There is no afs on a cherokee, they run on a map sensor.
A 1998 Jeep Cherokee does not have a mass airflow sensor. It uses a manifold pressure sensor, MAP, which is on the rear of the intake manifold.
The TPS is not happy with the readings from the map sensor. More than Likely you have a bad sensor.
No, it uses a MAP sensor (manifold absolute pressure)
Map sensor voltage low.
it is in the intake manifold by the throttle body and the map sensor. it is a two wire sensor
It is located at the driver's fender side of the the throttle body.
That year did not have a MAP sensor.
5.2 v8 is located on the front side of the trottle body just above the intake.
Which motor does it have? If it is the 4.7L V8, it is on the front of the upper intake manifold, behind and off to the left of the alternator.
it checks to see if you are on the road or not. No, it actually tells the computer how much air is going in, allowing it to adjust the fuel air mixture. the jeep will not run very well at all without this sensor.
Check the MAP sensor. To see if this is the problem, assuming that the Jeep won't start but is turning over, unplug the MAP sensor and then plug it back in. If you can start it now, the MAP sensor needs to be replaced. The MAP sensor is located in the engine compartment, where the firewall meets the body at the top of the engine compartment, on the driver's side. Good luck.
If you have a 4.7 liter engine, the map sensor is located on the front of the intake manifold, behind the A/C compressor. Removing the upper air box may help in seeing the map sensor and also be out of your way for removal and install. Hope this helps.
The map sensor measures intake manifold vacuum . The signal is varied from high to low, this voltage signal change along with the throttle position sensor,vehicle speed sensor, o2 sensor, the computer uses the signals to vary injector pulse width.
You want to look on the intake manifold on the Jeep Wrangler.
It does not have a MAF, it uses a MAP sensor on the firewall above the intake.It does not have a MAF, it uses a MAP sensor on the firewall above the intake.
12 Battery voltage disconnected14 MAP sensor voltage too low15 No vehicle speed sensor signalAnswerSee the web site to the right.
The manifold absolute pressure sensor is installed in the intake manifold it is a simple installation thread in thread out.. but it is in various locations on the manifold depending on which engine you have The chilton or haynes manual will show you.
You might look at the o2 sensor or the temperature sender
Yo don't. It must be replaced if faulty.
soundsl Ike the TPS on the throttle body is bad or the MAP sensor is bad. probably tps.
P0108 is map sensor volts too high. The map sensor could be bad, or the wiring could be broken. The map sensor bolts to the rear of the intake on the 4cyl.
It is located on the drivers side of the throttle body
the timing on all the 4.0l (242 cid) engines are set and only adjustable through the computer sensors (map sensor). It is not physically adjustable. So there is no procedure for you to adjust it.
