P0300 is a random misfire code. I dont have a listing for a P0200 code. Are you sure that is the right code.

Po200 and po300 codes


in my DTC book p0200 is a Injector circuit malfunction and p0300 is a Random/Multiple Cylinder misfire so I would check wiring for both and maybe change plugs an wires I think you have broke wire that is shorting out so I would try to clear the codes either with a code reader or by disconnecting the battery for like 15 min and see if/how long it takes to code again after you get the injector wiring checked

My 2004 gmc sierra detected a PO200 and PO300 code..what does that mean and how can i handle the problem?


po200 is a injector circuit issue. the 300 is most likely related to it.. There is a good chance you have a PCM issue that needs to be looked at. No way to tell whats going on without diagnosing . This will leave you stranded if you don't deal with it soon

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!
