Hi Scotty I have a 2003 Toyota Camry with 176k I had the engine light come on an I got the evaporative emission control system leak detected (small leak) also I have the code for the O2 sensor bank 1 sensor 1 ,my car when I see on the gas it doesn't get up an go like it should ,,it takes off slower an once your goin you can feel it kick in an starts taking off faster almost like it's not getting enuff gas or something until your at like 20mph or so then it just kicks in an will accelerate fast.sometimes it will take off fast without the loss of power but most of the time I can push it to the floor an it takes off slower an then kicks in you can feel it when it kicks in cuz it starts accelerateing fast.so my question is what's your thoughts on these codes I got ,what would be your guess being I got both of those codes ,could it just be the O2 sensor or is it multiple things one was that small leak in evap system ,could this also be causing my acceleration problem .thank you so much for your help.im out here in Tomball ,H-Town..so thank you for all your help over the years from a fellow htown resident ...Texas boys are the Good ole boys .especially the old schoolers like you Scotty they don't make good honest people anymore like they did in your day an age .my father is probably from your era an he's one of those good honest people ,anyway thank you for all that you do your the best Scotty...your much appreciated. Sincerely ,,Mr Randy Rhodes

Start here: buy OEM GENUINE TOTOYA gas cap. First. And do NOT buy a Chinasium one. Amazon online and McGeorge Toyota Parts online have them too. Drive around w/ OEM gas cap-- properly snugged down-- for a while (days, a week). Re-scan. If P2238 still shows up AFTER you cleared your Codes, then yes, you're looking at a new O2 Sensor.
