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

    Jumpy throttle still, i had dealership run diagnostics on it. they said to replace tps sensor and mass airflow sensor. they wanted an arm and a leg so i went and got the parts from advance auto parts and...


    yeah its pretty easy to change the mass air flow sensor. find the mass air flow sensor on your air intake an un screw it a n disconect the cable an replace. the tps...... if you are looking at the motor (standing in front of front bumber looking at the engine top right side of motor you will see the throttle sensor an all you have to do is un screw and put new one in. it should just fit right in with no problem.

    My 1998 ford taurus wagon misfires when I step on the gas at 30mph and about- occassionally the service engine soon light blinks


    clean the MAF sensor heated wires inside MAF with carb cleaner gently with a toothbush first. Then disconnect battery for 1 hour and reconnect and drive for 10 miles so computer can relearn clean MAF sensor.

    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.

    Runs rough when cruising at 35-40 mph


    try pulling off the air breather hose and look inside at the mass air flow sensor,it looks like a wire with a diode hooked to it incase you didnt know,see if there is any fuzz on it,sometimes the air filter will lose small pieces and the mass air flow sensor catches it.If that doesnt work then you may have a fuel problem,weak pressure,causing the mass air flow sensor to read too much air so it tricks the computer to adjust the issue.
