The book says TDC Sensor Intermittent Interruption. What the hell is a TDC Sensor? Where do I find it?

Tried this twice:
Here's the story, car drives fine as long as I stay below 6000rpms (I drove about 200 miles without Vtecing). No hiccups, pulls, feels strong. But as soon as I gas it, the car will backfire, and I get the CEL. Then I can not go above 3000rpms. Pulled the code and it is P1361. What should I be looking for? Any help would be appreciated. I changed the plugs from IK22 to Honda Spec after the first CEL, just to be safe. So I have clean fresh plugs in there right now.

 

Sounds like it may be a loose connection on one of those two sensors at the back of the valve cover. Had it off lately?

 

Chris or anybody who can get me a picture. Would you mind pointing out/circling which two sensors? I have no clue what I should be looking for. I can't remember the last time I had the valve cover off, it had to have been months ago when I swapped out the head.

 

they are both on the back of the red valve cover. one is in the very back, and one is in the back but to the driver side. each has a connector that goes into them. and when you pull them out they have a roud metal cylinder on them.

if my cable modem doesn't go down, here is a picture of them. refer to parts 3 and 6.

 

Squeezer, thank you very much. I'll go check the connections.

 

So can somebody explain to me what the TDC sensor does exactly? I am wondering if this is a precursor to a bigger problem?

TDC = Top Dead Center, so does that mean I might have a problem with my pistons?

 

I think it will just be a problem with the sensor(s), not the pistons. Has the valve cover been removed recently? It seems that they could easily be damaged during the removal or installation of the cover, since they get so hung up on the firewall lip and cams.

 

Or I guess it could be a loose, broken, or bent camshaft plate (part #22 above). The TDC sensors detect the bumps as they spin.
