Power Steering Not working Speedometer not working Its probley the Speed Sensor!

[bigdog76]

I tracked this usefull information down online for all of us that are having this problem.My power steering is not working and my speedometer is dead at the same time. A master mechanic at the Infinity dealer said its the speed sensor and many people on this site agree. Read the below and see if this information makes since about what the speed sensor does and how to check/ or replace it. I bought mine thru infinity Scottsdale for $134 its on order/

I have replaced at least 3 of them and have never had any of these cars store a code 15. In at least one code list I saw, the 15 says "no speed-distance sensor signal," in which case the typical failure mode will likely NEVER set a code, since they don't usually stop sending a signal.

This sensor comes out with the removal of a 10mm bolt and by disconnecting a wire (and by removing the speedometer cable and maybe by separating the two halves, on older units). Takes about 5 minutes (more if you have to find it first).

I did the most recent of these on Saturday on my mom's '86 Reliant 2.5/A413. She had the same 'stall as you come to a stop' symptom, as well as the transaxle acting (in my mom's words) 'as if the transmission was 'slipping' on the highway. This is the other common symptom of a bad speed/distance sensor. The sensor gives the computer the speed info, and the computer uses it to lock and unlock the torque converter. When the sensor is bad, the transmission will often go into and out of lock as the erratic sensor 'says' the car is above or below the lockup speed (about 38 mph).

...

Park on a flat and level surface. On a TBI car, pull the air intake hose off the airbox and move it out of the way. Then reach down behind and under the airbox, following the wires that go down that way. In the end of the transaxle just behind the bellhousing, you'll find the speed sensor at the end of the wire. (This is easier to do than describe.) Disconnect the connector by pulling the tab out from the connector body and pull the connector out.

Feel around the connector for the bolt. This is a 10mm bolt. Remove the bolt, then gently pull up and/or twist the speed sensor and it will pop out. If the transaxle is not overfull and you parked on a flat surface, no transmission fluid will leak out.

The speedometer pinion will be snapped onto the end of the sensor. Remove it and reattach it to the new sensor. Then reinstall the sensor, twisting as necessary to mesh the speedometer pinion with the drive gear. Put the bolt in and tighten (doesn't have to be really tight), reconnect the wire, put the air hose back in place and go wash up.

If you're slow and it is the first time, it will take a half-hour. I can do this in less than 10 minutes, having done several now.

BTW, you can test the sensor with an ohmmeter. Remove the sensor as above, and connect the ohmmeter to the two terminals on the sensor. Rotate it. You should get 8 pulses of zero resistance, and infinite resistance in between. Anything else, and the sensor is bad. You may want to check this, and look for chafed wires, etc. before replacing it to be sure of the cause of the code 15.

Well i replaced the speed sensor and that was not itNext will be the clusterI can get a used one for $90 bucks

Anyone have any advise what this dam problem is???
