    to change my previous comment a little they are not exactly the same but they do the same thing essentially.

MAP is Manifold Absolute Pressure. It is not the same as barometric pressure. There are YouTube videos on-line to show you where and how to change them.

SOURCE: 1999 Nissan Altima MAP sensor location

The MAP sensor is located on the driver's side of the engine compartment next to the air filter housing and shock tower.
It is a small plastic component with one vacuum hose coming off of it and an electrical connector that has two wires. It might be advantageous to write in and let me and/or other techs know what the symptoms are prior to replacing the sensor. Sometimes just replacing the part is a waste of money. The fact that the code has indicated the problem is the MAP sensor, doesn't mean it is bad. As an example, check to see if the Vacuum hose is secure and not disconnected or split at either end.
Good luck.

Your map sensor is mounted on the throttle body. This is what you're looking for.a2184d5.jpg

I need a diagram or location of the vacuum hoses on a 2007 Chevrolet Impala LT 3.5

Hears the deal Chevy really dosn't use vacuum for engine control it is more important for the AT transmission shifting .
You have main lines 1 goes to the vacuum booster control unit for the power brakes another goes to the PCV valve and depending on what you have for small lines going to vacuum reservoirs
I would look at the MAP sensor Manifold absolute pressure .
All vacuum comes off the intake manifold its the draw of air the engine needs to run .If the Map is bad you will have A LOT of of problems with how that engine runs ,It plugs in to the intake manifold 3 wire about 75 dollars maybe slightly less its a good place to start .

Where is located barometric pressure sensor in gdi 4g93 mitsubishi

Tell me what code you are getting .
A barometric pressure sensor dose not work on its own .
You have the mass air flow sensor this is the first air sensor coming into the vehicle then you have an air temp sensor then what is called ECT engine coolant temp sensor .
The problem to me sounds like the MAP sensor manifold absolute pressure .You loss this the vehicle is not going to run to good.
If it wore the mass air flow it would cost the most the map is far less in price still not cheap the barometric sensor it likely a symptom of the real problem .
Check the gas flow in side the engine like EGR and EVAP systems to a vacuum thing .

I have a 2005 chevy impala and the codes that came back with the engine light on are p0107 and p1107 Can you help me? It is driving sluggish. It doesnt accelerate very well and it only has 66000 miles...

P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input the other one is a MAP sensor problem, usually associated with someone adding or spraying some sort of cleaner either in the tank or into the throttle body to clean that out,, this is never a good idea, you can try this,, but if the MAP sensor is clogged up with residue,, it probably won't work
turn your key to the on position, wait 2 seconds turn it off wait 3 seconds turn your key to the on position, wait 2 seconds turn it off wait 3 seconds turn your key to the on position, wait 2 seconds turn it off wait 3 seconds on most cars that will reset the lean mixture

Po108 service code

OBD II Fault Code
  • OBD II P0108
Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold air pressure into a voltage that is high when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.
  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur
Common Problems That Trigger the P0108 Code
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections
Common Misdiagnoses
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

Component locator - cannot find the MAP sensor

TESTING-MAP- A vacuum line runs from the sensor mounted high to the intake manifold so it can measure the vacuum in the intake manifold. NOTE: Unusually high or low barometric pressures can generate a false DTC for the MAP sensor. If no driveability symptoms accompany the MAP code, do not replace it.
  1. Connect a MAP/BARO tester to the sensor connector and sensor harness connector. With ignition ON and engine OFF, use DVOM to measure voltage across tester terminals. If the tester's 4-6V indicator is ON, the reference voltage input to the sensor is okay. NOTE: The green light on the tester indicates that the VREF circuit is okay, 4-6 volts. A red light or no light indicates the VREF is either too low or too high.
  2. Measure the reference signal of the MAP sensor. If the DVOM voltage reading is as indicated in the table, the sensor is okay.
    1. Turn the ignition OFF.
    2. Disconnect the vacuum hose from the MAP sensor and connect a vacuum pump in its place.
    3. Apply 18 in. Hg of vacuum to the MAP sensor.
    4. If the MAP sensor holds vacuum, it is okay. If the MAP sensor does not hold vacuum, it must be replaced. Fig. 1: Manifold Absolute Pressure Sensor 84174020.gif
