Yes. But it won't run like it should
Rough on cold start
And you will probably be running rich
Haha
I'm in the same boat
Not very well.
Yes, you should always run your vehicle with its Knock sensor.
Depending on the vehicle the computer could default to a certain set point and still run. Some people have disconnected their MAP sensor completely and the car ran better than it hooked up, so they knew it was bad.
about $50
It may run a little bit rough or it may just run the same. Usually the check engine light will come on and it will indicate that you are running rich on left or right fuel bank. I am not a mechanic so my answer maybe incorrect. But this is what happened to my truck when the map sensor went bad.
There is no afs on a cherokee, they run on a map sensor.
MAP sensor going bad will cause that exact symptom, try unplugging the MAP sensor, if the vehicle will run with it unplugged then you know the MAP sensor is bad. My 88 Dodge Aries did the exact same thing.
If a MAP sensor has a catastrophic failure the computer should ignore the signal and assign a set value to that input. This will turn on the check engine light and put the vehicle in what is referred to as a "limp home mode". With that said I have seen a few isolated cases where the map sensor was melted and the 5 volt refferance signal was going straight to ground. In the cases I'm referencing the vehicle would start and run for a few seconds then stall. I have seen this condition twice on a 7.3L powerstroke diesel in E350's.
Get a code scanner for that vehicle and read the code. There is no way to figure out what's wrong without that information. It could be a MAP sensor, oxygen sensor, or any number of things that won't stop the engine but can make it run less efficiently. The computer will tell you what's wrong.
Get a tune-up ... change plugs, etc etc. The MAP sensor was probable only part of the problem.
Yes, you will, however the car will get terrible gas mileage and it will not run well. Without the MAP connected, the ECU will run on a fixed table, rather than the actual manifold air pressure.
Nope
