p1153 code keeps coming up

[ruggerisa]

Hi everyone, I recently just installed QTP long tube headers and y pipe without cats and electric cutout. I had the car tuned with the cutouts closed and it was running great. About a month later it through a p1153 code (heated oxygen sensor- Bank 2 sensor 1 insufficient switching), I switch the front o2 sensor and cleared the codes and about three weeks later through the same p1153 code. Does anyone have any ideas that could help me?

What brand did you use to replace the old O2 sensor?

bosch

I would recommend using A/C delco or GM brand. I had problems with those before. Also before replacing have the code erased, and then have a scan tool moniter the wave form and MHz of the sensor. Secondly check for any leaks at the header gasket and header and also the wiring harness to the O2s. Don't go to your local vat zone either. Have your tuner look at the wave form or local repair shop.

A lot of people myself included have had this issue and after trying the bosch sensors and the oem denso brand I can honestly say neither fixed the issue. The densos are def better sensors (I could literally watch them switch faster than the bosches on the scan tool) however they still gave the code. It has to do with the sensors being further downstream in the lt's and thus causing them to run colder. Most people just turn the codes off including frost and thats what I have done... No adverse effect on performance.

Okay I never changed the sensor and about a week later the check engine light went out, then the fallowing week the light came back on. Should I be looking somewhere other than the sensor to fix the problem?

Could having an 1153 code cause a low rpm miss/detonation? I guess I don't understand how a heated oxygen sensor insufficient switching could cause spitting and sputtering at low rpms??

Oh, also, how do you erase the codes? Thanks.
