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

ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........

• P0103
  Mass Air Flow Sensor Circuit High Input
• Possible causes
• 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.
• possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
  - Engine stall
  - Engine running rough
  - Excessive fuel consumption
  - Excessive smoke
• the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).

2003 NISSAN Altima Sedan OBDII Codes List

Check to see if the check engine light is on. Then double-check your vacuum lines. Another thing it could be is the MAF ( Mass Air Flow ) sensor. 90% of the time the Mass Air Flow sensor heated element which meters the air so the computer can add the proper fuel mixture has fallen out of specification. It will cause the Air and fuel mixture to be so off it can cause Stalling, poor acceleration, won't rev over a certain rpm, and running issues. You should have the Air and Fuel mixture readings checked to verify. If found to be bad, do not replace with a After Market one. After market, MAF sensors never seem to work properly. Their heated element doesn't work right, which can cause 02 sensors to flat line and have you chasing your tail trying to figure out what is wrong. So the only way to correct this issue if you do have a bad MAF sensor is to replace it with an OEM.

hello good day, reverse your air filter, make the bottom to top,, if is not work change the high tension wires

bad fuel filter maybe or air filter or you need new spark plugs or wires or a new distributor

I'm having the same problem. At first I thought it was bad fuel so I replaced the fuel filter to no avail. Then I cleaned the Mass Air Flow sensor which also didn't work. Is your check engine light on?

The filter is located eather under the car at the driver or rider side door.

Other probs can be
Bad fuel pump
Clogged air filter.
Clogged injectors
Water in the fuel tank.
Clogged catalytic converter
Bad MASS air flow sensor
Bad Throttle position sensor
Timing is off

If there is a Mass Air Flow sensor in the intake ducting.Was it off with CRC electrical spray clesner. Don'rub or brush to clea. spray onlty and air dry. No compressed air. Make sure the air filter is clean. See how that works. Good Luck -Ned-

could be the oxygen sensor manybe, or fuel pump

check the actual fuel line. Also is it fuel injection or carberator
