Well, I got to work today hoping I had an exhaust leak. I checked the up pipe and down pipe to turbo connections. Both looked perfect, but it seemed like I didn't tighten down my down pipe clamp enough. So, I tightened it and hoped for the best.
Just like yesterday, the first minute or two of the test drive seemed fine, and then started hearing terrible sounds again.
Here are videos of the sound:
1. Me pulling a hill
2. Me on flat ground going slow on a side street
Then, add insult to injury I got a new Check Engine Light. P2290 Injector Control Pressure too low!
Did some checking and here is what I found with my monitor:
I found a post with expected parameters and ranges for ICP PSI, ICP Voltage and IPR duty cycle
Key Off:0 as expected
Low Idle: between 577-582 should be 625.5
Operating range is from 0-4045 according to a post I found
Key Off: .25 expected is .2 so that seems pretty good
Low Idle: .75 to .86 expected to be 1 not sure how bad that might be
Operating range .15 to 4.7
IPR Duty Cycle
Key Off: 15 should be 14.84 so that seems pretty good
Low Idle: 42 should be 24 this sounds bad to me
Operating range according to the post I found should be 0-50%, however when I goosed it in park it climbed over 60%. Does that mean that the range actually should be greater and the post was wrong, or that I went out of range?
Lot's of questions:
1. What in the heck do you think that sound is?
2. What do you think is wrong and throwing my ICP pressure too low code?
Grrrrrrr.....getting frustrated. Thanks for the help
