    Manifold Absolute Pressure Sensor



    See Figures 1, 2 and 3

    Fig. Fig. 3: MAP sensor location-3.3L and 3.8L engines
    The PCM supplies 5 volts of direct current to the Manifold Absolute Pressure (MAP) sensor. The MAP sensor then converts the intake manifold pressure into voltage. The PCM monitors the MAP sensor output voltage. As vacuum increases, the MAP sensor voltage decreases proportionately. Also, as vacuum decreases, the MAP sensor voltage increases proportionally.
    With the ignition key ON , before the engine is started, the PCM determines atmospheric air pressure from the MAP sensor voltage. While the engine operates, the PCM figures out intake manifold pressure from the MAP sensor voltage. Based on the MAP sensor voltage and inputs from other sensors, the PCM adjusts spark advance and the air/fuel ratio. The MAP sensor is mounted to the intake manifold, near the throttle body inlet to the manifold. The sensor connects electrically to the PCM.


    See Figures 4, 5, 6 and 7

    Fig. Fig. 7: Using a digital volt-ohmmeter, test the MAP sensor voltage-3.0L engine shown

    1. Test the MAP sensor output voltage at the sensor connector between terminals B and C (2.4L, 3.3L and 3.8L engines), or A nd B (3.0L engine).
    2. With the ignition switch ON and the engine not running, the output voltage should be 4-5 volts. The voltage should fall to 1.5-2.1 volts with a hot, neutral idle speed condition. If OK, go to the next step. If not OK, go to Step 5.
    3. Test the PCM terminal 36 for the same voltage described in the previous step to make sure the wire harness is OK. Repair as necessary.
    4. Test the MAP sensor ground circuit at the sensor connector terminal A (2.4L, 3.3L and 3.8L engines) or C (3.0L engine) and PCM terminal 43. If OK, go to the next step. If not OK, repair as necessary.
    5. Test the MAP sensor supply voltage between the sensor connector terminals A and B (2.4L, 3.3L and 3.8L engines) r A and C (3.0L engine) with the ignition key in the ON position. The voltage should be about 4.5-5.5 volts.
    6. There should also be 4.5-5.5 volts at terminal 61 of the PCM. If OK, replace the MAP sensor.
    7. If not, repair or replace the wire harness as required.


    See Figures 1, 2, 3 and 4
    The MAP sensor is mounted on the intake manifold near the throttle body inlet to the manifold.

    1. Disconnect the negative battery cable.
    2. On the 3.0L engine only, disconnect the vacuum hose from the MAP sensor.
    3. Detach the electrical connector from the MAP sensor.
    4. Unfasten the mounting screws, then remove the MAP sensor from the vehicle.

    I have this eobd code problem p0105 in my elantra, where those sensors?

    P0105 - Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
    The MAP (Manifold Absolute Pressure) sensor is part of the fuel management system. It reacts to changes in engine manifold pressure. The PCM (Powertrain Control Module) monitors the MAP sensor continually to properly run the engine. Changes in engine load require changes in the amount of fuel injected, and timing of the ignition system, etc. An engine under load has more manifold pressure(or less vacuum) than an engine that is coasting. As the load changes, the MAP sensor voltage signal to the PCM changes accordingly. To check the MAP sensor operation, though, the PCM watches other sensors to verify that the MAP sensor is working properly.

    For example, the PCM compares the TPS (Throttle Position Sensor) signal to the MAP signal to verify the MAP signal isn't "sticking". If the PCM doesn't see a MAP sensor change immediately follow a change in the throttle pedal sensor, it knows there is a problem with the MAP sensor and sets P0105. Or, if the PCM notices that the TPS indicates the engine is under load, but the MAP signal indicates that the engine is "coasting" it, again, knows there is a problem with the MAP sensor or TPS and sets P0105.

    Symptoms of a P0105 check engine light code may include:
    * Poor running engine
    * Engine runs rich
    * Engine won't idle
    * Engine backfires through tailpipe
    * Engine misfire under load or at idle
    * MIL (Malfunction Indicator Lamp) illumination
    * In some extreme cases there may be no symptoms other than MIL illumination

    Causes: A P0105 DTC could be caused by:
    * MAP sensor vacuum hose disconnected or plugged
    * Bad MAP sensor
    * Bad TPS
    * Damaged or problematic MAP sensor connector
    * Damaged or problematic TPS connector
    * Damaged wiring
    * Short to reference voltage on signal circuit of MAP sensor
    * Loss of ground to MAP sensor or TPS
    * Open on signal circuit of MAP sensor
    * Bad PCM

    Possible Solutions:
    Using a scanner or code reader, turn the ignition on and engine OFF; what does the MAP sensor voltage read? It should be about 4 Volts for sea level. If you are at a higher altitude, it should decrease about half a volt or so for each 1,000 ft. of altitude (this will vary from model to model) Or if you have a separate MAF (Mass air flow) sensor on your vehicle, they are usually equipped with a Barometric pressure reading. If so, the Baro reading should match the MAP reading (they both measure ambient air pressure). If they're roughly equal, then, check for Freeze Frame data of the MAP sensor (if available).

