today I changed my T-Stat and did the blue spring upgrade.
I put in the coolant and went and got my AE so i could monitor temps and such. Checked for codes and found P0402 EGR flow excessive detected and P132B turbo/super charger boost control A performance.
is this a sign of a turbo cleaning in my near furture or a EGR valve or both

 

Maybe Both

P132b can be a PIA

Post these gauges at KOEO

BARO
MAP
EBP


and what Kinda Boost you see at WOT???



P0402 EGR Exhaust Gas Recirculation Flow Excessive Detected EGR valve, EGR position sensor bias, EP sensor bias

I am Leaning towards a Bad EBP/Plugged/DIRTY Sensor causing Both DTC will see what your readings are though

Might be good to Clean EBP Sensor and Metal Tube that feeds sensor from exhaust manafold

 

can i post a excel spread sheet in my posts?

for whats its worth when i changed my t stat i checked the 45 * fitting and the sensor but didn't check the whole tube from top to bottom

 

I know paying memebers can post that stuff

You might be able to Load it into a Usser pic album and post it

if not just post BARO-MAP-EBP at KOEO and Low Idel and High Idel(2500rpm) ALL In PARK or NUETRAL and we should be able to see whats going on here

 

this is from a data log from AE and not on a cold soakat koeobaro 13.05map 13.02 ebp Unable to Learn Exhaust Back Pressure Due to an Engine Sensor Fault (Bit) [0 - 1]at 2591 rpmbaro 13.01map 14.75ebp same as above

also about 21-22 lbs boost at WOT

 

That pretty much tells ya your not getting any reading from the ebp. Bad sensor or sensor wireing.

 

I would hazzard a guess that since he has an 04 truck it has an 03 engine and the EBP is an inferred value.

To the OP: Is your ICP sensor on the passenger side valve cover or under the turbo?

 

P132B is a code related to the calibration from the recall 06E17 (part of the Inferred EBP strategy). It means that there is a problem with the VGT system. P132B is a fault code that is set if the required boost levels are not achieved during a learn cycle or at specific speed fuel demand points. This code indicates that there are issues with the turbocharger, MAF sensor, MAP sensor/hose, IAT2 sensor, intake leaks, or exhaust leaks, etc. Frequently it is a sticking turbo issue. This code can also throw a P0401 EGR code - maybe also the P0402 code as well.

 

My bad didn't look at the truck year

 

My plan of attack it to check all the sensors mentioned and for exhaust leaks.
I work nights and sleep days so it won't be until next weekend that I can do this.
I will post back what I finde. Hopefully all of you can stick with me on this

 

If i had to guess I would say that your EGR is sticking. A stuck egr will also throw 132B. Pull it out and clean it, clear codes and do a VGT relearn.

I looked for the icp sensor on the VC but did not find it. But did find a sticker that said I have a YM 03 engine

 

03 ICP and IP Under Turbo The Fun ones

But that Means Inferred EBP But Unplud the sensor see what Happens EBP is bolted to the thermostat Housing

You Need to Look at
MAFV
BARO
MAP

Pull and Clean EGR Valve

 

so today i did the following..... pulled the EGR valve and cleaned (had a bit of carbon) pulled the IAT2 sensor and cleaned it was very bad
checked and cleaned the MAP and MAF. And a AFE intake delete.
hooked up AE to check for codes and the 132b and 0402 code had not come back
also did a data log and i will try to attach but if if doesn't i can repost with data.

 

Anyone. Blade , bismic
