CEL P0600 code

[Roscopcoletrain]

All was well, on way home, CEL came on. Tossed the scan tool on, P0600 code. Tried clearing, came right back. Truck ran fine, no obvious issues I could tell.

 

Suggestions?

 I will say........Bad ground(s). Check your neg cable at battery (remove & clean) & where it mounts on the other end. Next, check & clean ground on drivers side upper dash. Watch this video. There's a TSB on this since it was an issue with some earlier trucks.  Keep us (me) posted

 

2014 Chevy Silverado electrical issues and Stabilitrack issue FIXED!!!!

So cleaned the battery, checked grounds, all seem ok. CEL was gone once I hooked everything up again, but it came back after 5min of driving. I looked at the ground under the dash, don't see an issue with it like in the video posted. 

 

Sooooo dropping off at dealer on Friday

Waiting for confirmation, but seems like oil pump related.

Could be a bad battery.I don't see how the oil pump would throw that code.

This is why a GOOD code reader is important.  Something like this can read GM codes quite well:  BlueDriver Scan Tool | BlueDriver

P0600 isn't a code at all in the service manual.  P06DD is however.  If the dealer is telling you its oil pump related, they found P06DD in there and not a P0600.  

 

P06DD is Engine Oil Pressure Control Solenoid Valve Performance.  Truck will most likely end up needing a new oil pump.

yeah you nailed it. Will need a new pump. Feel like Im driving a ticking time bomb lol. 

 

Edit... Is there harm driving while I wait for parts and such to come in? My oil pressure based on the garage seems normal to me.

 

Odd after I got the truck back, CEL is out, drove the hour home and still haven't come on. 

 

I've got a camping trip coming up next weekend, doubtful the parts will be in before that, but I'm also worried about pulling a trailer and the pump fails. Will the pump just fail? @newdude
