2002 intrepid vacuum issue p0108

Between the mass air flow sensor and the manifold is a vacuum line that runs down to a black pod (about the size of a soda can) what is this?could it be responsible for the code of p0108?

Got p0748 p0108 code on my 04 honda odyssey. Car sat for about one year. Replaced fuel pump yesterday and it started right up. Can I get info on locations of where sensors are?


PO 748
service the transmission .....check solenoids

- Dirty transmission fluid - Low transmission fluid level - Faulty line pressure solenoid valve 'A' - Line pressure solenoid valve 'A' harness is open or shorted - Line pressure solenoid valve 'A' circuit poor electrical connection

P0108
is the code for a problem with the MAP electrical circuit sensor having too high voltage input to the Engine Control Unit (ECU). This means that the voltage input to the ECU is too high and that it is not in the correct range for proper engine operation to work with inputs from the Mass Air Flow Sensor (MAF) and Throttle Position Switch (TPS).

1996 gmc sierra 5.7L what would cause engine codes p0102, p0108, p0121,p0300 at same time?


p0102 is MAF mass air flow , circuit low input. Try these to reset code by trying following.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Inspect for any air leaks near the MAF sensor. Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor. Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor.

Get codes p0068 and p0108


codes p0068 refer to Manifold pressure sensor/mass air flow sensor--throttle position correlation--causes ---wiring---map sensor---maf sensor--mechanical fault.
code p0108 refers to manifold absolute pressure(map) sensor/barometric pressure (BARO) sensor--high input. causes ---wiring short to positive---map sensor---baro sensor---ecm.

2002 Kia Sedona Intake Manifold going in a mist and won't idle right?


check air or a vacuum leaks and mass air flow sensor(MAF). dirty sensor not read air flow accurately and affects the EGR valve to close and allowing so much flow.

Where is the location of mass airflow sensor on 1988 ford bronco2


This engine doesn't use a MAF sensor, it uses a different kind of sensor to measure air flow, it is called a MAP (manifold absolute pressure) sensor, it is about the size of a pack of smokes and has a single 7/32" vacuum hose going to it from the upper intake manifold, it should be on the engine compartment fire wall. See picture below.

Chech engine fault PO108 Circurt High Voltage Whats the repair


The Engine Control Module (ECM) has detected a performance fault with the Manifold Absolute Pressure (MAP) sensor

The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both. .

Symptoms of a P0108 DTC code may include:
MIL (Malfunction Indicator Lamp) will likely be on
Engine may run poorly
Engine may not run at all
Fuel mileage may decrease
Presence of black smoke at exhaust


Potential causes of a P0108 code:
Bad MAP sensor
Leak in vacuum supply line to MAP sensor
Engine vacuum leak
Short on signal wire to PCM
Short on reference voltage wire from PCM
Open in ground circuit to MAP
Worn engine causing low vacuum

Possible Solutions: A good way to diagnose if the MAP sensor is to blame would be to compare the KOEO (key on engine off) MAP sensor reading on a scan tool with the Barometric pressure reading. They should be the same because they both measure atmospheric pressure.

If the MAP reading is greater than 0.5 volt off of the BARO reading, then replacing the MAP sensor would likely fix the problem. Otherwise, start the engine and observe the MAP reading at idle. It should normally be about 1.5 volts (varies according to altitude).

a. If it is, the problem is likely intermittent. Check all the vacuum hoses for damage and replace as necessary. You can also try wiggle testing the harness and connector to reproduce the problem.
b. If the scan tool MAP reading is more than 4.5 volts, check the actual engine vacuum reading with the engine running. If it is less than 15 or 16 in. Hg, then the PCM is probably not seeing enough vacuum (due to a worn engine, perhaps) for a given operating condition (which causes a higher than normal voltage signal to the PCM) and setting the code. Repair the engine vacuum problem and retest.
c. But, if the actual engine vacuum reading is 16 in. Hg or more, then unplug the MAP sensor. The scan tool MAP reading should indicate that there is no voltage present. Check that the ground from the PCM is intact and also that the MAP sensor connector and terminals are tight. If the connection is good, then replace the map sensor.
d. However if, with KOEO, & the MAP sensor unplugged, the scan tool shows a voltage reading, then there may be a short in the harness to the MAP sensor. Turn the ignition off. At the PCM unplug connector and remove the MAP signal wire from the connector. Re-attach the PCM connector and see if with KOEO, the scan tool MAP reading shows voltage. If it still does, replace the PCM. If not, check for voltage on the signal wire you just removed from the PCM. If there is voltage on the signal wire, find the short in the harness and repair.

I have a 2002 GMC Sierra 1500. 4.3 liter engine. I brought it to autozone and they put the gauge on it and got two codes P0140 and P0300. I had my distributor cap replaced, ignition rotor, plugs ,wires,...


Clean mass air flow sensor with a nonchlronated brake cleaner,install new air filter and check all vacuum lines for leaks then check for vacuum leak around or at intake manifold.Code P0140 is for mass air flow sensor code P0300 is a multiple misfire which more than likely is a vacuum leak possibly intake manifold gaskets leaking.

2006 range rover hse is displaying diagnostic code P0110, P0108, and P0104. What are they? Also, is there a place where I can get a list of all the codes?


try looking on directconnect file share and you can then download mine ,programme available for free download at sourceforge.net

P0110....Intake Air Temperature Circuit


P0108....Manifold Absolute Pressure/Barometric Pressure Circuit High Input


P0104....Mass or Volume Air Flow Circuit Intermittent

think this is telling you you need a new mass air flow sensor

I have a fault code of p0108 what has caused this fault and how do i fix it on my mazda mpv


Your map sensor, otherwise known as mass air flow sensor is probably bad. You should replace it. it is normally located between the air filter and the throttle body. It senses how much air is going into the throttle body so the car knows how much fuel to inject.
