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

What are the probable causes of DTCs P0300 and P0316?


code p 2274 refers to heated oxygen sensor(HO2S) 3 bank 1 signal stuck lean or oxygen sensor(O2S) signal stuck lean===causes for both--wiring ---HO2S--fuel pressure --injectors --intake leak
code p 0300 refers to random /multiple misfires detected ===causes --spark plugs -- HT leads injector/s--ignition coils --low compression --wiring
code p 0316 refers to misfire detected during start up---first 1000 revolutions ===causes --engine mechanical fault---wiring---ignition / fuel system---injector
in all codes the injectors show up as a problem cause and if you couple that with low fuel pressure issues you may have a pointer to the real cause
have a pressure test done on the fuel manifold top check for pump fault , filter blockage and faulty pressure regulator
check /clean injector tips as they could be suffering from contamination problems and not operating freely ( good fuel injector cleaner)

I have a 2000 Mitsubishi Galant and it's reading a P0170 code. I had the oxygen sensor replaced a year ago and one mech thinks it's the fuel tank pressure sensor. How can I access this or fix the problem....


Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection
If you have a K&N filter, the code may actually be caused because it was over oiled.

Why does my GM Vortec 6.0 LQ4 Engine light comes on at the start, then flashes on movement at acceleration. Check ignition coils (replace them), spark plugs (replace them), wires (replace), clean fuel


Instead of playing the part swap game an not fixing the problem ,wasting money ,making part stores rich etc.. . Take it to a qualified repair shop that know's how to diagnose misfire problem's .

Brain box


The misfire causes unburnt fuel and air to pass by the oxygen sensor. The sensor sees the oxygen and thinks more fuel is needed, so it adds gas. Focus on the misfire, bad spark plug, ignition coil, plug wire. A clogged fuel injector also causes a misfire but less common.

My '01 impala 3.4 v-6 flat spots when COLD, at around 20mph. the idle is ruff with random misfires. acceleration is overall poor. when HOT, most symptoms go away leaving only some slight acceleration...


depending on mileage, but possible tune-up could fix it. if already done then check ignition coil pack and ignition wires also spark plugs, check vacuum hoses for leaks or porous, last injectors clogged - use some techron fuel injector cleaner (wal-mart has them). Also get the throttle body and iac valve cleaned by throttle cleaner . Also this other possibilities are to be checked and confirmed.:---- Engine running rough or misfiring can be cause by the following:

1.Defective spark plugs
2.Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4.False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Manifold absolute pressure sensor
12.Mass Airflow Sensor
13.Idle air control valve

2001 silverado po300 code and po135 code changed 2 o2 sensors still coming up have not changed driver side o2s yet


Well the P0300 code has nothing to do with your O2 sensors just a heads up.

P0300: Random/Multiple Cylinder Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

Causes:
- Improper spark plug
- Insufficient compression
- Incorrect fuel pressure
- The injector circuit is open or shorted
- Fuel injectors may be faulty
- Intake air leak
- The ignition signal circuit is open or shorted

Solutions:
- Perform Injector Service
- Replace Spark Plugs
- Replace Injectors
- Replace Ignition Coils

P0135: O2 Sensor Heated Circuit Malfunction Bank 1 Sensor 1

The front heated oxygen sensor (or sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Front Heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 1 usually takes care of the problem

Hard start on cold mornings; replaced plugs but did not fix; fuel filter?


If the vehicle runs normally otherwise, your fuel filter is likely not the problem. A plugged fuel filter would likely cause misfiring under load, such as when going uphill.

Make sure, by the way, that you do not touch the gas pedal when starting. That could make it hard to start.

Old fashioned cars used a choke to feed it more fuel for a cold start. Modern cars use a computer to feed the fuel injectors more fuel on a cold start, and rely on a sensor or two to know that it's cold.

Couple of possibilities here:

a) Has the check engine light been on? If you have a bad sensor, such as oxygen, throttle position, or coolant temp sensor, the computer may have an error code stored in it's memory about this.

b) How many miles on the vehicle? Some other problems could be leaky injectors, leaky injector 0-rings, or intake manifold air leaks, all making it difficult to start when cold.

A fuel pressure gauge on the fuel rail would tell you if a leaky injector is causing the fuel pressure to drop....then a cold start would be difficult if there is no pressure in the system.

If there is a leaky o-ring or intake manifold, the vehicle will typically misfire and/or light a check engine light.
