Alright guys, i'm looking if anyone has either experience, and or a site that can give me anymore info on this CEL: P2803 - Transmission Range Sensor 'B' Circuit High.

I've read some post saying that the raspiness from some test pipes can cause an unusual vibrations in the transmission mount, that'll trip the range sensor, though the knock sensors detect nothing.


i have a 2006 enthusiast 6speed. again, just looking for someone to point me in the right direction, for either information or a way to fix it, because right now google is giving me the run around and wont give me anything more that the code it self.
car drives fine, all of my maintenance has been completed properly. cheers.

 

I think your scanner farted. There is no P2803 for a 350Z. You may have a code, but I doubt that's it. Remove both of your battery cables and hold them together for 15 seconds. After reattaching, your light should be off. If it comes back on, read it with a different scanner.

 

after listening to the exhaust i realized i had a leak. both in the gasket, and the 02 sensor. tightened the senor down. my gasket looks like it's already shot. so gonna quick fix it with some high heat rvt, and get a better gasket this coming week.
