Does anyone know where to find the speed sensor on an import 95wrx sti ra 555?

Gearbox.. you can see it just behind the downpipe iirc..

Cable come up out of it..

edit : however it is not really a sensor.. but cable driven.

There is a 30mph sensor too on the right hand drivers footwell wall, awkward to see and get too - It controls the power steering bias and puts the CEL light on if you go above 30 mph with the speedo disconnected.
Which one are you looking for mate??

The speedo is connected as the speedo is working, but whether it's accurate or not I am not sure.

The error that is coming up is 33, which points to the Vehicle Speed Sensor so I guess it's the cable that goes in the speedo and connects itself to the gearbox somehow.

I am wondering if this can become faulty.

I've just checked in the workshop manual for your car and the sensor is mounted in the engine bay on the firewall directly aft of the brake manifold adjacent to the drivers suspension turret. (I think it's just below the brake fluid resevoir)
The sensor sits at a slight angle to the horizontal and has a 3 pin connector plugged into it who's wires then go into a conduit.
Remove the plug (B91) from the speed sensor and :-
2 simple tests are to check for a minimum of 10 volts at the harness plug pin 3
The second is a resistance check of pin 2 to earth - Should be a max of 10 ohms.
Other checks involve use of an osciliscope to test output and continuity checks between the sensor and the ECU.
Hope that helps!!!
