Hi there. The P0597 OBD-II trouble code is for the thermostat heater control circuit. This means that the thermostat is electronically controlled in your vehicle. Some of the common causes of this code include a loose or corroded connector on the thermostat, coolant leak in the cooling system - make sure that all connections are tight, the thermostat could have failed - stuck open or partially open or there could be a short in the wiring harness between the computer and thermostat. If you’d like us to replace your thermostat, please fill out this request for a thermostat replacement and we can send you a quote.
