Check Engine Light On
 

hey guys new to the forum i have a 2000 chevy 3500 dually with a turbo diesel <sorry dont know what motor it is >but a couple days ago my check engine light came on and then my truck got supper lazy and im not sure what to do is there a way to take the codes out to see what it has without a scanner? i stopped driving it so i dont mess it up more but i need my truck asap what do you guys recommend thanks in advance by the way im in los angeles ca

Can have Checker, Autozone, Napa, or O'Reilleys hook up a scanner and decipher the codes.

BTW, welcome to DB!!!

do the regular scanners work on diesel cars as well?

as long as it is OBD II they should and your truck being a 2000 it is OBDII, just take it to a parts store and have em read the codes for ya and see what it says:humm:

:howdy:Welcome

Yeah just take it to a auto parts store they should check it for you.

WELCOME !!!! And Good Luck with your issue!!!!:U::pca1:

First off, :hi: Welcome!

As for your codes, just like WildBill said, most of the parts stores will check them for you. Once you have the codes, you can find out what the isue is pretty easily. Dont forget we have a code checker right here https://www.dieselbombers.com/codes.php


:pca1::c:

you guys rock!!!! thanks

Should be a 6.5L if memory serves. Good luck - make sure you let us know what you find.

Welcome to DB :hi:

Did you get the code scanned yet?

:hi:

yeah the parts stores dont scan the cars anymore so i had a buddy of mine take it to a friend and this is what he gave me
p0236
p0237
p0238

all i can tell its a turbo boost sensor issue. does this mean its just a bad sensor? where would i find this sensor ? how much it cost ?thanks guys.

bump :ouch:

thanks in advanced guys :c:

i hope that helps a bit

Anything done to your truck, as far as performance wise?

no nothing done to it its all stock but the truck got sluggish from one day to another. should i just get a new sensor or is it the voltage ?

You might disconnect the sensors, clean the connections real good, and hook them back up and try it again. I will see what other information I can find on this..

Im not familiar with Chebbys at all but Ill take a stab at it. Its likely something with your wastegate on the turbo (assuming you have a wastegate) or maybe the turbo itself (which would explain the sluggishness).

Check for vacuum at the wastegate. If there is no vacuum then you have a bad vacuum pump, bad wastegate solenoid, or cracked/broken vacuum lines. You need to measure the pressure of your vacuum system. This is the line that leads from your vacuum pump to the turbo. Chances are the Turbo Solenoid is bad but it can be the vacuum that is bad. If the vacuum is bad, then it is a good TurboMaster candidate. If not, then it is up to you to just change the solenoid.

could dryrott in the vacuum lines cause this?:humm:

Just curious...:pca1:

lol yea


:tttt:

how would i know if i have dryrott? and how would i identify if i have a wastegate. how much pressure should i have on my vacuum system? turbo master candidate ? sorry for the stupid questions i just dont know much about turbos thanks

Hope that helps you some :U:



*edit* -


I noticed your signature isnt filled out.. you truck is a 6.5L correct? All of the information I stated is for the 6.5L TD.. But If I remember correctly, 2000 was a split year, and its possible it could be an LB7 Duramax 6.6 L depending on the manufacture date..

can you tell me what motor is in what manufacture date that way i can identify what i have thanks

nope 01 was first dmax

OK, Thanks for the heads up Danny, I thought it was, but i guess I had a brain fart..

oak, that means that you have the 6.5L TD. So just look over all of your vacuum lines that come off the wastegate, and everything back to the vacuum pump. just a visual.. with it going in and out, it could be any of those things. The Possibly dry rot vacuum lines, bad solenoid, bad wastegate or bad vacuum pump..

Let us know what you find bud!:pca1:

should i be driving it like this? how do i test the solenoid ? wastegate ? and i have to get a vacuum pump tester

oh also will the turbo-master boost enhancer work on my truck ?

Anyone.... :humm:

i had the p0237 on my cummins i changed boots since they were stock and i probably had a leak and cleared the code and its outta limp mode
has not come back yet either
:hi::hi::hi:

All of these issues were discussed on his OTHER thread for the same Codes..

**Threads Merged**

what boots you change?

Hes talking about the intercooler boots

Any progress on this?

yeah i gave up on it and it set me back 2900bucks i took it to diesel tuners in downey it was the boost sensor and a bad injector pump<i think> i felt raped but the truck runs great now i might end up selling it if anyone is interested
