p2a03
So, I went on a trip to Vermont, and in Stowe, there was a road that was RIPPED apart with insane gravel as they were doing construction. There was absolutely no way around this insane road. Mid-way through the 1/4 mile length of hell, my Service Engine Soon light comes on. I'm thinking I throw a sensor. Drive the car back to NY, light still on.
Bring to mechanic my dad has been using for 20 years, told it's an engine bay sensor, but didn't write down the code. Hooked up a reader today from a friend, and it gives me code P2A03 :detected the bank 2 sensor 1 heated oxygen sensor performance was not within acceptable limits.
I have mods on my car, including Berk cats and full exhaust (NOT test pipes). I've read so many posts saying it's due to the cats, but I've never had an issue in the 9 years I've had the car with the sensor. Mechanic said it's one sensor and is easy fix, I fear it being worse.
Any feedback suggestions?
Thanks.
