significant damage and may lead to unsafe driving conditions.
• Engine at operating temperature
• Vehicle in a safe, stationary position
Coolant Pump C control module is typically located near the engine bay, often close to the coolant pump itself.
Q: Can I drive my car with a P26F9 code?
A: It's not recommended to drive with this code active, as it can lead to engine overheating.
Q: What happens if I ignore the P26F9 code?
A: Ignoring this code can result in engine overheating and potentially severe engine damage.
