Code P142A GMC Description
The P142A GMC code indicates a problem with the EGR (Exhaust Gas Recirculation) temperature sensor 2 intake air temperature 2 not being plausible. This means that the temperature readings from the sensor are not aligning with what is expected, which can lead to issues with the vehicle's emissions and overall performance. The EGR system is responsible for recirculating a portion of the exhaust gases back into the engine cylinders to reduce emissions of nitrogen oxides (NOx). The temperature sensor helps monitor the temperature of the exhaust gases and intake air to ensure optimal performance and emissions control.
Common Causes of P142A GMC
- Faulty EGR temperature sensor
- Wiring issues
- Malfunctioning EGR valve
- Problem with the intake air temperature sensor
Symptoms of P142A GMC
