Hello guys, First of all, let me introduce you mine z32:

I swaped VG30DET from Cima in my z32 6 years ago. It was non turbo block with turbo with z32 ecu and 1jz-gte injectors. I was 20 years old, it was ugly, but it worked. This summer engine died.
I bought 35 000 miles VG30DET from japan yahoo with its original ECU, MAF and harness (it's on the photo higher).
I almost finished with engine. It works stable, good starting. But there are some problems.
Well, The first questions I wanted to ask are:
1. AT doesn't shift gears.
I realised circuit just like in the manual. (I can work with it).
Self diagnosis of AT shows next errors: 1 and 9.
1. Revolution sensor circuit is short cutted or disconected. My question is what does this sensor do, how it works, what it shows to AT ECU?
2. Engine revolution signal curcuit is short cutted or disconected. My question is: Am I right that this is tachometer signal??? I made line from ECU pin 7 to tachometer and also line from ECU pin 7 to 24 pin of AT ECU. So this circuit is OKAY, but I don't understand why it show the 9th error code.
BTW - Tachometer is working! Speed sensor is working, Idle switch position circuit is okay (but shows 3V instead of 8-15V at 14 pin of AT ECU). Also, kick-down signal is okay, throttle sensor signal is okay, overdrive signal is okay, inhibitor signals are okay.
Do you have any ideas?? I appreciate any help
