Wrench light

This morning on my 15 min drive to work my wrench light came on. i don't get over 30mph the whole time. I tired to get the code before i shut the truck off with my sct livewire but it showed no codes with the light on. It didn't drive any different no loss of power. When i checked memory codes with our shops modis scanner nothing unusual came up besides the fuel circuit fault, which i know about the gauge cluster needs repaired every now and then i cant listen to the radio or roll down the windows. All my numbers on my livewire looked normal. This is the first time it's come on since ive had the over boost issue fixed. So i am at a loss here on what it could be.

Kinda of a kick in the pants after i just saved myself a few hundred on wheel bearings and ball joints. Had a grinding noise at different speeds. Couldn't find anything lose on the front end but still had a grinding noise. Ended up being the exhaust shifted and was rubbing up against the frame.


Thanks

Tranny temps also come into play with the wrench light. You need to look at live data while this is happening. A data log would be good also.

Already done changed it. Still not exactly sure on what i should be monitoring. I have EOT,ECT trans temp, All three FICM options, Battery volts, ICP pressure ICP duty cycle Now VGT duty cycle, boost, Speed(just cause my gauge is off). Only thing i know i need to do is get a separate gauge for oil pressure,egt's, and fuel pressure. but that's on hold till i have the funds for a 3in1 gauge.

It varies from truck to truck, and remember that it's a DESIRED value, not an actual position of the VGT solenoid.

Although your ECT and EOT are a bit low, all those values look pretty normal to me.

I gotta install my new tstat to fix those temps. Still deciding of I wanna put the 200* in or a stock one. On a hot day it'll get to normal temps. The temp was 68 last night

At that temp it's fueling it heavy to get the temp above 185, replace the t-stat.
