The electrical connection does have a clip that you will have to push in order to remove the sensor. Do not use any liquids to clean the MAF Sensor, compressed air only. Your vehicle will not run without it!

03 Nissan Altima showing codes P0304,P0102,P0154,P0113 what are they and how do i repair the problems.


Hi Chris.

p0304 = Number 4 Cylinder Misfire Detected

Faulty spark plug 4
Clogged or faulty fuel injector 4
Faulty ignition coil 4
Fuel injector 4 harness is open or shorted
Fuel injector 4 circuit poor electrical connection
Ignition coil 4 harness is open or shorted
Ignition coil 4 circuit poor electrical connection
Insufficient cylinder 4 compression
Incorrect fuel pressure
Intake air leak

The P0304 code means that the cylinder 4 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 4.


p0102 = Mass or Volume Air Flow Circuit Low Input

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

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.


p0154 = O2 Sensor Circuit No Activity Detected Sensor 1 Bank 2

Faulty Front Heated Oxygen Sensor Bank 2
Front Heated Oxygen Sensor Bank 2 harness is open or shorted
Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
Inappropriate fuel pressure
Faulty fuel injectors
Intake air leaks may be faulty
Exhaust gas leaks

Replacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem.


p0113 = Intake Air Temperature Sensor Circuit High

Faulty Intake Air Temperature (IAT) sensor
Dirty air filter
Intake Air Temperature (IAT) sensor harness is open or shorted
Intake Air Temperature (IAT) sensor circuit poor electrical connection

The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.



Hope this helps

Where is the Mass Air Flow Sensor located on a 2004 Mazda 6


Should be in line with the air intake. Locate air cleaner box. Follow large intake tube, rubber, about 3 inch diameter, to intake. Along the way look for a box in line. There should be an electrical connection going to it. That box should be the Mass Airflow Sensor. If you want to remove first disconnect battery to be safe and then disconnect the electrical connection. Should find a hose clamp either side of box. Loosen both and pull rubber tube back to release box. The actual sensor is inside. Just look through cener of box and you'll see something like a bar. The air flow sensor itself is much like a fragile ribbon of metal. VERY DELICATE. I've heard and headed that you should only use Mass Airflow Sensor cleaner as other automotive solvents are too harsh and leave a residue. The sensor can't tolerate any residue. In fact that's why you and I are about to clean it or have it cleaned. I'm getting Code P2187 Bank 1 Lean at idle. If the mass airflow sensor 'thinks' it has the correct amount of air but doesn't the injectors could be backing off delivery of fuel and assist in creating my 'lean' condition.

Hope this helps.

I have a 2000 excursion and sometimes wen I accelerate it starts chocking out at 2000 rpm and won't go any higher


Mostly your MAF MASS AIR FLOW SENSOR needs cleaning.
1st Disconnect the battery ground cable
then open the engine air cleaner.
  • Disconnect the MAF sensor electrical connector.
  • Release the air cleaner clamp.
  • Separate the inlet side from the outlet side of the air cleaner.
  • Remove the MAF assembly.
  • Disconnect the MAF sensor electrical connector.
  • Remove the nuts and separate the MAF sensor from the MAF sensor plate.
As shown

then follow the steps in the video.
HOW TO CLEAN A MASS AIR FLOW SENSOR

if that did not clear your engine chocking then make sure there is no Vacume leak.
hope that helps
