Thermostat Heater Control Circuit

The control circuit is most likely either open or short.

Thermostat heater control circuit.

The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver. The thermostat heater unit requires inputs from a variety of temperature sensors and engine sensors in order to adjust engine coolant flow and achieve optimal engine temperature. The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat. The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver.

The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver. What does code p0597 mean. Thermostat heater control circuit high. If a pcm powertrain control module stores this code it s because the engine s thermostat is experiencing an issue with the control voltage.

The function of the thermostat is to control the flow of the coolant or temperature of the engine electronically part throttle improves fuel economy and reduces emissions. An electronically controlled thermostat is composed of multiple temperature and load sensors a computer program and a control housing with a built in thermostat. This entire system of sensors and electric components is called the thermostat heater control circuit. This is a generic powertrain diagnostic trouble code dtc which means it covers all makes models 1996 newer.

The driver is equipped with a feedback circuit that is pulled up to a voltage. The driver is equipped with a feedback circuit that is pulled up to. The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver. The driver is equipped with a feedback circuit that is pulled up to.

The p0597 trouble code signifies that a thermostat heater control circuit is open. What does that mean. The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat. The engine coolant thermostat heater controls coolant flow and regulates the engine operating temperature.

The driver is equipped with a feedback circuit that is pulled up to a voltage. The ecm supplies 12 v to the thermostat. However specific troubleshooting steps will vary depending on the vehicle. What the p0597 code means.

The ecm supplies 12 v to the thermostat. We recommend torque pro. The engine coolant thermostat heater controls coolant flow and regulates the engine operating temperature. Thermostat heater control circuit open.

Obd ii fault code p0597 is a generic code that is defined as thermostat heater control system circuit open and is set when the pcm powertrain control module detects an open circuit loss of continuity in the heater control circuit of an electrically assisted thermostat also known as a mapped thermostat.
