Thread: CEL Help

Have a few codes on a 1998 Se-r I've been trying to resolve. Here are the four codes.

Po400
Po325
P1105
Po171

Disregard the knock sensor code. The car has no egr on it, which is why I think Im getting the po400, po1105 and po171 codes. Is there any way around getting the cel's off with the egr completely removed?

Yep,it requires a resistor soldered between the old wires on the EGR plug.It's somewhere in the manifesto I would think.Do a little searching about EGR removal,and it will give you the resistance value you need.I did it to mine last year,and no more cel.
