P2144 Fault Code
P2144 OBD-II Trouble Code Short Description
Exhaust Gas Recirculation Vent Control Circuit Low
What does trouble code P2144 mean?
The P2144 fault code indicates a low voltage signal from the Exhaust Gas Recirculation (EGR) vent control circuit. This circuit is crucial for regulating the flow of exhaust gases back into the engine to reduce emissions and improve fuel efficiency. When the voltage falls below the expected range, it triggers this error code.

- Poor electrical connection or corroded terminals
- Malfunctioning engine control module (ECM)
- Contaminated EGR passages leading to restricted flow
Possible Solutions
How to fix P2144?
- Inspect and repair or replace damaged wiring and connectors
