P3497 if I don't let engine warm up in cold weather

So a few years ago a replaced the front VTEC solenoid (and alternator) due to it leaking oil. Ever since then when it's really cold outside and I crank then engine it will throw the P3497 code if I don't let it warm up for a few minutes. If I shut it off and clear the code with a scanner, then crank it back up it runs fjne.

I thought maybe it was the cheap oil I used so last time I changed the oil, I used the higher quality stuff, but the issue persists. It never happens when it's warmer weather.
