A P0300 code is a random cylinder misfire code and could be caused by a bad plug, plug wire, or fuel injector. The P0171 is bank one o2 sensor is reading lean w/ both of these combined could mean a vacumm leak.. Hope this helps.

the p0300--p0301-p0302=p0303 are misfire codes and can mean needs tune up or wiring problem and p0171 is system to lean bank 1 with this code if you correct it will probably correct the misfire codes your receiving

I have a 2007 Chevy hhr and the codes are p0102 p0113 p0171 and p0300 it won't start when I first turn the key but when I do it the second time it starts up so what could be the problem


p0102 is your Mass Air Flow device.
p0113 is "air intake temperature" sensor voltage too high.
p0171 is "engine running too lean"
p0300 is "random misfire"

You can pretty much ignore your p0113, p0171 may be caused by a bad MAF, and p0300 may be caused by your p0171.

the actual indication for your MAF is that the voltage getting to the computer from the MAF is too low. It could be a bad MAF, or bad wire between the MAF and the computer.

Multiple engine codes 2002 tribute. p0171, p0174, p0300, p1401


I doubt it.
Codes 171 and 174 are for lean fuel mixtures, 300 is for random missfires which could be fuel or ignition related, and 1401 is for a problem with the EGR valve system. Now the EGR could cause the other codes if the valve is open or leaking when it should be closed.
The EGR valve and sensor would need to be tested first.

Code0171 system too lean on 2004 chevy avalanche


P0300 Means randome miss fires detected; Cause is you may need a tune up.Or you just drove over one very bumppy surface. P0171 is caused by the unburnt fuel from the misfire.

5 ERROR CODES ON A 2002 CHEVY SUBURBAN P0102,P0171,P0174,P0300,P1518 ??????HELP!!!


Change the Mass Air Flow sensor.Or the the Volume Air flow sensor.Also replace the ( IAC ) Idle Air Control. There is no code P1518 are you sure they wrote it down for you correctly? I just had my Library of codes updated last week and it is not on the list. After all repairs are made make sure you have the Diagnostic Trouble Codes Erased from the on board computers memory. This will reset the check engine light and keep it from comming on again for thoes codes.If it does come on again and it relays more DTC you can ask me for further help through the Reply Window. Good Luck and have a good XMASS.

2003 Ford Ranger 4x4 extended cab- diagnostics checked and got these codes- P0171, P0174, P0300, P0316. Can you tell me what they mean?


P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure

Codes 1133-0131-0171-0300


p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.
