Details of the Audi p2185 OBD Code
Audi fault code P2185 relates to a cooling system performance issue.
Audi OBD code P2185 means the Engine Coolant Temperature Sensor 2 Circuit High input.
This code is triggered by the Engine Control Module (ECM) when it detects a high voltage signal from the Engine Coolant Temperature Sensor 2. This sensor is usually located near the thermostat housing or on the radiator.
It monitors the temperature of the engine coolant and sends this information to the ECM for proper engine operation and fuel delivery.
If the ECM receives a high voltage signal from this sensor, it will trigger the P2185 fault code.
Mechanic’s Tech Notes
P2185 is a fault code related to the coolant temperature sensor circuit on Audi vehicles.
To diagnose and fix OBDII code P2185 on an Audi, start by checking the coolant temperature sensor (CTS) for proper operation.
Use a multimeter to test the sensor’s resistance and compare it to specifications.
Inspect the CTS wiring for any damage or corrosion.
Next, verify the cooling system is functioning correctly by checking coolant levels and ensuring the thermostat is working.
If no issues are found, consider checking the engine control module (ECM) for any faults related to coolant temperature readings.
Resetting the code and monitoring for its return after these checks can help pinpoint the root cause.
FAQ
Common causes of OBD code P2185 in an Audi: Low coolant level, faulty ECT sensor, stuck thermostat, open/shorted sensor harness, poor electrical connection. Inspect and repair as needed.
Diagnose and fix OBD code P2185 in your Audi by checking for low coolant level, faulty ECT sensor, stuck thermostat, or wiring issues. Inspect wiring harness and connectors for damage.
