SOURCE: trouble codes

Hi Sandra!
The trouble codes listed are defined as:

P0141 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

P0300 Random/Multiple Cylinder Misfire Detected

P0331 Knock Sensor 2 Circuit Range/Performance (Bank 2)

PO300 & PO331 are possibly symptomatic of issues caused by PO141, which would have a direct influence on the air/fuel mxture... which could cause missing and knocking.

So the first thing I would try is replacing the Bank 2 Oxygen Sensor, after making sure the wiring and connections to that sensor are in good shape.

Does the engine show any physical issues such as loosing coolant, smoking exhaust, overheating? A blown or leaking head gasket on the #2 bank could also present these (among other)
codes.

Good luck and let me know how it goes!

I would start with the Mass Air Flow sensor.  It is located on the air intake line just after the air filter on the way to the engine.  You can take the lines off both sides of it and spray it out with carb cleaner.  You will have to clear the codes after that.  If that doesn't fix it you might have to replace the Mass Air flow Sensor.  Hope this helps.

P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.

P2106 is an informational code and is usually set by some other fault.

This DTC means is that the PCM detected a fault with the electronic throttle control and went into fail safe mode. It doesn't tell you specifically what system or component went haywire, just that something was wrong, the PCM didn't know what to do so it went to a known good operating parameter, in this case fail safe mode. Likely is a problem with the TPS sensor and will need to be replaced.

Hope this helps.

How to fix code po300 on 02 explorer ?


Well thats a tough one. Code 300 means you have a random miss and its not bad enough yet to pick a cylinder.
You could replace the spark plugs, but until it gets bad enough to set a code for just one cylinder it will be tough to find the actual problem.

1996 olds cutlas supreme, 3.1 L has trouble codes PO171 and PO300. Any Ideas?


The po300 is a misfire code.This means there is probably a plug,plug wire,ignition coil,or ignition module.Check the coil towers one at a time.These are know for corroding.If you find one that is corroded then replace the plug wire also.Po171 is a lean condition code.The po300 could be causing the po171.If you have not had a tune up Now would be a good time.Hope this helps.Good luck.

Code po300 check engine light


The Po300 is a random misfire code where the PCM is picking up the misfires. The other two codes are lean mixture codes. More than likely these are due to bad intake manifold gaskets allowing unmetered air to enter the engine causing the engine to lean out and possibly run a little rough when cold

I have a diagnostic trouble codes p1768,po300,and a po420. what does this mean?


I have tow of the three requested codes. po300 is misfire detected at multiple cylinders. See po301-306 represent the cylinder # misfire. So 301 is cylinder #1 misfire.

po420 is Catalytic Converter Efficiency Failure
