5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Any symptoms other than the light? Rough idle and poor fuel economy specifically? 67k is pretty low mileage for the sensor to go out generally... But on a 4 cylinder bank 1 sensor 1 should be the one on the exhaust manifold right on the front, there's a #2 sensor after the cat. Doing some research here by searching the forum for that code it looks like some people have found the problem started from a bad PCV leaking oil into the intake, it may be too late for the sensor but you should check out your intake so you don't ruin another one if it is too far gone.

Last week I got an oil change at the dealership, a few days later I have a check engine light come on. It stays on a few days then shuts off. Then comes back on. I take it to the dealer to have it checked and they advised that it was the oxygen sensor.
It says oxygen sensor pumping current circuit low (for a/f sensor) (bank 1 sensor 1)
Then I go to advanced and have them run the same thing and it also says oxygen sensor bank 1 sensor 1.
Dealership said nothing done during an oil change would have cause this.

On my Dads 2003 Camry the o2 sensor craped out around 40,000 miles. He went to the gas station and filled the tank and when he restarted the car the check engine light came on. Got the o2 sensor bank 1 sensor 1 replaced and that took care of the problem.

Thanks for mentioning the possible pcv problem. Will check it out on my 2003 Camry. Don't want the o2 sensor going bad on me again. It definitely should have lasted longer. I used to own a 1989 Camry and at 276,000 miles it still had the original o2 sensor. They just don't make them like they used to.
Would this be oil where the air intake filter is? Checked the actual air filter area and it is clean.
My car after the oil changing is leaving a little oil on the ground where on my front passenger side of the vehicle. This is new since the oil change, very new and noticeable was going to wait and if it continues or was just for a short bit right after the oil change.
Took the plastic cover off the engine and looked behind it on the passenger side and think found what your were referring to on the PCV. Small hose up high that runs into the air intake part of the vehicle. It looks good and dry but directly below it near the ground almost is an identical hose that half of it is wet along with the aree below it and that is about where oil is leaking on to the ground from my car. Not sure if it is a spill from an oil change or a leak.

I'm not real familiar with a 2004, but the PCV valve should be either stuck in the valve cover or in the hose coming from the valve cover. According to a post I'm reading it should be under the engine cover, passenger side of the motor on the back of the motor pointing towards the firewall, it should screw in. From where that hose ties into the air intake and down into the engine from there is where you'd see oil if it was an issue inside the intake hoses.
From your description that's where you were looking, did you try wiping the area directly below the PCV valve/hose? If there's oil there it's probably a bad PCV. Frankly it'd be pretty unlikely to get a spill in that vicinity doing an oil change, the filter should be on the front and the fill is on the top front, it's possible they over filled it, or it's possible it's just a coincidence that the PCV crapped out at the same time if that is indeed what happened.

Bank 1 is ALWAYS the bank that includes cylinder #1, and sensor #1 is the first one before any catalytic converters, cylinder 1 should be the leftmost cylinder looking from the front (or furthest to the passenger side if you prefer) on a 4 cylinder Camry.

Did they clear the code when they scanned the car? It will take a few days before the feedback system tests will complete before the code would set again. It's also possible it was an intermittent problem, but I'd definitely keep an eye on things to prevent damage, particularly to the catalytic converter, if there's still a problem.

It worked fine until I fixed it!
