Keep getting code P0133
Hi everyone. I've been struggling with the P0133 code "Oxygen Sensor Circuit Slow Response" for a couple of months already.
It seems that it could be anything causing it. I ride a 2009 Mitsubishi Lancer ES Sport package (USDM) stock with some 172,000 miles on it.
I checked for any leaks at the exhaust, got nothing. Changed the Sensor 1 Bank 1 O2 sensor (before cat), still got the same code. Changed spark plugs, went for a throttle body maintenance, nothing. All maintenance to date. Same code still there.
It would help me a lot to know what can be causing this code to keep showing up. Thanks in advance!

Have you got the P0133 fixed ? it maybe also has something to do with catalyst converter ? i had CEL P0420 with a new aftermarket cat . then i got rip of that by installed a defouler. but now i have P0133 .
I am trying to figure out if i need a front O2 sensor or get a OEM cat
