    I have a 2013 Persona Prius. Had the check engine light come on with DTC P261C Engine Coolant Pump 'B' Control Circuit Low. Had the Engine coolant pump checked and it works perfectly. Figured out that the connector has no power coming through it (car powered on). The car starts fine and can drive. My question is does anyone know how to go about fixing the connector or would I need a completely new wire harness? Is there anything I'm missing or can check? Any advise would be greatly appreciated. Thanks

    Unless you spotted an obvious problem with the connector itself causing it not to pass voltage, the problem may be anywhere upstream in the circuit. I'd just go ahead and follow the troubleshooting steps in the repair manual for P261C, they're usually organized to check the most-likely/easiest things first, so you get to a solution soonest.

    The wiring diagram will also help you locate all the players involved in the game.
