So this is what I got, any ideas????
Codes
p0137,p0138,p0139
p0157,p0158,p0159

Codes read off dash command app via obd2 with screenshot below

Got these codes shortly after fast intentions test pipes/exhaust. But I think the real culprit is the new Bosch oxygen sensors that I bought to put in the new test pipes since the ones on my z1 hfc WERENT coming out.

What I have done:
I have reset ecu, checked for any exhaust leaks (none), checked connections and visually looks ok on oxygen sensors,

Possible blown fuse or something like that?

Your correct on the bosh. Oem is what you need. If it was tp itd be p0420 p0430.

I think it's the test pipe vs hfc issue. I think I read somewhere you need extended bung to remedy the codes.

Ordered 2 oem from z1 tonight, I'll install tomorrow night when I get off work. Fingers crossed!

New o2 sensors fixed it. Thanks!

Lesson learned. Only buy oem. I figured Bosch was good enough but my car didn't like it one bit.

Part #: 226A0-ET000

paid $150 each for oem. Not sure what the others cost but wouldn't matter they didn't work at all

Good job brother. I made that mistake many years ago!

I wish I would have seen this a week ago. Glad you got it resolved.

I used Denso O2 sensors when I did my headers and test pipes, no issues for a year now. Just a heads up for future peeps.
