Need help solving p0154 p0134 Car stats:
1997 M3
2002 f-body pullout
pcm tuned, rear 02's deleted
cammed
vorshlag LT's with o2 sensors placed right after header in a temporary piece of pipe about 6" long until i can get it to the exhaust shop.
Also swapped the pinouts to the rear o2 wires to have the longer wires for long tubes.
Initially i forgot to switch the ho2 low signal wires. fixed
no reading from o2 still.
Power and ground are correct as they have 12v and do heat up.
Although i have double checked the pins at the pcm I'm afraid i have crossed a wire and connected on of the old rear sensor wires instead of the front. How do i check the low/high signal wire is going to the correct pcm pin without yanking the harness out of the car?
TIA!

I would put some exhaust on it before trying to diagnose this problem. With just 6" of exhaust you're going to get faulty readings from the O2s . Fix that first to make sure you actually have a problem so you're not chasing your tail for no reason.
