Code P26A7 Dodge Description
The Coolant Three Way Valve is supplied Battery voltage and a ground circuit. The Coolant Three Way Valve position is electrically controlled using a 12 volt PWM high side signal from the Powertrain Control Module (PCM). The PCM will send a PWM signal of 25% or 75% to the Coolant Three Way Valve, depending on whether the coolant is desired to be directed to the Heater Core or the TMU. The Coolant Three Way Valve has an internal position sensor that sends a signal back to the PCM. The sensor operates as a typical three wire sensor which has a 5-Volt Supply circuit, Signal circuit, and Return circuit.

- Faulty Coolant Three Way Valve Sensor
- Coolant Three Way Valve Sensor harness is open or shorted
- Coolant Three Way Valve Sensor circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
