I changed my front o2 sensor twice, cleaned my maf, installed new air filter, changed plugs (which were gray/whitish), and checked my header bolts ...

I had p0133 for months and p1133, is a recent code.

I had these codes cleared and they keep coming back.

I have a injen cai, vibrant header/dp, ottp stage 2 tune but tweaked by 2 members on here on a dyno last oct/nov. I just had 1 of the guys who tweaked the tune, log my car and all is fine...

When I replaced the last o2, which was on for a month and a half, had some good amount of carbon on it.

I dunno what else to do. Think it is the header /dp setup? Anyone have any advise?

 

bump, anyone?

 

Well I have had the same code man for months so it would be nice to know what the deal is I have done all the same stuff as u and I have the ottp long tube header now still have it so know it's not the header dp setup

 

what do those codes mean?

 

upstream o2 codes. responding to slow. im stumped. id rather get it figured out but my inspection is up. so i might have to get them turned off. my mpg is 26.5 and during the summer its around 28.5.

 

1 thing to add is, i had my timing chain tensioner replace. i dunno if that adds any input or ideas to anything ....

 

did u have the stock stuff on before and had the same codes?

 

No had the ca shorty header and a 3 in down pipe when it came on but had that setup for a long time before that code popped up I'm going to be puttin on a new ported and polished head with all new internals so I'll see if that will help lol

 

Replace your Front O2 sensor and both will go away!

You should come meet me one day BTW. Ive tuned dozens of LSJ's now and I will gladly update your car for free Hit me up man!

 

He has replace the o2 twice and I have replaced it twice also so I know that's not the issues

 

ooh sorry, I skipped to the end too quickly then! Lemme re read and edit THIS post

Ok, do you have an exhaust leak around the header/dp? This is for 0133

1133:
Diagnostic Aids

* Inspect the HO2S signal circuit for being shorted to a PCM ground. The HO2S signal circuit shorted to a PCM ground will not cause a HO2S low DTC to set, but will set a switching DTC.
* A malfunction in the HO2S heater circuits will cause a DTC P1133 to set. Check HO2S heater circuits for intermittent opens/connections.
* An oxygen supply inside the HO2S is necessary for proper operation. This supply of oxygen is provided through the HO2S wires. All HO2S wires and connections should be inspected for breaks or contamination. Refer to Body and Accessories/Wiring Systems.
* Using the Freeze Frame and/or Failure Records data may aid in locating an intermittent condition. If the DTC cannot be duplicated, the information included in the Freeze Frame and/or Failure Records data can be useful in determining how many miles since the DTC set. The Fail Counter and Pass Counter can also be used to determine how many ignition cycles the diagnostic reported a pass and/or a fail. Operate vehicle within the same freeze frame conditions (RPM, load, vehicle speed, temperature etc.) that you observed. This will isolate when the DTC failed.



If you want to meet up with me Mike I can log the car and check the wiring to and from the Front O2 to the VCM.

 

yea, nick that sounds good. whenever your free, let me know...

 

This weekend I will be home and working on various projects, if you came up I could take a ride with you and look it over for you. Lemme know if you can, if not we'll work out another date!

 

this weekend is even better. what time and if you want tomorrow? text me if you want to.

 

Did you ever get this problem figured out man just wondering still having this issue every once in a while thanks

 

A slow responce code can also be thrown because of an intake leak somewhere. Check for vac leaks.

 

Anymore info on this issue did u get it figured out I checked for leaks and got nothing thanks
