P2182

DTC P2182, sometimes indicated as P218200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing engine coolant temperature sensor 2 circuit.

This code may be set if the engine coolant temperature sensor 2 is not reading within specification. Sensor 2 is used by the engine control module (ECM) to calculate the engine coolant temperature. This code may also be set if the ECM detects a short to ground or open circuit in the sensor 2 circuit.
If this code is set, inspect the engine coolant temperature sensor 2 and the wiring harness for damage. If the sensor or wiring is found to be damaged, replace them as necessary. If the code persists, the ECM may need to be diagnosed and repaired.
