Speedometer problem

[tuco]

I have a 1994 toyota pick up manuel trans. My speedometer was working intermittently. And now it is not working at all. Changed the speedometer sensor along with the nylon gear that fits inside it. Still no luck. The repair book also talks about a ECU what is this? And could this be the problem? Need some help please. I'm already in this with $150 worth of parts.

I'll look in my service manual tomorrow and see what it says about possible problems. The ECU is the electronic control unit, not a good thing to fail.

My son had a speedmeter problem and bought a cheap GPS to use as a speedmeter since repair was really expensive. I have a GPS's now in two cars and love the accuracy as compared to speedmeter plus get driving directions on one of them. Only disadvantage is thugs wanting to steal them!

I get back to you tomorrow evening if nobody else replys.

regards.

I have a 1992 pickup 2wd. My service manual indicates to inspect the speed sensor and to check if there is continuity between terminals a and b four times par each revolution of the speedmeter shaft. If operation is not as specified, replace the speedometer.

You should be able to just hook up a ohmmeter and see if you have continuity, (0 ohms) fours times each revolution - to my understanding. I have never troubleshoot a speed sensor before myself.

Try just searching the internet for Toyota service manual with your year, maybe you can find a site with your year vehicle. Sorry, got to go.
