Hi Folks,

Hopefully in the finishing stages of a B20Vtec Swap. Everything that could've gone wrong, has so far, so if my problem is what I suspect, I won't be surprised.

I'm Not getting power at my TPS, I've verified at the ECU (Pins D11 and D20) There is no power.

It's a chipped P08, I haven't a clue to it's origins, it was in the car when I got it.

The car, for reference, is a 2000 civic si.

I poked around the rest of the D Block of pins on my P08 and saw no power elsewhere either.

Is there a fuse or relay that could cause behavior like this? Me and a friend who has helped me with the project are both stumped.

Car runs like **** of course, barely idles, doesn't respond to throttle input, dies out if I up the fpr.

Strange thing is, it was working a few days ago, although even then it seemed intermittent.

Even stranger, I drove this car with it's original B16A for many many years with this same ECU prior to doing this swap and never had an issue with it.

Any advice would be great, I'm not sure what else to try, going to start looking for a replacement ECU though in case it's the issue.

 

Because it was working and does not now I suspect a connection problem.
You would not see any voltage at D11 if there is none at D20.
You said, saw no power elsewhere either." D1 should be 12V+, [batt. voltage] through fuse, [hot at all times].
There are others most are 5V or less KOEO, so something is defiantly wrong.

I would start by finding out why you do not have 12V+ at D1, [blown or defective fuse] that should be the 7.5A back up fuse in the engine bay fuse box, it however, should not prevent engine from running properly but it is still a problem, it is a memory fuse for the ECU and the radio. 94
