Yea, I'm going to solder it. So far this is what I got. The wire with the ecu pin has continuity. The sensor port on the engine to ground has continuity, the sensor plug to ground has continuity. So the equation means its from the plug to the ecu I'm assuming.

Yea, ever possible connection has good continuity. It's probably just a poor connection. And I have no clue whats up with my AIT.

I just dunno, I tested the continuity between the ecu pin and the selinoid plug and it says it has continuity. It just seems like my ECU isn't reseting or something.

If my ecu is reset, it shouldn't get code 21 untill it hits the vtec rmp right? Because I took the fuse out for like 3 minutes and put it back in and it picked up teh code right away without turning the engine over.

That is right. Did you leave the jumper in the service connector?

Yes on accident. Ill go pull out the spade I used to jump it.

Ok, I have the fuse out, let it sit for like 5 minutes, then took out the service jumper spade, should i just let it sit some more or do I need to repeat the process?

That may be your problem then....

Just pull the neg terminal of the battery and reconnect it and it should do the same thing as removing the fuse, but faster.

Hmmm. No matter what it picks up the code 21 right away. It's not the wire connections. Prolly not the sensor because it's getting continuity. Damn ECU >_<
