Exhaust Gas Recirculation Cooling Valve Control Circuit Open
P2425 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation cooling bypass valve (EGRCBV) control circuit is open.
The ECM has detected an open circuit for controlling the cooling bypass valve for the EGR system and sets the P2425 code and turns on the Check Engine Light.
The EGRCBV has an open circuit in the valve.
The connection to the EGRCBV has loose or corroded pins in the connection.
Scans codes and documents the freeze frame data in order to verify the problem
Clears the engine and ETC codes and road tests the vehicle to verify the concern comes back
Visually checks the vacuum hoses, wiring, and connections to the EGR valve and control solenoid
Disconnects and checks that the EGRCBV is getting the proper power and ground signals from the ECM to open the valve when the ECM is commanded to open, and close the valve through the scanner.
A failed EGR valve can cause the engine to have excessive ignition pre-ignition that can cause internal engine damage to the piston and valves.
The Check Engine Light on will cause the vehicle to fail emission testing from excessive NOX gases.
Code P2425 is for the EGR cooler coolant flow control valve, and if the EGR is not cooled correctly, it can get carbon fouled too quick and become clogged. This can increase the pre-ignition in the engine and cause internal piston and cylinder head damage.
