P0037

Jordo! · 03-03-2011, 10:07 PM

Hey there,

Seem to have just gotten a P0037 CEL code -- indicates low heater circut on bank 1 O2 sensor 2 (post cat).

Possibly fried due to test pipes???

Anyonw else had this issue?

Any chance the dealerhsip will warranty it, or not with TP's on?

Thanks

I can say they definitely will not warranty the o2 sensor if they see test pipes, especially when the downstream o2 sensor bears the brunt of having no cats. I would install your stock cats if you plan on trying to get them to cover it under warranty as o2 sensors are not cheap!

Yeah, that's what I figured...

Has anyone else had this CEL before? Search turned up nada.

I would clear the code and see if it comes back again..... which it will if you have a faulty O2 sensor. There was a thread here a while back, but I couldn't find it either.

I did and it did

Dammit.

I'll search for that then... thanks

Had to use the Google search as "o2" won't work... nothing clearly points to it. Seems no one has reported a P0037 before?

Sonnovabitch... I'll have to see what one of these costs just in case I need to rreplace it. What a ******* pain in the ***.

Try the 350 forum. But you will likely need to replace the 02 sensor.

Haven't seen it on the Z, but just had a a variant of it on my truck with P0161. Check the wiring to make sure nothing moved and melted, otherwise it could be a bad sensor. The good news is that sensor is very easy to replace yourself and only costs about $100 from rockauto.com.

I found it for $150 -- I'll have to shop around some more. Is it the same p/n for the 350 and 370?

Is this a common problem? No one on here seems to have had this happen yet?

EDIT: Wow -- thanks! Yes, found it for $92 and change plus shipping. Like $102 shipped! Awesome!!!

EDIT #2: Wait -- this is probably generic part -- just as good (which I guess means nothing considering the new OEM part failed

)?

You would find more information if you search po037, that is p o not p zero. Other than that, replacing the o2 sensor should fix that problem for a little while but I would be worried about the test pipes killing it again somewhere down the road.

Rockauto.com has the NTK which is a good brand for German and Japanese cars, equivalent to Bosch. That's what I used as a replacement on my car when the O2 sensor got destroyed during removal from the stock cats, no problem so far.

Thanks, guys - ordered

Yeah, I'd kind of like to know if I have to worry about this continually happening again...

Thanks

I wonder if this is just a random flukey thing then...

Haven't heard of anyone else having this issue with TP's.
