Is this problem my 02 Sensors or what?

Hello everyone I've been having a check engine on for a while now and it started off with just one code for an 02 sensor after I stomped on the gas one day. Stupid of me to do but hey I'm sure a 4Runner can handle pretty much any abuse as I've come to learn lol. It's a 2003 and I figured I'll just switch out the sensor when emission time comes around. But then it started to throw me more codes and now I have 5. I take care of the truck and all codes are emissions related. I have P0430, P2241, P2238, P0430, and PO332.... has anyone came across this? If it's my 02s let me know... I will switch them out with original Denso Sensors.

How many miles and when is the last time you changed sensors? Sensors are wear items and can deteriorate before the actual fail. I just swapped out all 4 on my 4.7L Tundra when I got one code and the truck runs so much better. Get all 4 Densos and put them in and keep driving.

Stomping on it probably deposited some debris on the sensors.
Try clearing the codes and see if the codes come back.
Also try checking the Air/Fuel fuse in the engine compartment

It's a 2003 4.0 4Runner... I have noticed a decline in gas mileage... hope it doesn't have anything to do w my cat as one of the codes suggests. Looks like I'm gonna have to scoop out some money for the Sensors. Unfortunately they're so expensive

Will do... most likely gonna have to change all the 02 Sensors which is gonna be expensive as heck lol
