The P2601 code is a general OBD-II diagnostic trouble code (DTC) that indicates a fault with the coolant pump control circuit range/performance.
The coolant pump is an electronically controlled auxiliary pump used to support the coolant system with extra flow. This extra flow is used to keep the coolant circulating at low RPMs and also when the engine is off. When the ECM detects out-of-range voltage or poor performance, it sets the P2601 code. When the code is set, it triggers the Check Engine Light to be visible on the dashboard. The code will remain until normal operation is found or the fault is repaired.
The most likely causes of the P2601 code are:
The most common symptoms are:
A qualified technician will follow these steps in their entirety to diagnose the P2601 code:
Using a scan tool hooked up to the vehicle's DLC port, check for any codes stored in the ECM
Note all codes stored as well any freeze frame data that is present.
Clear all codes for a fresh slate
Perform a road test of the vehicle under similar circumstances to the freeze frame data
Check that P2601 is present
Perform a visual inspection to look for any signs of failed components or coolant leaks
Check for auxiliary pump operation
Test the coolant pump relay
Use a multimeter check for voltage present at the coolant pump
The most common mistake is made when voltage is not found at the coolant pump and the pump is replaced, when all along it was the relay that was at fault. Step-by-step diagnosis simplifies and greatly increases the accuracy of repairs.
P2601 can cause overheating, which can lead to serious damage to the engine. A vehicle that is overheating should not be driven until the fault is repaired.
