P2145 Fault Code
P2145 OBD-II Trouble Code Short Description
Exhaust Gas Recirculation Vent Control Circuit High
What does trouble code P2145 mean?
The P2145 fault code indicates an issue with the Exhaust Gas Recirculation (EGR) vent control circuit being too high. This code is often associated with the vehicle's emissions control system, which is designed to reduce harmful pollutants by recirculating a portion of the exhaust back into the engine to be burned again. When the EGR vent control circuit reports a high voltage or signal, it suggests a problem in the EGR system that may affect performance and emissions.
