Where are the mass air flow sensor located

The mass air flow sensor [aka MAF] is located inside the tapered section of your air cleaner housing. Look for the round clamp with a lever that holds the two parts of the air cleaner box together. Loosen this clamp and take the air cleaner apart. You will notice that the tapered section has several wires going into it. Once you have it apart. Those wires will lead you to the MAF.

Map senser ware is it no my car

It's called a MAF sensor. You can clean the short heated wires inside with a can of spray carb cleaner. Do not touch the wires. They get coatedwith varnish and make the car hesitate. Sometimes turns on CEL light, DTC codes P0171 or 74.

4 nuts hold the housing on.

Mass Air Flow (MAF) Sensor The mass air flow sensor (MAF sensor) (12B579) :
  • is located between the engine air cleaner (ACL) (9600) and the throttle body (9E926) .
  • uses a hot wire sensing element to measure the amount of air entering the engine. Air passing over the hot wire causes it to cool.
  • sends an analog voltage signal to the powertrain control module (PCM) (12A650) to determine the intake air mass. The powertrain control module will then calculate the required fuel injector pulse width in order to provide the desired air/fuel ratio.
The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly.

I have a 1997 ford expedition 5.4 L with the check engine codes of PO153 and PO133 coming on.... the truck stalls and jumps need to know what part to replace or how many i need?

PO -133 O2 Sensor Slow Response

Po -- 153 same thing

Check for vacuum leaks --every where

Clean MAF Sensor -CRC MAF Cleaner

Replace the 2 --front O2 Sensors, if over
100,000 miles on them The ones closest to motor

Use the OEM Type not the cut & splice
universal junk

NAPA can order them
Should be Bosch or NGK

Codes do not tell you anything about what is wrong
or what to replace.

Location of mass air flow sensor on a 2002 pontiac firebird

It should be along the air intake. A block box about 1 1/2" x 2 1/2" held on by 4 ? screws. Easy to replace, but kind of pricey. They make a product for cleaning them. Try that first. Do not touch the wire resistor that goes into the intake. It's delicate.

I have a 2003 ford expedition,

if you have the 3.8 engine you might have a vacuum leak at the intake where the plastic intake meets the lower intake,there are rubber gaskets that fail when they get older from oil getting into intake.This will set that po171 also p0172 -3 &4,hope this helps as you may be wasting time and money to try and fix it with just the o2sensor .The maf on the ex is where the cone air filter is look for the wiring harness that goes into air filter housing,its inside there fun to remove dont brake it

There are alot of things that could cause pinging but the most economical and easiest thing to try first is to clean the MAF sensor.Remove the MAF and clean the sensor bulbs with a good electrical cleaner and light shop air or just let it totally air dry then hook it back up and do several wide open throttle burst to reset the baro readings.
