I was told that the MAP sensor was bad in my car. I looked up online how to replace the sensor, it seems fairly easy. My only problem is I have NO CLUE where it is?! It would be great if someone had a diagram or very good instructions on where to locate this!
Alright I think I might have the same problem. I am trying to add the photos of where the sensor is but I am not sure it is going to work. If the pics do not come through, then just look to the left of the transmission dip stick and I believe it is the on the back side of the engine. It has a red clip that is holding on the wires to the sensor and it is the left one of the two clips back there. Also before replacing the sensor check out the link below. Another person was having the same problem and fixed it without replacing the sensor. The guy helping him said that if you have bad spark plugs or wires it could trip the MAP sensor trouble code. Hope this helps.

The MAP sensor communicates the barometric pressure inside the intake manifold to the ecm.
This code can indicate either a fault in the MAP (manifold absolute
pressure) sensor, or a possible vacuum leak, either from a hose or the
I would NOT drive your car until this is fixed, especially if its
running bad. Erroneous information from the sensor can cause bad
mileage, misfires, rich or lean running, which can cause catalytic
converter or valve damage if left untreated.
they are easy to replace, a new one should run less than $125, and they are fairly easy to find used in the local junkyard.
Please tell us your NOT replacing a cam sensor because someone told you to get a code read at some auto parts store. This is like the flu spreading on this site. Codes DO NOT always mean a sensor is bad. Test it before you throw parts at it.
I posted this response to a similar situation. I am dealing with it now and have narrowed it down to these issues...
The O2 sensor, the speed sensor or the MAP sensor may be one of the problems. The MAP sensor measure the air pressure in the manifold. It is commonly mounted on the fender and is low in cost and easy to replace. To test it if your if your car won't start, unplug the electrical connection from the MAP sensor. If it starts, then you know to replace the MAP sensor. The Hall Effect sensor can fail and not set an error code. This is an inespensive part that sits underneath the rotor in the distributor cap on cars without distributorless ignition. This only applies to cars made after 1996. Also check the fuel injectors and fuel filter.
If you have a burglar alarm, make sure that it is not causing the problem. It often times can cause the stalling issue.
For a 2.7 liter six cylinder engine, the camshaft position sensor is located in the front or on the right side of the front engine head. Be sure the engine is cool before you start to remove it. It's fairly easy to change, just in an awkward spot to get to. You can see the connector on the front of the head just right under the top radiator hose. The sensor is held in with a 13mm bolt that has a wiring support tab attached to the top. Remove the wire support tab and then remove the bolt. After the bolt is out, just pull the sensor out with you fingers. A new sensor from the dealer will run around $55.00. Good luck and hope this helps. keep me posted, be glad to help.
I had this problem with my 99 Durango and went to AutoBeef.com to discover this was a major problem with 98 & 99 Durangos. The fix was easy -- PCM "brain" was exchanged with a refurbished PCM "brain" from an online PCM company in Florida. You can google as I can't remember name of company. I called them and they said - Yep this is the fix -- the guys told me 3 screws all I had gone to several mechanics and dealers -- none could figure it out. I was so grateful that someone gave me the clue I needed.
If your car has a MAF (Mass Air Flow) sensor, it would be located in the air delivery tube that runs from the air filter box to the throttle plate assembly on the intake manifold. It will have a wiring connector going to it, also. The MAF does exactly what it is called: It "senses" the volume, or "mass" of the air-flow; thusly it needs to be in the intake air tube. If you do NOT have such a device in the air-tube, you have a MAP sensor, (Manifold Absolute Pressure); this is another way of measuring the same air volume, albeit older technology. You will commonly find this device on the firewall, with a vacuum line running to the intake manifold.
I hope that this sheds some light on your question.
A manifold absolute pressure sensor (MAP) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). This is necessary to calculate air density and determine the engine's air mass flow rate, which in turn is used to calculate the appropriate fuel flow. (See stoichiometry.)
An engine control system that uses manifold absolute pressure to calculate air mass uses the speed-density method. Engine speed (RPM) and air temperature are also necessary to complete the speed-density calculation. Not all fuel-injected engines use a MAP sensor to infer mass air flow; some use a MAF (mass air flow) sensor. Several makes use the MAP sensor in OBD II applications to test the EGR valve for functionality. Most notably General Motors uses this approach.
