P2601

DTC P2601, sometimes indicated as P260100 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing coolant pump "a" control circuit range/performance.

The P2601 code means that the engine control module (ECM) has detected a problem with the coolant pump "A" control circuit range/performance. This could mean that there is a problem with the coolant pump itself, or with the wiring or connectors that connect the pump to the ECM.
If you have this code, check the wiring and connectors between the coolant pump and the ECM, and make sure they are properly connected and in good condition. If the wiring or connectors are OK, then replace the coolant pump.
