You wouldn't happen to have a wiring schematic for the mass airflow sensor
SOURCE: mass air flow sensor replacement (variable valve timing)
The MAF is on the Air Intake above the air filter box and screwed into the plastic tube heading toward the throttle body. It is the 2" by 2" plastic protrution from the air intake tube. There should be two philips screws holding this in. Remove the two screws and back the entire MAF out. There is a wire harness connected, unclip this to remove completely.
If you have money burning a hole in your pocket, go ahead and purchase another MAF for a few hundred clams, or you can spend about $10 and clean it. It's made out of titanium and I doubt it will fail in 10 years. But sometime it does happen.
Go to Lowes, or Home Depot and buy Electronic Cleaner in a spray can. If you look inside the sensor, there is a heated wire, and behind that is another wire which picks up the oxidized air.
Stick the tube which is attached to the electronics cleaner spray can into the cavity where these wires are seen. Continue to spray most of the can onto these wires to remove oxidation build up from the wires. Let it evaporate for a few minutes then hit it again.
Allow the assembly to evaporate complete for about an hour.
In the mean time, take some throttle body cleaner and spray out the throttle body with the valve open. Keep open to let it dry out quicker and clean up the black crud that come out.
Keep you air filter replaced.
Put everything back together and you should be good to go.

SOURCE: Where is the mass air flow sensor located on a jaguar x-type
hi from the uk the location of mass air flow sensor on x type jag is as follows==it is on the r/h/side of the air filter cover with jaguar embossed on top? this sensor is just prior to the intake hose that connects to the motorised throttle body from filter connections underneath it to unplug and meter is held by two screws ?if memory serves ? may i suggest you remove the large hose and use a little wd40 or similar to clean /lubricate the throttle butterfly in throttle body throat at this point so as to prevent future sticking upsetting of idling ? hope this helps ?

Very easy for the Mass Air Flow Sensor....it is in the duct between the throttle body and the air filter box. Just unclamp the tube and remove the old and replace with the new.
On your pack....I need the engine size.
SOURCE: location of mass air flow sensor
The sensor is mounted on the throttle body between the air cleaner assembly and the air cleaner outlet tube.

Image Mass Air Flow(MAF)Sensor
PURPOSE
The Mas s Air flow (MAT) sensor
measure s the amount of air flowing into the engine.
This value is used by the
Powertrain Control Module (PCM) in calculating the required
Fuel injector pulse within order
to provide the desired air fuel ratio. This input can also
be used in determining
Electronic Pressure Control (EPC). Shift and torque converter
clutch scheduling.
CONSTRUCTION
The MAE sensor is located
directly in the airflow path between the air cleaner housing
and the throttle body. Ail air
entering the intake manifold must pass through the sensor.
Located in the MAT sensor
directly in the airstream are two platinum wires, a hot wire
heated by electrical current and
a cold reference wire. The MAF sensor uses the air flow
across these wires to calculate
its output.
OPERATION
The hot wire is maintained at
200CC (392CF) above ambient temperature as measured by
a constant cold *e. The current
required to maintain the temperature of the hot wire is
proportional to the air mass
flow. The MAE sensor then measures the amount of
electrical current required to
maintain this temperature difference and converts this
value to an analog DC voltage.
This output varies directly with the mass air flow rate.
Pay attention to the Paragraph about the torq converter.

replaced mass air flow sensor on 1994 nissan quest gxe....need wiring diagram to figure out which wire goes where....no connector, just 3 wires
