From what I've researched this seams to be a common issue after installing the test pipes

 

ashram, you need to b aware that the SES light is just a warning to tell you that there is a problem.

It's not a thing on it's own, it doesn't mean *anything* other than the system has detecting a parameter that's not in the normal range.
It has HUNDREDS of codes that will trigger the same light.

I get the impression that you think this is just the 'normal' light thrown by the rear o2 sensors after installing TP's, it is not, this is a more severe problem that you need to address directly.

 

Thanks fore the warning, im aware of what the exact code is im getting (P2A00,A/F Sensor Circuit Range/Performance (Bank 1 ,Sensor 1) when i use cipher to scan fore ses codes, ive gotten this code 3 times already and i just finihed clearing it a couple of minutes ago.

As of right now i haven't felt any loss of power or a decrease in mpg, this particular code seems to plague a lot of z owners and seems to be a pita to resolve.Ive so far read owners having to remove there test pipes and go back to factory cats which im not gonna do or replacing the sensor only to have the ses light come back on fore that same code.

my tuner is out of town at the moment so i'm definetely gonna see if there is a way to get around this, i don't wanna go to the stealership cause there just gonna charge me 95 bucks to diagnose a code i already know.

I'm gonna have the shop i go to test fore any type of leaks on the test pipes i did go over a bump kinda hard a couple of weeks ago i may have cracked a pipe but im thinking this is highly unlikely. I read that could trigger that particular code as well.

I appreciate everyones advise.

 

when you get a code for the front O2 sensor, it means that it is going bad and needs replacing. You dont get front O2 sensor codes from test pipes.

 

I'm gonna go ahead and order that sensor today

 

Ok so i took the advise of my fellow members and got the bank 1 sensor replaced. the car definetely pulled better after the new sensor install , but as i feared would happen the ses light came back on. withthe same bank 1 error. At this point I don't know wnat could be triggering that same code.

 

Exactly the same code?

What year is your car, usually there is more than one fault or cause of the code.

 

what is the number of the code? "p" what?

 

P2a00

 

The car is an 07 , the error code is (p2A00. a/f sensor circuit range/ performance bank 1 sensor 1). This is the same code the car was throwing before i replaced the sensor.

 

Bad wiring or ECU. Do all the tests outlined in the FSM to determine.

 

 

To the OP. When I got that code, I went ahead and replaced both cam sensors just to be safe. After doing that my code went away.

 

I had CEL/SES light too. It was due to stripped o2 sensors from my stock cats, so my mechanic just put dummy sensors in its place to block the hole.

I just got UpRev tune today and the tuner disabled the sensors. No more CEL/SES. Make sure you get the code deleted and sensor disabled. Simply deleting the code will cause it to throw again. Your tuner should be able to uncheck the lower o2 sensors while he is tuning.

 

He isn't having an o2 sensor problem, it's the cam sensor.

 

Thanks fore assistance guys , something tells me this is gonna turn into an expensive fix, a bad ecu, bad cam sensors another tuning session lol. If the cam sensors where bad should'nt there be an ecu code fore that ?

 

Which sensor did you already replace? The bank 1 code is for the cam sensor(s). Not sure if this is what you replaced but they aren't too difficult.

 

I had bank 2 and bank 1 sensors replaced, both went bad coincedently after i got my test pipes installed

 

You need to download the FSM for your model year and look up that code and follow what it says to do to troubleshoot it. Or you can just keep replacing parts at random...

 

I had my tuner show me how to remove the bank 1 sensor error code thru a reflash by using osiris. hopefully this keeps the ses light off. my car runs fine ive already had both bank 1 and bank 2 sensor replaced. ill see what happens in the next couple of days
