Was exiting my garage to go to work,and there was crap load of snow on the street,so i had no other choice but to go over it(car is lowered),went over it,and MAYBE i ripped one of the wires on the o2 sensor since i popped the code maybe 5 mins after...i do have the zzp header/downpipe combo with highflow cat,and deleted the cat efficeincy code with hp tuners,have the kit on for about 8k now so i dont think its anything else but the o2 sensor wires or the sensor itself..afr is at 14.5-15.5 at idle...any help?

Bad o2 sensor?

 

Thats an O2 switching code, its not a circuit code.

Someone else posted this with that header I think. They believed it to be the design of the header not placing the o2 sensor deep enough into the exhaust stream causing the insufficient switching code.

 

whats up the only code i can find with that number is

P1133 HO2S Insufficient Switching Sensor 1 ECM, PCM

if dont already know what it is. have no clue what it means

 

Could be. if you can drive it go to autozone or advance auto and let them check it

 

i kno this is off subject but i just bought the zzp header dp combo does the sensor always come on and if it does how do u get rid of it

 

you catless? the only way is hp tuners

 

See this thread on the same problem.

come to my work and check it out super... lmao

 

i had autozone check it out,and they gave me a print out of possible problems..they all pretty much focus on the 02 sensor being fucked up

free sensor as well?

 

ill hook you upwith my discount.. or hell get you a better discount at napa... about 50% off

 

This code has been poping up on my car for about 2 months now, im gonna replace the o2 sensor this week , there is a guy on ebay that sells replacement o2 sensors for 40 bucks shipped, yes 40 bucks shipped.

 

I got the same code today as well. This is the first time I have ever gotten it I think it may have something to do with the fact that my CAI has been iceing up so bad the car won't even rev past 2k. This morning I couldn't even get the car to go above about 30 km/h so I took the hose that runs from the blower to the pipe that does down into the wheel well where the air filter is then stuffed a hair dryer into the tube that goes to the air filter and let it blow warm air through the filter for about 15 minutes, then re connected everything and used my aeroforce to clear the CEL and havn't seen it again since although I've only driven like 30 kms on it

 

just so you know when i clear that code it takes about a week to come back. its not one of those codes that come on instead the computer has to read wrong a certain amount of times in aminute for it to come back.

 

I figured as much that's why I mentioned I hadn't driven that far on it yet

 

Did you ever figure out how to fix this problem????????????/

 

i have the ZZP set up as well. i just deleted that code along with p0420 with HPT.

 

Yeah that stupid code made me buy a new o2 sensor yesterday for no reason because it came back im about to delete it with hptuners as well. p0420 always come together with p1133

 

Dood I'm lowered on sportlines and I cruise through deep ass snow all the time:

That's a link to the GM service information document. You just have to put up with some bs adds. I couldn't copy and paste it cause it wouldn't paste correctly. Click the link that says proceed to download, and the click the download now button.

 

i dont have problems with soft snow,its the snow that freezes,and the snow that the snow trucks plow into a small pile and then it freezes and becomes hard...thats what i hate

 

I got that **** covered too:

 

no never got it fixed...i deleted the cat code after i installed my zzp combo(with cat)and its been fine for 4 months till last week

ur front isnt even as low as mine is..my front fenders are about .5" away from my tires..i cant even put a finger inbetween the gap
