P261C Code - Coolant Pump 'B' Control Circuit Low
Quick Answer
The Engine Control Module (ECM) controls the engine water pump assembly by calculating the necessary amount of coolant flow based on engine coolant temperature, engine speed, and vehicle speed information. Common causes include Faulty Engine Water Pump Assembly, Engine Water Pump Assembly harness is open or shorted, Engine Water Pump Assembly poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
