My CEL is on and the computer reads an issue with the exhaust pressure control valve. I was quoted $628 for parts and labor to fix. Is that a legitimate price? Seems steep for a valve. If I do not replace it right away will anything negative happen other than my cat converter will not heat up as fast?

Thanks for the anticipate advice!

that valve is for EGR system function, located on and try spraying the spring w/lube, may be rusted up. IMHO, poor design to have a spring where it can get corroded.
Hey man the link wont come up. What exactly was that article saying? I'm having the same problem right now. I have a PO48E code.
