SOURCE: 2005 jeep liberty diesel code # p0101 map- sensor out of range what is map

The MAP sensor (MANIFOLD ABSOLUTE PRESSURE) changes voltage or frequency as intake manifold pressure changes (air flow increases or decreases). The engine's computer uses the reading to advance or ****** engine timing. On older, non-fuel injected engines the vacuum advance on the distributor did basically the same thing.
The MAP sensor also works with other sensors on the Jeep engine, specifically the Throttle Position Sensor (on the throttle body) and Crank Position Sensor (on the transmission bell housing) to control other fuel flow and ignition timing functions.
If you're having problems with the MAP sensor, or are getting a Check Engine light and code for the MAP sensor keep in mind that other problems may cause that error code.
Bad vacuum hoses, vacuum leaks, bad EGR valves, intake manifold leaks, clogged air filter can all affect the MAP. sensor. To know for sure all the other sensors should be checked for correct voltage and perimeters
Also, if you have done any mods to the engine, especially intake, exhaust and ignition mods you may get an error code for the MAP or incorrect reading and a resulting loss in power or increased fuel usage.
The map sensor is easy to change with a couple screws off the Throttle body.. The part the air inters (the air breather). Buy one from the auto parts store if your sure that is the problem and just replace it..There is no adjustments to it...

It really sounds to me that you have a small vacuum leak in a line somewhere.You can try spraying the motor vacuum lines with soapy water with the vehicle running to find a leak. Also listen and feel under the dash for leaks and hissing sounds.
Hope this helps.......

SOURCE: i have a 2006 jeep liberty and three lights are staying lit and

You need to take the jeep to a dealer or a good mechanic who can retreive the codes out of the computer. You may have a module problem but I will not guess without knowing the codes.

Need a wiring diagram for map sensor in 2006 Jeep Liberty 4x4 3.7L

Go to autozone and ask for the wiring diagram. They will print one for you for free. If you dont have an autozone near you try another parts store. If you purchase a haines of chiltons manual ($25 in a retail store or $18 on amazon), it will have a detailed wiring diagram of the MAP sensor.

Good Luck!

I need to replace the map sensor in my 06 jeep liberty diesel...i was wondering if you know the location of the map sensor...i think it is location inside the airbox

The Manifold Absolute Pressure sensor is located on top of the cylinder head, right side, about 2/3 of the way back. there is one screw holding it in. You will need to take off the plastic engine cover off to access it. The sensor in the airbox is the MAF sensor.
