Question about 2002 Nissan Sentra
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.

SOURCE: 1996 Nissan 200SX Speed Sensor
It is possible that this code can be caused by the speedometer head itself. The signal from the speed sensor is processed in the speedometer and then sent to the ECM. Check the two screws on the back of the speedometer to see if they are loose. If so retighten and drive to see if the check engine light comes back on. If they are tight, replace the speedometer assembly( I think you gave to purchase the entire meter assembly). If the light still comes on, which is unlikely, you will need to check the wire going to the ECM.

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.
