Engine Coolant Thermostat Heater Control Circuit High Voltage

The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat.

Engine coolant thermostat heater control circuit high voltage.

Thermostat heater control circuit open. If greater than the specified value test the control circuit for an open high resistance. Remove the electrical. Test for less than 5 ω between the control circuit terminal 43 x1 at the k20 engine control module harness connector and terminal 1 at the e41 engine coolant thermostat heater harness connector.

P0559 can also be set by a short to voltage condition. The p0599 code is stored when the pcm detects an abnormally high voltage reading from the thermostat heater unit. The engine coolant thermostat heater controls coolant flow and regulates the engine operating temperature. However specific troubleshooting steps will vary depending on the vehicle.

P0598 engine coolant thermostat heater control circuit low voltage. The driver is equipped with a feedback circuit that is pulled up to a voltage. The ecm can determine if the control circuit is open shorted to ground or shorted to a voltage by monitoring the feedback voltage. 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 codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat. What does that mean. 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.

This is a generic powertrain diagnostic trouble code dtc which means it covers all makes models 1996 newer.
