exhaust pressure control valve??
I had my nephew pull the codes on my truck today(99 7.3) the check engine soon light flickered several times pulling a mountain with a loaded trailer(about 4k pds.)
He's not a diesel mechanic so after I got the codes I'm on my own
exhaust pressure control valve performance
stuck or damaged linkage
exhaust pressure regulater valve(epr)
What/where is the exhaust pressure control valve(we think it's the waste gate) what/where is the EPRV we think that is the sensor the tube from the exhaust manifold runs up to behind the HPOP.
As a side note: a coworker has a 01 7.3 with a programmer on it, in the owners manual it says the check engine soon light may flash under heavy loads. I called Schip to see if they had a similar warning said they didn't. Anybody else had or heard of this?
