Hi all
I have a 06 Jimny m13a. I have been getting a P0401 fault (EGR insufficient Flow detected).
I tested the pins on the EGR its self and replaced due to low resistance between pins f & e as per the manual.

The motor is standard but it does have a set of extractors on, which i'm not sure but may be contributing to the low flow.
When the valve was out i started the car thinking i would hear the exhaust gas coming through the port or at least be able to feel it but i couldn't.
Does anyone know if at idle with the EGR removed i should be feeling the exhaust gas ?
its it likely that the port is blocked ? If it is blocked is is best to clear it via the EGR from the back of the motor or remove the exhaust manifold ?
Would the increased exhaust flow due to the extractors being installed be contributing to a low flow at the EGR ?
or am i missing something ?
The line from the inlet manifold to EGR is clean and plenty of vacuum at the EGR.

Any help would be appreciated.


Thanks

Yes. you should feel (and hear) the gasses through the EGR if the valve is removed.

Do the extractors have an EGR passage between the #4 port and the EGR? The passage may be blocked in the header or in the head, the best way to clear it will depend on where the blockage is

Thanks for the reply.

I pulled the extractors off and found that where the egr pipe tees into cylinder four pipe there was no hole.
Should get some air now!!

Thanks
