I plugged my SCT tuner in my car today to get a code responsible for tripping my "service engine soon" light and i came up with the code P1151. Does anyone know what that code means or where i can go to figure out what the code means? Thanks

 

okay i just looked up the code on the internet and the description of the code says "lack of upstream heated oxygen sensor/sensor indicates lean bank 2" Does anyone know what this means exactly? Bank 2 and upstream i am clueless about?

 

I believe thet is for upstream 02 sensor, bank 2. You can always go to autozone and they will check it for free.

 

Does anyone know what i need to do in order to fix the "lack of upstream heated oxygen sensor/ sensor indicates lean bank 2" code P1151

 

ya replace your o2 sensor and reset the ecu

 

So what exactly is the bank thing though? is that in the intake manifold?

 

Naw, you have two banks on the '99-04 GT's. Basically, left and right. There are two O2 sensors per bank. One upstream and one down stream. Do the math and that's four O2 sensors. Basically, the upstreams are the O2 sensors that measure air/fuel ratio in the exhaust and the down streams measure exhaust gas temp. It's way more complicated than that, but hell man. Who really wants a 3 page dissertation on OBDII circuitry.
