Speed sensor

[danthomas11]

So what is the typical situation for a speed sensor failing..... Does the transmission switch when its not saposed to?

What is this speed sensor that you are speaking of?

 

[danthomas11]

on the transmission

Speed cable maybe?

if your speedometer isnt working, I'd probably lean more towards the No 2 Speed Sensor behind the dash cluster.

 

[danthomas11]

no my speedometer is working.

 

[starscream5000]

How do you know your speed sensor is bad?

 

[danthomas11]

the transmission isnt shifting when its sapossed to

 

[starscream5000]

Press in your clutch and shift the damn thing!

 

[danthomas11]

Then edit you profile numb nuts . How do you expect us to help if you are leading us to believe you have something that you don't?

 

[danthomas11]

oh shit, lol didnt notice it was wrong.

The speedometer is driven by a cable, it isn't electronic.

When he was saying speed senor, I was wondering how it tore up as I've never heard on the speed sensor in the cluster messing up. I think he's a little confused. Your speedo is working. Your problem lies elswhere. Check you transmission codes.

I believe the A/T cars have 2 speed sensors, 1 in the speedometer and one in the ABS sensor.

If your speedometer is working, chances are it's the rear ABS sensor on the tranny.

Take a read through the TSRM, it'll probably help, as it has diagnostics in there.

Save this website in your favorites, it is now your bible : http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=EC&Page=16

Heres the page for your diagnosis for the speed sensors as I stated above.

The #2 speed sensor is on the tranny...drivers side.

The #1 Speed Sensor is in the speedo itself.

Question,

If the ABS is not hooked up, will/should the car throw a code for the speed sensor as well as the ABS light?

If the answer is yes, it would answer another question I've been wondering about.
