P2141

DTC P2141, sometimes indicated as P214100 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 exhaust gas recirculation throttle control circuit "a" low.

The exhaust gas recirculation (EGR) system routes exhaust gases back into the engine to reduce emissions. The EGR throttle control circuit "A" low fault code means the EGR throttle control is not opening fully, which reduces the effectiveness of the EGR system and can increase emissions.
There are several possible causes for this fault code, including a defective EGR valve, a dirty or clogged EGR valve, a defective EGR throttle position sensor, or a defective engine computer.
The best way to diagnose and fix this fault code is to start by checking the EGR valve and EGR valve position sensor. If either of these components are defective, they will need to be replaced. If the problem is not with the EGR valve or position sensor, then the engine computer may need to be replaced.
