Can I replace Calif. EGR value with a FED EGV without any problems? My 93' RX7 was built for CA emissions, but resides in Oregon. Mazda Comp only has FED EGR in stock and their about $60 cheaper.

 

No. without the position sensor on the egr valve that will plug into wiring harness on the car the Cali emissions ecu will throw a check engine light. as far as driveability problems associated with it i dont know.
have you pulled it to make sure that the valve is not stuk open or closed? also that the vac line is in good order?
there is a way to wire a relay into the system to bypass it do a search for it was not to long ago it was floating around

better question is if the M2 ecu in your car is cali or fed...

 

get a federal ecu and swap out the cali ecu . this will take care of the check engine lite problem. I bet the egr valve is working ok. its that cali electronic sensor giving you the problem.

 

I have not pulled the egr yet. The check engine light came on just has I was pulling into clean air station to have my emissions checked. My CO2 was too high and I didn't pass. When home and pulled the code and it said the egr was bad. My vac line should be good they all have been replaced and plastic wire tied. If I have remove the throttle body I'm going the replace the egr anyways and any other solenoid that has not been replaced yet.
When I drove the car yesterday the check light was off and stayed off for the fifteen mile ride.
I don't know if M2 reprogrammed my ecu has cailf or fed. I never thought about it until now. Does anyone know how they reprogrammed them...if they had a calif and fed program?

 

I'm confused now. mad7tist is saying NO and jeff p is saying swap it out with a fed. Not sure which way to go here guys.

 

Only if it's not the 94 federal model....seems to be the same as a cali. ecu as it has an elctrical connection to look at the egr. 93 or 95 federal ecu is what you want,if you want to avoid throwing an egr code.

 

I'm not going to replace the ecu. I'll get a calif egr and sensor if needed.

 

I have a cal egr valve that you can have.

PM me your address & I will ship it to you.

IM in WA so it should only take a day or two to get to you.
