3RZ-FE pinouts

[brett_celicacoupe]

had a few minutes while watching TV and a ECU spare so ive documented the pinouts.

this ecu was from a 1998' prado. with a manual W56 gearbox.

part number is TOYOTA: 89661-60370 & DENSO 175000-8801. M/T

the diagram is looking straight at the ECU

the plugs are 26PIN 16PIN 12PIN 22PIN.

the 22PIN plug connects to the dash loom and the other 3 go to the engine directly.

its interesting to note its a "M/T" ecu yet there is pin like PWR, 2, L, S1, S2, SL. unless the pins are there and the hardware isnt on the board.

i wonder why the ECU wants to know the car is in 4WD?

i think the ecu controls the 4wd light on dash

interesting to note that it's only got2 injector channels - so it's probably squirting in much the same way as the 4age or 4agze does

Also - what kind of idle control does it have? PWM valve?

Digging up this oldie.....

Just doing a 3rz-fe Pin out chart for a '99 4x4 and need help with some of the abbreviations in the ECU.

What is??

OXO (Could be OX0 'zero'.....0X2 is Oxygen Sensor...)
TFN
CASE ( Cam Angle Sensor?? What's the 'E' for?)
VAF
IMI ( Could be IM1)
IMO ( Could be IM0 'zero')

If G2 is Camshaft Position...What is Cam angle (as in CAS) Are they Different??

Forgive me if some of the answers here are common knowledge....but I wasn't raised in the era of Computers.

Do you still have the linked picture above by any chance?
I'm chasing down any wiring info I can find for a 3rz conversion I'll be doing soon.
