What is the EGP fault in the engine?

[VonRiver]

Engine EGP refers to a fault in one or both of the two temperature sensors, involving either the circuit or the internal components of the sensor itself. This fault may be caused by a short circuit, an open circuit, or a malfunction in the temperature sensor. Solution reference: Replace both sensors. Exhaust processor: The exhaust processor is equipped with two catalytic converter temperature sensors and one NOX sensor. The two temperature sensors are located at the inlet and outlet of the catalytic converter, respectively referred to as the inlet and outlet temperature sensors. Main function: The main function is to detect the temperature of the exhaust gases emitted by the engine. When the detected exhaust temperature exceeds 200°C, the engine's electronic control unit receives this signal and sends corresponding execution signals to the metering injection pump to control the injection of a certain amount of urea solution into the exhaust pipe. The urea solution decomposes into NH3 when heated, and NH3 reacts with NOX in the exhaust gases to produce non-polluting N2 and H2O.
