Hi,
This is new for me. Where do I begin to look? I saw the white connectors and they seem to be connected at each wheel area. I saw the single screww which holds(I think) the sensor at the wheel. I removed the screw but did not remove the plastic connector. It seemed to tight if it was a push in connection. What readings do I look for at the connectors? Voltage or resistance and the connector at the rear. Has anyone else had problems of this nature and does this light store a code also. A code key does not work on this model(1994).

Thanks .

Code key wont work properly on my '94 either.
The code will be stored in the PCM. A code reader goes for like $30.00 at pepboys or advanced.
I would get a scanner, make sure it has the rite plug, mines rectangular, before I started playing with the sensors.
Very fussy things.
Once You find the problem and correct it, reset the lite by disconnecting the battery for a minute. This will erase all the codes stored in the PCM.

Thanks cap man. I found the LF sensor OPEN. It should read about 1K ¥Ø ohms. Impossible to take out in one piece. I bought one of those scanners from PartsAmeica but on the back it had the exclusion for the 1994. I believe it will take care of the problem.
