Where is the diagnostic trouble code p2185 located?
P2185 VOLKSWAGEN Description This Diagnostic Trouble Code (DTC) is stored in the engine control module when the output from the Engine Coolant Temperature (ECT) Sensor is not as expected or missing.
What causes a bad coolant sensor on a p2185 engine?
An open in the ground circuit between the #2 ECT sensor and the PCM A short in the voltage feed between the sensor and the PCM A bad temperature sensor (shorted internally) First, if you have access to a scan tool, check the reading of the #2 coolant sensor.
What is the function of the p2185 ECT sensor?
Nonetheless, if we take the most common definition of code P2185 to be “Coolant Temperature Sensor at Radiator Outlet Signal High”, the function of the affected sensor is to monitor the temperature of the engine coolant at the radiator outlet, from where the cooled coolant is passed back into the engine.
Where is the coolant temperature sensor 2 located?
Engine Coolant Temperature (ECT) sensor 2 is a thermistor attached to the radiator. The Powertrain Control Module (PCM) applies voltage (about 5 V) to the ECT2 signal circuit through a pull up resistor. As the engine coolant temperature cools, ECT sensor 2 resistance increases, and the PCM detects a high signal voltage.
What causes the p2185 engine coolant temperature code?
What causes the P2185 code? This ECT (Engine Coolant Temperature) is one of two sensors the PCM uses to monitor the operating temperature of the engine. The PCM compares the voltage readings of sensor 1, sensor 2, and how long the motor has been running.
