So I recently got a protune and today saw a p0140 code pop up. I had read that it probably means something's wrong with the rear O2 sensor. Is this dangerous? Should I rush to get it fixed?

Thanks!!

 

same thing happened to me ...I called and he said its because he didn't use the new tethra.

 

Damn man... How did you end up gettin it fixed? Or do you just clear it when it comes up?

 

I just ordered a Tactrix cable so I can maybe look at the tune on my laptop or maybe reflash another tune on there. I have inspection coming up in a month and it wont pass with a CEL.

 

its a permanent CEL and has been on for a couple days straight now.

 

That sucks man. I got tuned at Ivey and he did a really good job. I had asked him to turn off the rear O2 sensor and he did as far as I know ( I don't get the code telling me that my cat isn't working) But about a month later ( now) I got this code. So I cleared it, trying to see if it comes back on quickly, or if it takes another month to come one, in which case I have no problem clearing it every monthish. Just not looking to clear it every day haha. ( Have driven about 2k miles since the tune as well)

 

If there is an issue let me know we can handle it no prob.

Let me know what you end up doing with it. Im pretty sure it needs retuned all together though?

 

Fran who tuned your car?

Sean

 

Sean: I cleared it last night and no sign of it yet, let me see if it was just a fluke, if it comes back on I'll give you a call. Thank you for the excellent customer service by the way

 

No prob let me know I am there working all week.

Hopefully that clears things up! At least you know you have a good reliable tuner! Just doing some forum stalking haha.

 

I was at Buschur

Nothing bad I can say about the tune though, it is driving very smooth now

Wow.. that sucks... should have just come over to Ivey! haha

 

I'm sure it's a simple fix that can be done by any tuner. Good luck in getting it resolved quickly!
