Why does my speed senor contintue to malfunction even after getting a replacement? Now my check engine light comes on and I loose power while I'm driving. Please answer.
Are you sure it was the speed sensor.... speed sensor fail will also affect the abs.... now cam or crank sensor will put engine in limp mode.

remove the front 02sensor and drive the car like that, remove means complety take it apart from exaust, if problem goes away or gets so much better then your catalitic converter at the exaust is restricted and need a new one

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

THE PART YOU REQ IS CALLED A AIR INTAKE TEMPERATURE SENSOR HOPE THAT HELPS.

The engine speed signal code is generated from the crank sensor. The crank sensor is located on the back side of the engine block. See image.
Thanks Jay!

If the car is pinging you will set a knock sensor code.'
This comes from bad gas and running lean., You really need this professionally inspected to rule out the basics. I have seen alot of nissans with the knock sensor code stored but the light is still off.
Fill up the tank with high octane chevron and some techron injector cleaner and clear the light. If it stays off for a couple days then go get it inspected. Even if the code is stored it will still pass as long as the light is still off and the monitors have run.
