Help! Turbo?

[61cadman]

I need some help, this is my first diesel. Earlier today my truck seemed Like it had a loss of power. Then on my way home from work when I started it my check engine light went on. My boost was registering very low if at all. Did my turbo go out? The motor has 87,000 miles and is stock. Looks like I may need some parts from Bulletproof. What would I need? A new turbo? Should I get an aftermarket turbo? Is an EGR delete good? Should I get a programmer, or tuner? How do they work? The truck seems to run fine just doesn't have the power it usually has. Thanks for any info.

Your waste gate probably stuck open. It may need cleaning and lubrication.

I agree with last post, however if it is something else before you go spending a lot of hard spent money, get it hooked up to a computer to check out that check engine light. That should get you a pretty good idea of what's wrong. Also if you are going to bulletproof your diesel I would strongly recommend sinister diesel- or mkmcustoms.com ( same company) they make and sell great quality parts and are usually pretty fair priced compared to other websites. Also if you call the number on their webpage you make custom package deals specific to your upgrade/performance needs. In opinion as far getting a tuner/programmer goes you may be able to get it to bypass the problem if it is a sensor but in long run it is still a problem and it may cause more problems even if your trucks computer is programmed to ignore it. Like I said your best bet is get your truck plugged in and find out about the C.E.L. And then take it from there.

Well, ends up the turbo started to work like normal again. The light was still on. I had it looked at and the code ended up being an exhaust backpressure sensor. They turned off the light and it has not been back on. I did order a new sensor, have not installed yet. Could this give me bad milage? Im running 35's is 10mpg sound about right?
Thanks

What year and size motor is it? And are we talking city or highway

[roche837]

you can pull and clean the old sensor, probably full of gunk, should be a good spare seeing how you got a new one

It's a 2005 6.0 diesel. Yeah I will try to clean it. How would I clean it?

When you remove it it will be plugged along with the tube going into the exhaust manifold i use some mechanics wire on the tube and a pick and carb chock cleaner on the sensor, come to find out this sensor on my 03 is not as critical as later years in that mine uses the signal from MASS air instead of ebp

Thank you , I will try and use as a back up.

For city mpg that's about right but hwy should be higher. I have 33's and I get 18-20 hwy in my 03' 6.0L excursion, I wouldn't think two inches difference in tire height would take away almost ten mpg. As far as the sensor giving you bad mileage it is definitely a possibility , not enough exhaust back pressure could mean you have an exhaust leak before the turbo which means your losing valuable horse power ( just an example) or if you have too much it could mean you're recirculating more exhaust than the motor can burn I.e. Black smoke out of the tailpipe which is essentially unburned fuel. I hope this makes sense
