Thread: o2 sensor code 33?

so the other day we were drivin down a hill, in 4th gear just coasting and the check engine light started flashing, clutched in an it went away... so pulled the code and this is what we got..



the thing is, we're not using a narrow band at all, we're using the wideband instead, i've tried to find if i can disable the stock one, but it looks like when you use the wideband it does it for you??

so is the code coming from the wideband thats hooked to the breakout box? maybe from vibration? or whats the deal?

Do you have the stock narrowband checkboxes disabled in the closed loop tab?

That is the first time I have seen this code pop up.

Anytime anyone needs help diagnosing something, please email an unfiltered log (TCL) and TCD to John and myself. To capture an unfiltered log, make sure all Recording Triggers on the Logging Settings dialog are 0.

Thanks,
Dave

I believe so I'll double check.



Uhh I dont understand? The check engine light only stayed on for a split second so there was no time to record and i don't use the on board stuff ever

It is a lot easier for us to help diagnose an issue when we actually have the data in front of us to look at.

I know it is difficult sometimes to catch problems as they occur but if you do happen to get a log when something like this happens, definitely shoot it over to us.

Yes sir, i will try to understand what dave was sayin when i have one of the laptops in front of me

Ok different car but having similar issues, I'll be drivin cruising steady throttle an all of the sudden my check engine light comes on, I let off gas pedal an it goes off.. When I check the codes I get 4, map, iat, knock and o2 sensor.. I'm not using the map or iat but had them enabled for logging purposes... I think I was able to capture a log while the CEL was on, I will email it in the afternoon..

Enabling the sensors also enables diagnostics for those sensors. Check the min and max voltage settings for each. You can log the values from the sensors without enabling them. See NEMU ADC Inputs tab on the Settings dialog.
