97 psd lots of codes
 

Ok guys sorking on my buddies other truck and it started to idle at 900 and lots of injector noise, put the truck in drive anx returns to normal. The truck threw 5 codes. P1280 p0472 p0198 p0603 p1211. Has anyone had these problems before, any help greatly apreciated. Still havent got his other truck running either, and he's running out of trucks for work.

Nothing really sticks out that can't be explained... the 1280 and 1211 are ICP related... the 0603 is typically from batt's being disconnected... the 0198 is EOT related... and the 0472 is exhaust back pressure sensor related...

Not really sure about the idle... Does your scanner that you guys are using have the ability to see the ICP pressure and Duty Cycle % at idle... might help figure this out...

No, his programer is a cheap one, it only shows fuel presure. Does the icp need to be cleaned reguarly, his truck has 208xxx on it. Be just bought it, had the trans rebuilt, and the oil changed. He used rotella, which i have never had a problem with. Iz tbeir a 200k tune up for these trucks, ssdms like tbey all get problems around there.

How does it show fuel pressure? The fuel pressure doesn't have a sensor so I'm not sure where that number is coming from...

ICP doesn't need to be cleaned, but there shouldn't be any oil in the connector.

Not sure on the conector, i didnt unplug it. Do you think its reading the low oil pressure?

The computer saw a value that it didn't like and that's what the code is saying. Usually means it wasn't supplying the oil pressure that was being required. Doesn't matter. Neither here nor there... I can get that code if I really tried hard enough.

Need to find out why it's idling so high.

It threw all of those codes after it started with the high idle, it only does it in park or neutral, if you put it in drive it idles just fine. He had the trans built about a month ago, would it have something to do with it?
