If the sensor is the problem then the answer is yes. But unless you know how to diagnose the problem you are just throwing parts at the problem and may spend lots of money and still not have it repaire. I suggest you have this repaired by a professional who knows what they are doing.
Not sure what out put sensor you speak of but, in most cases after you replace the correct faulty part, the ecm will shut off the check engine light and eventually clear the code(s) after so many ignition cycles.
Try cleaning or replacing the Idle air control sensor.
If the ejector pumps keeps running, it may have a faulty shut-off sensor. The best thing to do is to try replacing the sensor and see if that corrects the problem.
check your oil pressure sensor, it is an easy fix.
An oil level sensor will shut down the Ford Expedition. If the oil level sensor senses that the vehicle is low on oil, a light will alert you to the fact before the vehicle shuts down.
Perhaps the collision sensor that shuts the fuel off on impact is set too sensitive

If the cam sensor was the cause, the light will eventually shut off. It may take a couple of weeks.

Tampering or replacing ignition that does not match up with your key will cause your security to shut your car down.
If the ABS light is on , a malfunction has been detected . It could be a fuse , a sensor , or some other problem
Probably a sensor or a chip. Have the dealer find out if there is actually a problem with the airbag. If not, either have the sensor fixed, or use my method--black duct tape over the light. Tacky, but works with a budget.
