Hey everyone,
I have had a P2A00 code for about 7 months now and have recently found that my Bank 1 air fuel sensor(which has a code) is getting voltage when the key is on with engine off. Now Bank 2 air fuel(which does not have a code) is not showing any voltage with key on engine off.
This clearly has something to do with my problem but what is causing this? any ideas?
I have replaced the sensor with OEM and have smoke tested the system to no avail. Cleaned MAF sensor and watched with scan tool not showing any problems. I have no exhaust leaks, so if anyone has any ideas im all ears.
