Hi,

Today I received a P2237 code. According to the codes list on this forum:

P2237
HO2S Pumping Current Control Circuit Sensor

This is the second time I've received it. The first was quite some time after having the CAI installed. The second time was about a week after the Dejon IC pipes were installed. Not sure if it's related to any of that though. That's what I'm asking here for.

If I take the car to the dealer, will they tell me it's because of the CAI or IC pipes? Will they tell me it won't be covered under warranty (in Canada) if I need something repaired or replaced? Should I just clear the code and ignore it?

Thanks.

Does anyone have any ideas what could be causing this problem? I keep clearing the code, but it just keeps coming back after a few days. I'm starting to think it has something to do with the re-tune I have as it never happened before that. Lil Goat, have you had any codes with your tune?

Sorry to revive a dead thread on my first post, but I'm also in Calgary and have this code that also pops up now and then. Currently, on my automatic 2008 Sky RL, I have a 3" intake from Custom Tubes Inc., and the downpipe and race exhaust from Solo Performance.

Did you ever figure out what was causing the code?
