Decode P1402: Unveiling The Symptoms And Solutions
When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the fault code P1402. This code indicates a problem with the Exhaust Gas Recirculation (EGR) Valve Position Sensor.
The EGR valve is responsible for recirculating a portion of the exhaust gases back into the engine to reduce emissions. However, if the EGR valve position sensor is malfunctioning, it can lead to issues with the engine’s performance and emissions control system.
It is important to address this fault code promptly to ensure optimal engine performance and to comply with emission regulations.
