A few weeks ago I started getting these codes and just re set the PCU and after driving a little it would go back on. Now its on after doing a re set as soon as I start the car. I changed over to a Greddy BOV(and put PSI to 17 spike) and heard with extra PSI it sometimes blows out. Now are these codes for the sensor on the UPP or the intake? I did a search on the other shit site a few weeks ago but I get mixed information with some people saying its the intake and some that say its for the UPP. Does anyone know of a fix for this? I hear some people using the AGP sensor but again in some posts I see they are putting the stock one back in. Thank you for any info. If it matters here are my mods AGP return/reg S2 K&N SRI Greddy BOV 4" TBE
