What si this sensor for? Near starter motor

And these two? presume one near oil filter oil pressure sensor?

And there are two of these in top of inlet side of head, what are they for? One was removed when motor arrived

2. front knock sensor and oil pressure idiot light on dash
3. cam angle sensors

Chris is 100% right

1. Rear knock sensor
2. Front knock sensor (Near Oil filter) / Oil pressure sender
3. Cam angle sensor

Cheers

withg cam angle sensor, there is two of the same looking sensors, the one i have photoed and another one in middle of head, are they both cam sensors?

yes - 2jz and 1jz have 2 cam angle sensors (why? nobody knows)

The reason for two cam sensors is quite simple actually. The engine won't start until the ECU receives the first "home" signal from one of the cam sensors, and with a single sensor it could take up to two full revolutions of the engine before this happens (remember the cams spin at half engine speed). With two sensors offset at 180 degrees, this is reduced to a maximum of one engine revolution. The result is less cranking before the engine can start, which is a nice feature.