    NOTE: Freeze Frame data is the PCM recording a fault when it happens. It captures the readings of the various PIDS (parameter identifiers)available to troubleshoot what happened. It's like a recording of the problem as it happened. At idle a typical MAP sensor Voltage reading should be about a volt, and at WOT (wide open throttle) it should approach 4.5 to 5 Volts. As for the TPS, at idle, the voltage reading is about 1 Volt or less. As the throttle is opened the reading will increase to 4.5 Volts at WOT. Do the two readings make sense? For example, if the TPS reading on Freeze Frame data shows 2.5 Volts (indicating partial throttle) does the MAP sensor indicate a reading that isn't at either extreme? Using the Freeze Frame data (if available) compare the MAP reading to the TPS when the problem occurred. This can help you identify what happened

    If you have no access to Freeze Frame data then check if the MAP sensor voltage changes when you apply vacuum to it. You can do this by mouth or a vacuum pump. The voltage should increase as you apply vacuum. If the reading doesn't change as you apply vacuum, make sure there are no obstructions in the hose to the sensor. If the hose is clear, the MAP sensor is usually bad, but it doesn't rule out the following from causing the problem: Does the MAP sensor appear to be stuck at less than .5 Volts? Then:

    NOTE: This code shouldn't set if the MAP is stuck at extremely low voltage, however, I'm adding it in because there's no way to know for certain for which vehicles a low voltage condition may set a P0105.

    1. Inspect the wiring harness and MAP sensor connector. Repair any damage
    2. Unplug the MAP sensor connector. Also, at the PCM connector, remove the MAP sensor signal wire and check for continuity to the MAP sensor connector. If there is infinite resistance, then repair open in MAP signal circuit. If the signal wire has continuity to the MAP sensor connector, then check for 5 volt reference voltage to the connector and a good ground. If both are present, then re-install all removed wiring and replace the MAP sensor.

    Does the MAP sensor appear to be stuck at full 4.5 voltage? Then:
    1. Inspect the wiring harness for damage. Repair as needed
    2. Remove the MAP sensor signal wire from the PCM connector. With a voltmeter measure the voltage with KEY ON ENGINE OFF. Is there 4.5 Volts? If so, unplug the MAP sensor and recheck. If it is still present, then repair short between the signal wire and 5 volt reference wire.
    3. If unplugging the MAP sensor causes the voltage to disappear, check that the ground is intact. If it is, then replace the MAP sensor due to internal short.

    MAP sensor codes include P0106, P0107, P0108 and P0109 .

    Manifold Absolute Pressure (MAP) Sensor: The MAP sensor is located against the firewall to the left side of the engine.
    Barometric Pressure Sensor: This sensor is installed on the VAF sensor; Volume Air Flow Sensor Is located in the air intake plenum assembly.

    Hope this helps.

    PO106 code GM what is that

    P0106 - MAP/Barometric Pressure Circuit Range/Performance Problem

    The Powertrain Control Module (PCM) uses the Manifold Absolute Pressure Sensor (MAP) to monitor engine load. (NOTE: Some vehicles have a Barometric Pressure (BARO) sensor that is integral to the Mass Air Flow (MAF) sensor and do not have a MAP sensor. Other vehicles have a MAF/BARO and a redundant MAP sensor where the MAP sensor functions as a backup input in case of MAF failure.) The PCM supplies a 5 Volt reference signal to the MAP sensor. Usually the PCM also supplies a ground circuit to the MAP sensor as well. As the manifold pressure changes with load, the MAP sensor input informs the PCM. At idle the voltage should be 1 to 1.5 Volts and approximately 4.5 Volts at Wide Open Throttle (WOT). The PCM looks for any change in manifold pressure to be preceded by a change in engine load in the form of changes in throttle angle, engine speed, or Exhaust Gas Recirculation (EGR) flow. If the PCM doesn't see any of these factors change while detecting a rapid change in MAP value, it will set a P0106.

