Having problems with your 2003 Toyota Avalon ?
I have a 2003 Toyota Avalon that needs an oxygen sensor based on a code that says 02 sensor, bank 2 sensor 1. I was told this is on the passenger side upstream of the cat. Is this accessible from the engine compartment?
No it is not u have to get under the car to acces the o2 sensor and make sure u do not strip the new one it will cost u alot more money.
