MAP/DARO circuit high input
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

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.

12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle. Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.

I would check to be sure that the timing chain hasn't jumped at all ..

IAT Sensor Circuit High Input
Print this code data
Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
Check with ignition on or engine running; battery voltage more than 10v; The PCM detected the IAT Sensor input was over 4.90v (exc. Dakota, Durango, Ram) or 4.98v (Dakota, Durango, Ram) for 3 seconds.
Possible Causes:
SOURCE: location of tps and map sensor on a 02 jeep grand cherokee 4.7l
Both are attached to the throttle body. Tps is on the other end of the throttle plate shaft opposite the linkage, MAP is on the side...has small vacuum hose underneath and is flat, about 3" long. The other item on the TB is the idle air motor, next to tps.
SOURCE: What does codes p1757 an p1762 on 2001 grand
The codes are for governor pressure(transmission) either too low or high. First thing to do is clean all the electrical connections on the trans plug drivers side on top
above pan behind shift linkage And another plug from trans by fire wall follow
the wires back. Try that first before spending a lot of money on the trans governor pressure solenoids. You will need a scanner to clear codes to see if it fixed the issue. I hope this helps
