Wrench symbol on dash
I was on way to the airport yesterday and th yellow wrench light came up on the dash, didnt notice any loss of power or anything else wrong. turned of the engine and it went away for a while and then back on. Thismorning it didnt start like it should, any ideas please........Ive not had the truck back that long after the dealers screwed me over my warrenty... Thanks for your time.

I think the engine symbol is more closely related to a check engine light. Whereas the wrench symbol indicates problems with the electronic throttle control. In either case you should check the codes to determine the problem.

could be that it is the EOT/ECT out of range if you have the recent flash. Had that show on mine and thats what it ended up being. And I confirmed with a code read and also running it and watching the point where it came on while observing the two temps get past the 15 degree limit. Now Im setting myself up to replace the coolers.

Ok thanks, i have the lateset flash, and havent had it come on again so will just have to wait to see what happens. It is still hard to start in the morning though. I will have to go get a new code reader cant seem to find mine. Thanks again for the info guys...

What were you doing??????
Here is what I have seen. High humidity and outside temps in the 80's, full egr delete and tunes from Elite or SCT. Cruising at a steady speed of 70 for about 25 miles and A/C on high. Wrench light comes on, 22 degree spread of eot/ect. AC off it doesnt seem to come on. Towing it comes on within 20 miles unless I turn A/C off. Put egr valve back in and NOW the engine cooling fan comes on and the wrench light seems to stay off. fyi

You have just hit the nail on the head !!!! I was cruising down the highway on a hot day with ac on. The only thing i have had the EGR valve disconected for the last 3/4 months. I have pluged it back in now. I have instaled an Edge Juice with Attitude which i leave on #1 Mileage. I havnt had the light come back on yet but also i havnt been down the highway. But now its not wanting to start very well it fires but wont start straight away. I have just changed the oil and for the first time put a wicks filter the one with the lid on the filter, Im hoping its that. I am going to get a MC one and put it in. Fingures crossed.Thanks Ben

If I have time Im going to do somemore looking as to the effect when there is a no flow code.
