I know why my car is having the problem with the insufficient switching, as i have forgotten to switch off at least 1 DTC that controls the air pump and the tests..(could be wrong about that..)

can anyone list ALL of the DTCs that deal with passing the readiness tests...
and i'm sure several others would appreciate this.

the thing is I have had my headers on since I practically got the car(5600miles until about 20kmiles, and it didn't start giving me the codes (attached) until several months ago after I tried/attempted to cut the readiness tests off(so that they would read ready no matter what)

Those codes that I'm getting ar p1133 and p1153, which are in the DTC MIL Enablers. P1133-O2S insufficient switching bank 1 sensor 1
p1153-O2S insufficient switching bank 2 sensor 1

I KNOW it has got to do with the AIR PUMP cycle and testing for the heaters, as this did not happen until AFTER i changed codes and turned things off to try and get the readiness tests; it is not the fact of losing heat due to stainless steel headers.

****, it was too damn hot.

with my 3.73 gears i ran a bets of 60ft 2.2 109.46mph @13.21 (that was my best mph ever though)

it was 95+ F at the track


howd you stuff go with the readiness tests and getting everything cleared

theres gotta be something that i'm missing

i drive the car after flashing a tune in it, then turn it off. then go and drive somewhere else, and its about the time that i get to cruizing or getting on the throttle then off and the SES light comes on with the p1133 and p1153. it has got to be something with the air pump or something familiar

Sounds like you need to change the DTC Processing Enabler for "O2S Circuit Insufficient Activity Bank 1 Sensor 1" & "O2S Circuit Insufficient Activity Bank 2 Sensor 1" to not reported.

from reading that it seems to be my problem
in doing that(changing to not reported), would it keep me able to run closed loop?

also, Alvin(pcmforless) was talking to me about reading in the scantool for where my problem could be. and by adjusting B4105 - 02 switch point i would possibly be able to get rid of my problem

You'll still be in closed loop, but you won't know by an SES light when your O2's take a $h!t. It could also throw off your light throttle and idle air fuel ratios. The solution I gave you is a temporary fix. The real fix is to get some O2's that aren't so lazy. They're expensive, but I'd go with new OEM Vette rears....or save a buck and get the Bosch versions (13111).

i ended up buying the corvette exact rear 02's and funny thing is the SES light happend more frequently

SSpdDmon

iTrader: (10)

I was thinking about getting them too since everyone swears by 'em. But I've yet to run into a problem with the ones that came on the car....and I even did the jenkity Pacesetter extensions instead of buying the pre-fab'd O2 extensions. I wonder if this is more of a myth??? Do you still have your stock O2's? Might want to give them a try...

ZL1Killa

iTrader: (17)

yep, put the stock 02's back on as the damn corvette sensors were messin up more often. So don't waste your money(~$160-200 i think) I might put them on if mine ever die..but thats about it.

(for readiness tests)My whole goal was to trash the air pump and all that crap. well, my buddy has a 2000 trans am and he can have two codes(the air pump and 02 heater)
well mine is an 01 so i can only have 1 code not ready under the readiness tests.....at this point i'm almost like forget it, the stuff can just stay on the car and do its thing.

What i'm going to try over the next few days is cut on all of the air pump crap and all of the readiness tests and see if I have the p1133 and p1153 codes any.... and if not then its the air pump stuff. see the car used to be fine, and it never had this problem, until i tried to get rid of these readiness tests

ok , made a log and watched the CL modes; I have he scan log and here are 2 attached pictures from the log. I'm going to try and attach all i can.

its the p1133 and p1153 codes, insufficient switching. so somewhere i'm pretty sure i can change the 02 switchpoint table B4105 and i won't have this problem.
I would like to not have to cut the air pump and all that fun stuff back on; as with all of this off this is what led to these codes(at least from changes I have made in the past 3 months) since the headers have been on the car since i bought it and for 20kmiles it hasn't done this.

anyone with prior expereince or knowledge would be appreciated.

c'mon guys...lol i'm trying something today from those logs...idk if its going to work tho

ZL1Killa

iTrader: (17)

now, after the change i made i'm only getting the p1133 - 02S Insufficient Switching bank 1 sensor 1.

also in this picture what in the world is going on here? My bank 2 sensor 1 just went to under .1V and bank 1 sensor 1 stayed at .8?!?

on other logs it also did this, and sometimes BOTH banks sensor 1's dropped to .1V? is this normal at times?

ZL1Killa

iTrader: (17)

also, hooked in parallel with bank 1 sensor 1 is the narrowband gauge that i have. now, whether or not this is causing the problem idk. the gauge and everything has been wired in for a while and it hasn't give us any problems... but cars are cars...

tomorrow, i'm going to install a rear oxygen sensor and put the narrow band on it and run the car tomorrow and see if i still get the p1133 code. i don't understand why the bank 2 sensor 1 went away and not bank 1 sensor 1.

the narrowband gauge is the only thing i can think of though, that would possibly cause bank 1 to be doing anything weird, as now bank 2 is fine.

and i'm now solving my own problem and talking to myself on a message board......

LMAO!!!

I have these same 2 codes. What ended up working for you...if anything?

SSpdDmon

iTrader: (10)

Did you try replacing the stock O2 sensors with stock, direct replacement ACDelco O2 sensors? Did you try searching in EFI live (search button above folders with all parameters) for P1133 & P1153 and changing the DTC Processing Enablers for those to "Not Reported?" The first suggestion as I said earlier is the real fix, the second is the band-aid.

ZL1Killa

iTrader: (17)

the vette sensors don't work. I'm telling you that it has got to do something with the airpump AND OR the fact I have that narrowband hooked in with it. the car used to be fine and was fine for 20k miles after headers. so its got to be something with that damn air pump or the narrowband.

i have not had time lately to change anything, hopefully this week will be less busy and I will take that narrowband off and see what it does.

once i get somethings sold I will be buying a lc-1 and selling my lm-1. i don't have the cash now to just buy the lc-1. and i will hook the lc-1 into the narrowband.

i will keep you guys posted, for those that have this problem please post up here with your problem, or PM me. I want to know all that have this problem

I wasn't refering to the Vette ones this time. I meant as if you went to the parts counter at the local Pontiac dealer and said, "I need two new O2 sensors for an '01 f-body - front left and front right."

ZL1Killa

iTrader: (17)

whats the difference? aren't the vette heaters stronger? and its not the temperature of the sensors, its the switching.

ZL1Killa

iTrader: (17)

alright here is a little update. still keep getting the codes triggered BUT I only get p1133 here again, which is bank 1. and I have now gotten that twice in a row; bank 2 seems fine.

what exactly am i doing when i change the switchpoints? I have set at 16 - 580; that is the only change I made to get where i'm at now.

I just made a tune now, to go a program in the car and see what it does.
