Alright guys i keep getting P0133 code..i replaced sensor b4 cat on driver's side...but i keep getting the code after i reset it..i mean is this a reccuring problem?...i have read that some cars are more sensitive than other on this...i gutted my left cat..but the right is not gutted yet. I have 02 sims...is this a bad 02 sensor? i think i'm going to switch the top two sensors and see if i still get the code...what do yall think?

 

i doubt its a bad O2 what does the definition for that code say?

 

P0133 Heated Oxygen Sensor (HO2S) slow response Bank 1 Sensor 1

I have the same code now. It cames and goes actually.

At first I had codes P1133 and P1153, insufficient switching on both front O2's

I changed my front O2's and the codes went away. Now about 2 weeks(400-500 miles) later, I got code P0133 on and off.

My gas milage is pretty good, so I don't think I'm running rich. I'm beginning to suspect something like a bad wire or ground wire or something jacked up in the PCM.

your 02s are going out changed mine then the other side went out......change them both...

 

Slow respose could be a bad O2 or you could be running lean for some reason too. that could trigger the code if the computer isnt able to get it back to 14.7:1
