i have done an ecu read on my classic terzo turbo and its come up 33 (vehicle speed sensor). The cars speedo had stopped working and the temp gauge was going a little crazy followed by the car going into limp mode which is all expected i believe when this sensor goes down.

Does anyone know the location of this sensor so i can get it changed. Bonus points for a diagram. Searched the forums but could not find anything.

Cheers

The speed sensor is in the back of the clock.
Its actually part of the speedo mechanism inside the clock, so I`d take your clock out and see whats what, the speedo cable is a little pita, but can be done.

 

cheers mate. I take it another solution is to get a new set of clocks if all else fails and that will rectify? Its a 1997 model. I heard there was a 2 and 3 pin so wasnt sure. Thanks for the reply

 

Just to check, you may have electronic clocks. So there is a sensor on the box that the cable on mine goes in, that the later ones have a sensor to convert it into electrical.

Worth looking as I`d assumed it was a cable operation, may be electric.

The sensor is next to the gear oil dipstick if you want to see if its come out.

 

Cheers fella. Yer its the white dials with all the circuitry on the back that feels like paper. Ill have a look when i get home in half hour. Thanks

 

Right, what am i looking at. I have the clocks in front of me. How do i get to the back of the speedo. It all looks a bit mad.

 

Leave the speedo in place, remove TMIC and look drivers side of the gearbox just to the rear of the gear box dipstick you will see a sensor screwed in. This is a right Shi**y job to do. Minimum you will need to take downpipe off. Sensor costs about £150 from www.importcarparts.co.uk.

One thing to note iirc is there are two variants of sensors, three wire and two wire.

Thanks for the heads up mate. Sounds ****ty. Not lookin forward to it now. Thanks mate

 

If you have access to a ramp, and remove the downpipe you may have a chance. Subaru do put thread lock on them aswell. When FB tuning did mine, we had the box on the floor and we still needed some heat on it.

the speedo drive (looks like a metal bananna) is screwed in gearbox and is only £30ish quid ile bet its that thats broke its listed on import car parts as bottom speedo drive

 

97/98 iirc went to electronic clocks

 

Cheers folks. Yer old man has an hydraulic ramp. Cheers for the advice folks. Ill have a muck about tomoz with it. Take it requires more than a bit of backbone an a spanner to get it out
