Where is the mass air flow sensor located on a jaguar x-type

MAF stands for Mass Air Flow. Your MAF meter is located in the inlet snorkle between the air filter housing and the throttle body.

m.a.f is mass air flow, sensor located in induction pipe near battery,check wires at sensor connector as these are prone to braking.E.G.R. is exhaust gas recirculation.valve located at left front of engine as you look under bonnet and are prone to getting clogged and sticking, may need renewing, failure causes excess exhaust smoke.

P0112 is the code for a intake air sensor problem. If you can buy one seperate it will be located between the Air filter and the Throttle Body ... usally near the Mass Air flow sensor . I am a Jaguar Tech our are located inside the Mass Air sensor . Also ck the actuall housing of the air filter assembly

either snorkel air box or manifold

Rather than take a stab in the dark replacing items - get the codes scanned and this should show what area the fault lies in. Normally if there is a fault with the MAF (mass air flow meter) it would normally show as a check engine light (MIL) - is this warning on? So many things can affect these engines from O2 sensors, coil misfires, bad cable connections etc etc. - so best move get the car scanned. Hope this helps (and saves money) good luck.

TheMobilian, Yes, the Mass Air Flow is a Hot Wire type. There is a spray made for the mass called mas air flow cleaner. Regular cab cleaner is too harsh and can eat the coating inside mass air flow and it's delicate parts. Use throttle bore foam cleaner; it works like bathroom scrubbing bubbles and eats the gum and varnish. When engine warms up (closed Loop) both sensors work together giving input to ecm for output. Have someone with a live data reader read both sensors. (Let me know the readings?)

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.

Hi:
The mass air flow sensor is a round sensor that is mounted in the air intake, between the air cleaner box and the engine throttle body.

check the air mass sensor from air filter to engine

MAF stands for mass air flow sensor, this is used to tell the computer how much air is entering the engine, check the air filter,and clean the sensor with CRC mass air flow cleaner, with engine off. hope this helps,let me know Ray
