Where can one find said step by step guide??
That kinda sounds like why mine won't run. Green light comes on starts boosting . But if u are heavy on the pedal or going up a hill it falls flat on it's face. Kinda irrelevant but can someone help me out i just bought the truck and joined the forum. Drove the truck for a hour so far. The rest of the time it's been in the shop and they haven't come up with anything besides it happens when it's hot . Tried swapping sensors and even the ecu with no chanhe
Do you have a boost gauge? If so, is the turbo boosting over 14psi? If it is, this is definitely your problem. The fuel cut is very abrupt and noticeable. The behavior you described in your other post with regard to the turbo light going off and check engine light coming on makes this almost 100% certain.
Perhaps someone put a boost controller on your turbocharger to increase the boost? If not, it could be that your waste gate has failed, is not connected, has been modified, etc. The waste gate is what controls the turbo boost level by allowing exhaust gases to bypass the turbine.
Post a picture of your engine bay; specifically the area on the turbo side of your engine, and we can help identify if there are any obvious problems.
I recommend you install a boost gauge regardless if you don't have one. T in to the vacuum line that comes out below the throttle body, as this will give you accurate manifold pressure.
It will happen more often when hot, because hot air produces higher boost (air expands when hot).
It really surprises me how much difficulty auto shops have dealing with these motors. They are very simple really. Checking for an over boosting condition on a turbo engine should be dead easy for a shop.
Where are you located? BC is a big place.... there are lots of us around the province, maybe someone local to you can give you some more ideas.
Just got the truck back today will take pics tomorrow. He had a boost gauge hooked up on test drives and said it was making 10psi then dropping off under load. I was also wondering if the cts is supposed to have the same plug as the crank sensor .square hole with a notch . I went to lordco with the part number I got from the mechanic and it came up with a completely different looking plug. With 2 prongs. Is it possible to have them switched?
I'll have to take a look tomorrow. I'm also on Vancouver island
I'm in Duncan so I can try and get the codes off of it i found a plug not connected that comes off the sensor he told me yo check. But it's got a plastic cover that it's plugged into but not anything else I'll see if I can post a pictureI'm not sure which sensor you mean by CTS.
Good that he was using a boost gauge. I guess the problem is not so simple then.
Have you guys pulled the codes out of the computer? Any time a check engine light comes on, it stores a code identifying the problem. It is possible to pull these codes by putting a jumper in the diagnostic connector and watching the check engine LED blink a pattern.
If you are in Victoria I can help you with this part. (Assuming the mechanic doesn't know how...). Or if you are somewhere else on VI, then I can describe the procedure to you.
