Wrong scanner?? If a check engine light is on, there are codes.

Timing sensor? Check engine usually means a problem... Service means that scheduled service needs to be performed like oil change, or timing belt replacement.

I would Check your Catalytic Converter. What often happens is the catalyst that is in the Catalytic converter Heats up and Blows out into your Muffler.

This means It is not the sensor,but your converter and Muffler Need Replaced.I have just fixed two cars with this problem,and they had the same symptoms,Check engine Light.

What does the speed sensor on auto transmission do 1994 pathfinder?

If you mean what is the purpose of the speed sensor on an auto transmission do, then the answer would be it replaces the speedometer cable. Basically it picks up how many revolutions the wheels are making and sends that to the ecu (the computer) and the computer computes how fast you are traveling. All speed sensors do the same job, just some for different purposes. Some cars have speed sensors on all wheels which is used for abs braking, while some (Like this pathfinder) have one used just to tell how fast you are going.

What moves the mouse pointer?

In a ball mouse, the ball, which is moved by contact on a surface, has three directional roll sensors which transfer electrical signals to the computer which then moves the mouse pointer on the screen. In laser and optical mice, the roll sensors are replaced by lasers or infrared sensors, which detect which direction the mouse is moving. This is sent to the computer which moves the mouse pointer. Laser and optical mice are more accurate than ball mice, but don't work on reflective or transparen surfaces such as foil or glass, which is not a problem for ball mice.
