when i am logging my car with hptuners, this code is coming up as pending and immature.
However, it is not illuminating the CEL on my instrument panel. I know this is the supercharger inlet pressure sensor and I know where it is. there is nothing visually wrong with the sensor or wires.

Also i am having hesitation and a lean afr of 16.5 when beginning to build a little boost around 2500 rpms.

anyone else have this problem and how do I fix it?

 

Get in the PE tables and add fuel where you are lean first off. See if that helps the code.

 

well I really dont think I'm in PE when this happens since im only at maybe 2psi and around 2000-2500rpms. I have PE engagement at 2000rpm, 120kpa, and 50% throttle.

It feels like almost lean tip in, but i havent changed anything and i wasnt getting this before.

 

welp, I gave it some more fuel by letting it engage PE a lil sooner. I also pulled a degree of timing out of that spot. I will try that and see what it does.

 

That seemed to work. Although I think dumping it into PE earlier is just a bandaid fix for some fueling error.
The p1182 didnt come back either...

 

Going lean will cause the hesitation due to KR - retune your VE and MAF. You can try setting Dynamic Airflow down to 2k and it will make it pretty obvious which it is.

Did you make any changes recently that caused this or did it just randomly start happening?
