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

1993 Mitsubishi 3000gt when mass air flow sensor is plugged in car wont rev past 2500 rpm car was bought with it unplugged. Replaced the mass air flow sensor an still does it. When its unplugged it runs...


The computer only knows the voltage across what it thinks is the MAS. A bad wiring connector and a bad MAS is all the same to the computer. I would change the harness to the MAS before I spent any time or money on any other problem solving.

91 mitsubishi 3000gt seems to idle ok, but has no power and will not go faster than 40mph.


sounds like you may have a plugged up exhaust or catalytic converter. Try removing the o2 sensors from exhaust pipes and see if it runs better. If it was a timing issue it would idle bad.

P0103 HYUNDAI - Mass or Volume Air Flow Circuit High InputPossible causes- 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
Tech notesBefore 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.
P0112 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Low InputPossible causes- Dirty air filter
- Intake air temperature (IAT) sensor harness is open or shorted
- Intake air temperature (IAT) sensor electrical circuit poor connection
- Faulty intake air temperature sensor
When is the code detected?An excessively low voltage from the sensor is sent to ECM.

What causes the engine is at normal operating temperature idle roughly and die?


I would check the mass air flow sensor that is located on the air intake (its the box in line on the air intake with wires going into it) with the engine running take a screw driver and smack the mass air flow sensor with the handle... if the engine stalls or starts running real rough that might be the culprit.

Mitsubishi 1994 3000GT idles rough when u try to push the gas petal it dies


I'd try cleaning the mass air flow sensor and check its connections too. Also if you have the car checked for any engine codes this may assit. You may have a heavy vacuum leak too... As for now I'd check the MAF
This is located on the air intake just after the air filter.
I hope this may have helped,

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).

Iat sensor


Yes and No , It does, however it is integrated into the Mass Airflow Sensor . So its not per say a separate component that you can replace without replacing the MAF unit .Excuse me , Mitsubishi wants to call it the "Volume Air Flow Sensor" , not Mas Airflow Sensor , as we know it . . I stand corrected .
