Roto-Fab and P0446???

BoilerKB · 09-13-2021, 01:08 PM

Hey all,

I've had my Roto-Fab wet intake, no tune, on my 2019 ZL1 vert for a little less than a year now. Start the car up 9/3 and CEL comes on. Pull the code and it's P0446. I scheduled time to take it into the dealer today but wasn't sure if they would try to blame the intake so I put my stock intake back on (without disconnecting the battery) and now the code is gone. I've seen a list of what can cause this somewhere on the internet and nowhere was any intake mod mentioned. Thoughts? Could my Roto-Fab have caused this? I was going to try and put the intake back on this weekend and see if I get the light again. Thanks for any insights!

I would checked connections and disco'd the battery and otherwise cleared the code and monitor for reoccurance. I think you overreacted, initially.

Wanted to follow up on this in case anyone else runs into it. They ran diagnostics and found that the fuel tank pressure sensor was faulty. So they replaced it with Part number: 13502903 Fuel Tank Vapor Pressure Sensor. Good as new!
