Not all the diagrams are available online.

To get the F250 complete wiring diagrams you need to get the Haynes, or the Chilton repair manual for this model.

You can buy it for a small fee from links below:

Where map sensor located


there is no MAP for fueling the ECU uses MAF for air flow.
there is a MAP for EGR only. called a different name. do to that fact.
nice guess,
why not post symptoms.????????????????
this engine fuels mostly off the MAF.
ture air flow.
need maf test page got it.

Locating MAF on 2001 alreo


Honda's do not use a mass air flow (MAF) sensor. They use a manifold air pressure (MAP) sensor. The MAP sensor measures vacuum vs the MAF sensor measuring air flow/temperature. No real reason to clean a Honda MAP sensor. Are you having engine performance/idle problems? --------------------------------------------------------------------------------

Map sensor location


Located on top cylinder on transmission side.The MAP sensor is located either directly on the intake manifold or it is mounted high in the engine compartment and connected to the intake manifold

Common fuel problems in a 2000 cadilac escalade


You problem reside in the cause of the fuel injector not getting the proper amount of fuel this can be caused by the MAP (manifold absolute pressure). To a MAF (mass airflow) you have both sensor, Disconnect the MAF does it stay running and also inspect the MAF air duct for cracks and false air leak,From the MAF to the throttle body. with the MAF disconnected and it stay running the MAF is the solution ,as for the MAP if it can stay running with the sensor disconnected the MAP is the solution

clear the codes and read then after about 10 miles or so, you can clean the MAF, MAP, but you can test the temp sensor, I would clean the MAF, the car isn't going to fix it's self, the sensors need to work for your car to run properly.

I have a 2000 impale and I've changed the fuel


For this vehicle its one or the other you are equipt with a MAF (Mass airflow meter) and a MAP(manifold air pressure) you problem will be one of these sensor, Start with the mass air flow disconnect this sensor its at the air cleaner air duct with this disconnected you should be able to accelerate(but not that good) if you can then this is the problem and a replacement is in order, Now here the tricky part the MAP is a back up just incase the MAF fails it monitor the EGR, If you disconnect the maf and it runs better you will need a maf sensor.if you replace it with a known working one and there is no difference you have a MAP problem.

1991 olds cutlass calais 2.5 engine ran the self dignostics and got code 33 need to what code 33 is.


It's the maf/map sensor circuit.
maf--- mass air flow sensor
map--- manifold absolute pressure.--- check the small vaccum hose from the map sensor to the source, could be brittle and leaking air.
Have both the map and maf sensor checked for proper voltage, one or both could be bad. A repair shop shouldn't charge much to do that.

Check engine light is on, not good acceloration


Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The computer detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds.
You will likely not notice any serious drivability problems, although there may be symptoms.
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
  • Inspect for the following conditions:
    An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components:
    - The secondary ignition wires or coils
    - Any solenoids
    - Any relays
    - Any motors
  • A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
  • A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
  • When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude.
  • A high resistance on the ground circuit of the MAP sensor can cause this DTC to set.
  • Any loss of vacuum to the MAP sensor can cause this DTC to set.

Where are the map and maf sensors located on a 1990 r2500 suburban?


your vehicle has a MAPS and not a MAFS, the MAPS will be passenger side of the intake manifold, above the valve cover and mounted on a bracket
