Thread: code p0133

hey guys i keep throwing the code p0133 oxygen sensor bank 1 sensor 1 slow response....i recently replaced this sensor with a bosch....could be bosch but i dont think so....anyone know what else can cause this? i did have my canister purge solenoid break and i superglued it back together and i heard a bad CPS can cause this code? i also have a deleted egr? any ideas? i used to throw alot of oxy codes because my pacesetters leaked but they are now wleded shut so i know its not this...i keep gettin this one code p0133 and of course the rear o2 and egr codes but i know what those are from...no cat and no egr lemme kno if anyone has had this code and what it was i think im just gonna get a denso i heard bosch sucks....

Many here recommend Denso, but as far as the del-EGR or the no cat being the culprit, I dont have either one... and have never had that code.

If you have a new o2, I would not think thats it.

I say.. CPS.

I got a Denso.

Have you had the code from the EGR permanently removed from the PCM? If not...try that...
