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

Hi Eddie,Here's a link to a Nissan part site,the starter relay is 25224G.If you look at the truck picture,it has letter's,find letter G AND THAT'S WHERE THE STARTER RELAY IS,BY THE WAY,i HAVE A MINT 85 nISSAN 720 4X4,HERE'S A VIDEO OF IT,TAKE CARE. Parts found for 1996 Nissan Hardbody Pickup 1995 1997 Body Electrical Relay CHECK MINE OUT. 85 Nissan 720 4x4 2 4 Weber conversion

Belief this is a petrol engine, IAT sensor can be in the MAF sensor housing, or intake hose or even the intake manifold. Depends on engine type and year.

Basically the timing chain in every vehicle is set up on the following principal No 1 cylinder is at TDC on compression stroke " meaning both valves intake and exhaust are closed and the ignition rotor should also be lined up with No 1 ignition lead . On the timing chain sprockets there will be a mark on each that align or point to each other and u fit as such.
As long as u make sure your on no 1 cylinder compression stroke and cyl is at top dead centre then line up the sprockets u'll be sweet

Check the brake fluid level in the master cylinder reservoir.
Low brake fluid level can cause both lights to come on and stay on

check for possible vaccum leak/vaccum hoses/intake gasket/throttle body gasket.hope it helps.sheppardart6

needs to be either in the air ccleaner or intake ducting

I have fix this problem before it was my boss truck the problem was with the intake leak it was sucking air trow the intake try get a piece or hose and get close to the intake and see if your heard some sucking noise and also I did replaced the mass air flow sensor was bad and is on top of the electronic carburator injectors but when the air flow sensor is bad your truck don't seems to be stable at low rpm's and they do the same thing with an intake air leak so look for those 2 problems you may have only 1 of this cyntom but 1 is enough
