To correct this problem u will most likely need to replace the Atmospheric pressure sensor, this is a fairly common problem. below is a link to the diagnostic testing that should be done before spending the $200 for the part.

What does code PO108 mean on a 2001 Grand Cherokee


wow , you actually tried to look it up, a 1st time here.

the MAP is a baro sensor used to calculate fuel injection RATES.

if you have gross air leaks to the system the engine IDLE screams.

is it?

108 means the voltage is too high.

usually its unplugged, or bad sensor.

otential causes of a P0108 code: Bad MAP sensor Leak in vacuum supply line to MAP sensor Engine vacuum leak Short on signal wire to PCM Short on reference voltage wire from PCM Open in ground circuit to MAP Worn engine causing low vacuum



Bad MAP sensor Leak in vacuum supply line to MAP sensor Engine vacuum leak Short on signal wire to PCM Short on reference voltage wire from PCM Open in ground circuit to MAP Worn engine causing low vacuum

and last. but before ECU.

low engine compression, is 1 more, causes , many



what i do is reseat the MAP sensor

i then make sure he vacuum port is not clogged. (both sides)

i then measure the output , keyon, and idle and gunning throttle.

any Voltmeter works here,

key on is 5v or near.

idle 1.8v

gun engine as the RPMs fall like a rock the volts tries to hit 0.5vdc.

very very easy to find with a voltmeter

if the meter agrees with vacuum gage, then the MAP is ok

and you have air leaks or low vacuum for (VAST reasons)

ask.

Code po 107 comes up on my 98 chevy pu map/baro circuit low input already change the map sensor and find that there is no power in the plugwhat do I change now?


You may need a wiring diagram to make sure, but I think the gray wire is reference voltage and it also powers the throttle position sensor. The sensors get power from the engine computer.

2004 mercury grand marque check engine light on code is p0108 says map sensor or vacum leak but does not have leaks.this car does not have map sensor what else needs to be replaced


PO 108 --- Baro/Map Sensor High Voltage Detected

Yes it does

It is integrated into one unit in the ESM EGR assembly
(possibly)

I have no experience with that,so if you find only an egr valve
& no other sensor with vacuum hoses & wires going to it,replace
the egr valve.

Getting the feeling you missed it

Work the web sites. Put in your motor & EMS Module for egr
& see what comes up

I have a code P0108 Map/Baro Circuit High Input does that mean that my map sencer is nogood


the map/baro circuit could have an internal short suppling incorrect voltage to the wrong circuit.you need to check the voltages,ground,and return voltage at the sensor plug with it connected to the sensor with the key engine off and the car running to see if the sensor is getting the proper voltage and has a good ground,also check the plug itself as it could be the problem
