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

Low heat good air flow


It is possible the engine thermostat is faulty and preventing the engine from getting hot enough to provide a good heater temperature.

It is possible the air mixing flaps aren't working correctly.

It is possible the heater matrix is partially blocked, has developed a thick internal coating or an air lock is preventing the circulation of hot coolant.

08 equinox low heat


Low or poor heat usually means your thermostat is stuck open. To check with a cold engine, remove the rad cap and start the engine look inside there should be no water flow, if its flowing the stat is open.

Low air flow to feet when heat is on ?


Sounds to me that you might have a leak in the line. Those heaters are all Vacume actuated.

Loosing anti freeze engine over heating


replace the viscous fan hub or check the electric fan operation as you do not have a forced air flow at idle. When the engine is working hard at low revs (pulling up hill) there is insufficient road air flow and at idle at lights there is no road air flow

No heat in car


Check low antifreeze level--- Replace thermostat-- heater coil plugged, check for flow through heater coil, heater coil outside plugged no air flow replace air filter in dash and clean outside of heater coil if you have very low air movement to defrosters--- try this last thing first --- cheapest things first ,

2004 kia spectra has blowing air but know heat.


Heat and air conditioning are in separate systems. If you aren't getting heat, the first step is to check your coolant level. Low coolant can result in improper flow through the heater core. If you do have low coolant, be on the lookout for a coolant leak! If your coolant isn't low, then there is going to be an issue with circulation through the heater core. The heater core could be clogged in some way or another.1

Very low air flow through vents despite the fan working well


It is very likely that the Air conditioner evaporator core is restricted due to leaves or some other object may be blocking air flow like a plastic bag, does it do this on both outside air and recirculation setting?

No air flow through 4 top rear vents


Don't worry, it's designed that way. The owner's manual is pretty unclear about this. But the heated air only comes out the floor vents underneath the front seats and the "heat vents" at the forward and side of the rear A/C compartment near the floor. The cooled or vent air flows from the overhead vents.

The problem is the blower motor speed control resistor, it is located near the blower motor in the housing.
