fault code P2425

Post by KennyW »

Hi All,

When clearing some faults the above appeared as a permanent fault

P2425

Control of the bypass of the EGR exchanger

Open circuit.

Could this be the control solenoid valve ?

P2425 on this engine ECU is the control of the EGR Exchanger Bypass being 'open circuit' for 2 seconds Kenny.

It may disappear after 5 minutes but only when the engine is hot. The fault will cause the deactivation of the initialisation of the EGR valve.

Possible causes: Electrical harness, Connectors, EGR exchanger bypass control solenoid valve, EGR exchanger bypass, Fuse.
