This has been a long time in coming. I have a '91 240, 50-state legal model. It has an EGR system, but I don't know a thing about the system. Not to seem ignorant, but I have a few questions.
Things like, where is the EGR valve?
What is that little deal on the strut tower beneath the ABS modulator?
What exactly does it do?
Does it make noise? This is an honest question because I've been tracing a ticking noise for 50k, to no avail.
I only get a fault code from EGR when I disturb vacuum lines with the engine running, so this is more of a "what is the deal with this system" question, more than "something's wrong with this system". Besides, the fault code for EGR says only "EGR system faulty". No real specifics.
Any insight into the EGR system would be appreciated, since I'm in the dark about that part.
