ok I cleaned out the epb sensor tube like you said to and you were right really dirty I cleaned it out. But I could not get the sensor off,I drove it today MUCH better alot more power and only smoked a little but still some smoke. When I was done with the job I sprayed some of that engin degreaser all over the enging just to clean it up and now all I do is smell diesel really bad in the truck when im driving so bad I need the windows open I hope its nothing I did and just that degreaser?? Also im getting a new code its P0528 fan speed sensor - no signal now what !

Hmmmm....

Might just have residual water or some cleaner still on the motor. I use purple power to clean my engine bay, amazing how well it works. Just dont let it sit on anything for a while. It needs to be rinsed off after about 5-10 minutes.

Sounds like the EPB helped. Too bad you couldn't get right to the sensor, I bet it would help more. I like to remove the sensor, clean that as good as possible, and then run pipe cleaners through the tube to ensure it's really clean. I can't help but wonder if that would almost cure your issues.

Being your tube was clogged, it probably wouldn't hurt to still clean the turbo. Just make sure you've got a day to do it. Leave yourself time. Not very difficult, but not something you want to rush either.

I will look into the fan speed sensor, but I wonder if it's just got water/chemical residue on it. Especially since it came on after you degreased the engine.

ok thanks for all you help. I will try to get out that sensor tomorrow.
