1999 - 2002 Nissan Quest

I have a 2002 Quest. My service engine lights cut on and off some days. While I'm driving I notice the spedometer stops working. Somes day's it works and some days it doesn't. Seems it usually works when the wheather is warmer. I also notice the over drive light blinks several times when I start the engine. Does anyone have an idea of what's going on?

you need to replace the speed sensor drivers side corner of trans if you look from the top you can see it .run it up on ramps climb under its right there close to outside corner.I got mine from autozone about 80.00 they can print out the location for you, start to finish about 20.mins good luck Bob

the only thing is be careful with the retainer clip for the gear (you must remove from old and put on the new sensor )and oil the o ring on new sensor before you install :)
