BK/WH - Ground (pin 3)

Red - to fuse 20 in power distribution box (maybe under hood) see owner manual (pin 2)

Tan/Lt Blue - signal return to PCM (computer) (pin 4)

Lt Blue/Red - signal (pin 5)

Don't know what your issue is but you should remove it and spray the 2 exposed wires inside with carb cleaner very good. Do not touch the heated wires. This will remove built up varnish and get rid of the lean mixture and P0174 lean codes.

Please rate if helpful.

    Yes, MAF sensor cleaner is better, but must people have easy access to carb cleaner. Actually, for our reman operation, they use steam to clean the wires.

P0101


P0101: MAF or VAF A Circuit Range/Perf

- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.

I need to know which 2 wires are the leads to the mass air flow sensor. colors would be nice to know


WELL FIRST OFF WHAT DO YOU MEAN BY LEAD IT'S MORE THAN LIKELY A 3 OR 5 WIRE MASS AIR FLOW SENSOR WHICH WIRES DO YOU NEED AND WHAT TYPE OF VEHICLE IS IT IT CAN VARY FROM MODEL TO MODEL

REPLACING mass air flow sensor


The mass flow sensor on the 1999 intrigue is along the intake tube right after the air filter intake housing. Loosen the two clamps that hold the MAF sensor between the Air filter box cover and air intake tube, disconnect the wire leads at the MAF sensor connection and remove the MAF. Note it's uncommon for the MAF sensor to go bad and 95% of the time, cleaning it with MAF sensor with MAF cleaner will fix any problem it may of had to trigger the DTC codes.
Start with trying to clean it first just by following the instruction on the MAF cleaner. This should save you time and money to get your Intrigue running 100% again soon.
Good luck and thank you for using Fixya.

Problem starting 1999 escort. has fuel, spark, timinging is dead on the money. acts like it will start but wont


Check the air mass meter or air mass sensor, also the crack sensor can cause this fault.

EGR valve but the car will normally still start with that fault. most common is the air mass sensor, you can just try and clean it first and check the wires to the sensor its most likely the air mass sensor or air related fault.

MAAS AIR SENSOR


A mass air flow sensor is used to find out the mass of air entering a fuel-injected engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature and altitude, and this is an ideal application for a mass sensor. (See stoichiometry and ideal gas law.)
There are two common types of mass airflow sensors in usage on gasoline engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with an additional sensor or two, the engine's air mass flow rate can be accurately determined.
Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0 - 5.0 volt or a PWM signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings.

What color is the intale air temp sensor wire on a 2002 Mitsubishi Eclipse GT, 3.0L V6, 5spd manual?


There are two wires for the intake air temperature sensor.

The sensor is built into the Mass Air Flow sensor near your air filter.

Pins 5 and 6 (wire colors brown and red/blue respectively) of the MAF connector are for the air temp sensor; Pin 6 is the 5V reference voltage from the ecu, pin 5 is the return signal (ecu input).

1999 Ford Explorer where is the Mass Air Sensor located


The airflow meter is in the air filter box.Unstrap the clamp to get to the filter and on the half thats connect to the hose which runs to the throttle body is where you will find it.There are wires that run into that half.

Need to find out what color the vss wire is under hood


you don't have a vehicle speed sensor (VSS). You have a wheel speed sensor that tells the PCM vehcile speed in place of the VSS. What are you tring to do?

The electronic engine controls consist of the following:
  • powertrain control module (PCM) (12A650)
  • throttle position sensor
  • idle air control valve
  • camshaft position sensor
  • crankshaft position sensor
  • mass air flow sensor
  • intake air temperature sensor
  • heated oxygen sensor—front
  • heated oxygen sensor—rear
  • knock sensor
  • cylinder head temperature (CHT) sensor
  • power steering pressure (PSP) switch
  • Wheel speed sensor
The powertrain control module needs the following inputs to calibrate the engine properly:
  • camshaft position
  • engine rpm
  • engine coolant temperature
  • amount of engine detonat

I have a 1999 oldsmobile intrigue that is misting a lot. It idels rough, and runs rough. I can still take off it is a little slow, but I can still go pretty fast, but it still mist at the high speeds...


fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck

1999 pontiac grand prix . will not run


If you unplug the MAF sensor it should run using the default mapping. I'm having the same problem, but I want to figure out why it won't run with the sensor connected.
