Default EGR CEL

My friend has an h22 in a 95 accord with a skunk2 IM. There is no hole to put the egr valve and he is getting a cel. Is there anyway around this?

im not a pro but i would assume that you could take that pin out of the ecu or jump the wire out in some way

another option can be to tap a hole in the IM to put the EGR.

I am afraid that it is much more complicated than that my friend but I do not have a work around for you for the computer. The E.G.R. system is made up of many components and they all give feedback to the computer and the computer looks for these feedback signals, too many to work around the easy way. Dont drill the hole either in my opinion.

I cant think of anything in the egr system that sends a signal to the ecu besides the egr lift sensor. What if he plugged an egr valve onto the electrical connector and just left it hanging off to the side? Wouldn't that trick the ecu into thinking there's a working egr valve? (as long as the rest of the system was working properly)

What controls the vacuum to lift the E.G.R., and what controls that solenoid and does the E.C.U. check that too and some other components, maybe not as many as I made it sound though sorry. When actual E.G.R. gasses are burned does the E.C.M. expect to see any activity on the O2 sensor???

You are correct though, there is no backpressure sensor, no temperature sensor but the computer should at least do a circuit test on the few other devices in a normal system, hence several O.B.D. codes for E.G.R.

OK, run really long vacuum hoses and put everything in the trunk, kewl.

On the obd0 and obd1 models, the ecu energizes the vacuum control solenoid And watches the egr lift sensor to detect a problem with the system. Code 12 is the only egr error code they have. Up through 1995 the ecu doesn't check flow. (the 95 v6 model may monitor egr flow, i'm not sure on it)

On obd2 models, (96 and newer and maybe the 95 v6) the ecu monitors the signal from the map sensor to determine egr flow.
