    The code that I got on my jeep liberty diesel was P0101. It is a diesel so I am not sure that the information that you gave me is any good. Maybe there is some miscomuncation?

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.......

DTC P0101
Circuit Description
The mass air flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. The powertrain control module (PCM) uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. A small quantity of air entering the engine indicates a deceleration or idle condition. A large quantity of air entering the engine indicates an acceleration or high load condition. The MAF sensor has the following circuits:
• An ignition 1 voltage circuit
• A ground circuit
• A signal circuit
The PCM applies a voltage to the sensor on the signal circuit. The sensor uses the voltage to produce a frequency based on the inlet air flow through the sensor bore. The frequency varies within a range of near 2,000 Hertz at idle to near 10,000 Hertz at maximum engine load. The PCM uses the following sensor inputs to calculate a predicted MAF value:
• The barometric pressure (BARO) at key ON
• The manifold absolute pressure (MAP) sensor
• The intake air temperature (IAT) sensor
• The engine coolant temperature (ECT) sensor
• The throttle position (TP) sensor
• The engine speed (RPM)
The PCM compares the actual MAF sensor frequency signal to the predicted MAF value. This comparison will determine if the signal is stuck based on a lack of variation, or is too low or too high for a given operating condition. If the PCM detects the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value DTC P0101 sets.

Important:: The Altitude vs. Barometric Pressure table indicates a pressure range for a given altitude under normal weather conditions. Weather conditions consisting of very low or very high pressure and/or temperature may cause a reading to be slightly out of range.
Turn ON the ignition, with the engine OFF.
Observe the MAP Sensor kPa parameter with a scan tool.
The manifold absolute pressure (MAP) sensor pressure should be within the specified range for your altitude. Refer to Altitude Versus Barometric Pressure .
Is the MAP sensor pressure within the specified range as indicated on the Altitude vs Barometric Pressure table?

Replaced MAF sensor, the MAP sensor, Idle Control Sensor and the throttle position sensor, now I'm getting P0101, P0102 and P0135 codes


P0101
Mass or Volume Air Flow Circuit Range/Performance Problem
P0102
Mass or Volume Air Flow Circuit Low Input
P0135
O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1

Your O2 sensor needs replacing...do this then disconnect negative battery ground, wait 10 minutes and reconnect. If all cleared, use a scan tool and clear properly, these are relatively cheap or take it to a shop.

The belt tensioner is defective. It automatically keeps the belt at the proper tension. P0101 - MAF sensor (mass air flow sensor) or circuit problem. P0107 - MAP sensor (manifold absolute pressure sensor) signal is low.

Jeep 2005 Liberty CRD diesel oil light and beep


I've never seen an oil pressure sensor that costs $750...Likely something else was done to justify that cost. If the light has not come on since the repair, I'd assume that problem has been corrected. If not, have the thing checked out again. If they charged you to repair it, then it should be fixed or, it's their problem!!! You should not be afraid to drive your vehicle. It's a machine, therefore it can and will break sometimes as do all cars. But being afraid to use it is not a solution.

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.
