Thermostat Heater Control Circuit

What the p0597 code means.

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 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 that mean.

This is a generic powertrain diagnostic trouble code dtc which means it covers all makes models 1996 newer. What does that mean. Thermostat heater control circuit open. The driver is equipped with a feedback circuit that is pulled up to a voltage.

An electronically controlled thermostat is composed of multiple temperature and load sensors a computer program and a control housing with a built in thermostat. The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver. However specific troubleshooting steps will vary depending on the vehicle. 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.

The ecm supplies 12 v to the thermostat. The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat. The driver is equipped with a feedback circuit that is pulled up to a voltage. However specific troubleshooting steps will vary depending on the vehicle.

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 engine coolant thermostat heater controls coolant flow and regulates the engine operating temperature. We recommend torque pro. The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat.

What does code p0597 mean. 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. The driver is equipped with a feedback circuit that is pulled up to.

If a pcm powertrain control module stores this code it s because the engine s thermostat is experiencing an issue with the control voltage. Thermostat heater control circuit high. 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. The p0597 trouble code signifies that a thermostat heater control circuit is open.

The ecm supplies 12 v to the thermostat.
