Please identify this Speed Sensor

[Sargent]

I'm stumped trying to identify the speed sensor on my FJ80. This one is broken and I need to replace it but can't find an easy replacement now that Downey is gone. I need suggestions on where to find/make a replacement. It would go a long way if I could identify this one...

Here are the essentials on the truck.

• 1991-Stock A440 Transmission
• Chevy 5.7 Vortec conversion (VSS goes right to chevy computer)
• Chevy requires a 40 pulse speed sensor
• This sensor works about half on the time then throws VSS error.

Here are the pics:

Here is the part, I purchased mine at:
Toyota Parts : 1stToyotaParts.com
This is the Toyota original part, and is 40 pulsesI think it was about $75

could this be why my cruise control doesnt work anymore?

Bench test from the FSM:

Connect terminal 1 to the positive side of the battery. Connect terminal 3 to the negative side of the battery. Check that there is continuity four times per revolution of the shaft between terminal 2 and the negative side of the battery

The black is ground...negative
The red is positive
The yellow is sensor out....should be 4 pulses per revolution.

The output is a square wave pulse, and not a sine wave.

Yes, but there's an easy/fun diagnostics section (similar to pulling CEL codes) in the FSM that will pinpoint the problem for you so you don't have to guess.

Now were talking!! So is this the factory sensor? If so I was under the assumption that it was not 40 pulse compatible...

Thanks for posting this definitely solves the riddle...