    Potential Symptoms: The following could be symptomatic of a P0106:
    * Engine runs rough
    * Black smoke at tailpipe
    * Engine will not idle
    * Poor fuel economy
    * Engine misses at speed

    Causes: A P0106 could be caused by:
    * Bad MAP sensor
    * Water/dirt intrusion affecting MAP sensor connector
    * Intermittent open in the reference, ground, or signal wire for the MAP sensor
    * Intermittent short in the reference, ground, or signal wire for the MAP sensor
    * Ground problem due to corrosion causing intermittent signal problem
    * A break in the flexible air intake duct between the MAF and the intake manifold
    * Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities)

    Possible Solutions: Using a scan tool, watch the MAP sensor value with the key on, engine off. Compare the BARO reading with the MAP reading. They should be roughly equal. The voltage for the MAP sensor should read approx. 4.5 volts. Now start the engine and look for a significant drop in the MAP sensor voltage indicating the MAP sensor is working.

    If the MAP reading doesn't change perform the following:
    1. With the Key on, engine off, disconnect the vacuum hose from the MAP sensor. Using a vacuum pump, pull 20 in. of vacuum on the MAP sensor. Does the voltage drop? It should. If it doesn't inspect the MAP sensor vacuum port and vacuum hose to manifold for a restriction of some kind. Repair or replace as necessary.
    2. If there are no restrictions, and the value doesn't change with vacuum, then perform the following: with the Key on and engine off and the MAP sensor unplugged, check for 5 Volts at the reference wire to the MAP sensor connector with a Digital Voltmeter. If there is none, check for reference voltage at the PCM connector. If the reference voltage is present at the PCM connector but not the MAP connector, check for open or short in the reference wire between MAP and PCM and retest.
    3. If reference voltage is present, then check for existing ground at the MAP sensor connector. If it isn't present then repair open/short in the ground circuit.
    4. If ground is present, then replace MAP sensor.

    Other MAP sensor trouble codes include P0105, P0106, P0107, P0108 and P0109.

    I hope this helps to solve it (remember to rate this answer).

    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

    Run this diagnostic
    Test Procedures 
    1. Check if DTC P0110 is set in addition to DTC P0105 or P0106. If DTC P0110 is set, go to next 
    step. If DTC P0110 is not set, go to step 3 . 
    2. Turn ignition off. Disconnect MAP sensor 4-pin connector. Measure resistance between ground 
    and MAP sensor connector terminal No. 4 (Green wire). If resistance is one ohm or less, replace 
    MAP sensor. If resistance is more than one ohm, repair open in Green wire between MAP sensor 
    and ECM connector terminal No. 48. After repairs, clear DTC and verify MAP sensor operation. 
    3. Turn ignition off. Disconnect MAP sensor 4-pin connector. Measure resistance between MAP 
    sensor connector terminals No. 1 and 4 (component side). Resistance should be about 30,000 
    ohms. If resistance is as specified, go to next step. If resistance is not as specified, replace MAP 
    sensor. After repairs, clear DTC and verify MAP sensor operation. 
    4. Turn ignition on. Measure voltage between ground and MAP sensor connector terminal No. 2 
    (Red wire). Voltage should be about 5 volts. If voltage is as specified, go to next step. If voltage is 
    not as specified, repair open in Red wire between ECM connector terminal no. 44 and MAP 
    sensor connector terminal No. 2. After repairs, clear DTC and verify MAP sensor operation. 
    5. Turn ignition off. Disconnect ECM 63-pin connector. Check for continuity between ground and 
    MAP sensor connector terminal No. 1 (Green wire). If continuity does not exist, go to next step. If 
    continuity exists, repair short to ground in Green wire between MAP sensor and ECM. After 
    repairs, clear DTC and verify MAP sensor operation. 
    6. Reconnect MAP sensor connector and ECM connector. Turn ignition on. Backprobe MAP sensor 
    connector and measure voltage between ground and MAP sensor connector terminal No. 1 (Green 
    wire). Voltage should be 0.2-4.5 volts. If voltage is as specified, go to next step. If voltage is not 
    as specified, replace MAP sensor. After repairs, clear DTC and verify MAP sensor operation. 
    7. Check ECM connector for loose or damaged terminals. If problem exists, repair ECM connector. 
    If problem does not exist, replace MAP. Clear DTC and verify system operation. If problem still 
    exists, replace ECM. After repairs, clear DTC and verify system operation.

    Good luck and hope this helps. If the car does not start diconnect the MAP sensor to get you to the parts store if you need it to get you there.
