unplug those 10 pin connectors, expand the tabs a LITTLE using a very small phillips screw driver and press em back on.
Check that black wire to any of those sensors for ground.

The red wire on your meter goes to 12v+ battery terminal, the black end on the black wire, 12v scale

in fact wiggle them around and watch the reaction from the motor

I had a lot of these codes as well when I fried my ECM doing a auto to manual swap in mine. I hookedNDS 30to a 12vdc source of a manual ECM and fried it. Basically, I would check the voltage of 46 and 26 and see what you get.

But I would really look into the 67= neutral drive switch or circuit as it contols a lot of those circuits.

If its a 5 speed and its parked in gear when he pulled the codes it would pop up. Mine did .

i cut my exhaust off the other day..and damn, it had a thick black coat on the inside. and the cats were black. i was thinking that might've been causing the smoke..but it still smokes without the exhaust on. so its definetly the engine causing it.

This is a simple problem, you have codes, you have problem.

I am going with aode on this one.i agree and believe it is circuit 46 which is signal return on the pcm.. if you look at the wiring diagram, you see it goes from the pcm to the diagnostic self test connector. I would start on that circuit. Just disconect your pcm and check from pin 46 on that connector to the pin on the self test connector for resitance. if there is high resistance or it is out of limits.. there you have it.. you found your wiring problem.. if it doesnt have any resistance then idk what to tell you. lol
