DTC's

I checked the truck today for trouble codes, no service engine light but I just thought i would check.

DTC p0475- exhaust pressure control valve error
DTC p0603- internal control mod KAM error
DTC p0541- manifold intake air heater circuit LOW

I think I know about the exhaust pressure control valve, mines disconected.
Also the manifold intake heater on my truck is caped with a plug..
The internal control mod Kam error is a new one for me, any help on this one would be great.

P>S the truck runs fine but if its down on power I would like to know.

anytime we pull codes at work, we record them, erase them, then take the victim (er, I mean CUSTOMER's) car through a drive cycle...

then we scan it again.. the codes that come back are the ones we wroory about..

so record them, and clear them, and check it again in a few days...

The KAM code means your battery was disconnected some time in the past.

or you cleared the codes...

 

[DaveBen]

No, clearing the codes will not set the KAM code. It is set when the power is disconnected from the PCM.
