So I went down to the lumber yard today to get some strock for my latest project and the Check Engine Light comes on.
I immediately think it's the P0401 low EGR flow and can't wait for Sumotoy's response that my fan clutch is timed to low and excessively cooling the engine giving a false negative on the EGR system.
Well I get home and scanned the truck to find that I have a Sensor 1, Bank 1 O2 problem. Great, I ordered both of the sensors 2 years ago but stalled on the front one because the nuts were rusted pretty damn bad and I didn't feel like fighting with it when it was working just fine.
I decided to go out and survey the situation and half an hour I was done. The nuts practically fell off and all I had to do is run a die down the stud and bolt the new sensor in.
Attached is a pic of what I was able to find after removing the nuts.
