There is no afs on a cherokee, they run on a map sensor.
Yes, the computer will use the preset factory settings for the sensor. Performance will be impacted as well as fuel mileage.
Not very well.
Won't run run with out it.
engine will stall out and run very bad.
its either the throttle position sensor or the map sensor.
On a Prelude 91 Si, you can find the MAP sensor by looking at the black box which is mounted on the passenger side firewall. You should see vacuum lines that run to it.
The radiator fan sensor switch or the radiator fan motor are at fault (maybe even both). Wire the fan motor direct to see if it will run, if it does, replace the sensor switch. If the fan motor doesn't run, replace the fan motor before you buy a new sensor. If after replacing the fan motor, the fan still doesn't run, then replace the sensor.
yes the map sensor will keep the car from running.map stands for manifold air pressure and if the ecu cant get a reading it will not start and run.
Check the vacuum line on the map sensor for dry rot or other damage. If vacuum line on map sensor is in good condition the map sensor itself may be faulty and need replaced. The car will run with either a faulty map sensor or vacuum line. It would just run badly or stall. It might throw a code but not all the time. Also could be an ignition system problem or spark plugs needing replaced or the oxygen sensor may be faulty.
Not knowing what year, make and model you have, in most cases it runs to the ecm.
Yes, a 1993 Acura Legend (93) can start with a disconnected map sensor, but it may run poorly or have trouble idling. The engine management system relies on the map sensor to optimize air-fuel mixture for efficient combustion. If the sensor is disconnected, it can lead to rough running, increased emissions, and reduced fuel efficiency. However, the vehicle may still start and run in a limited capacity.
