help!! please 06 frontier po300 and p051 po1168
Hi Guys
I have an 06 frontier with 89k miles on it. started having problems with it about a week and a half ago. the check engine light came on and had the p0463 fuel level circuit input high. yes the gas gauge was not reading the fuel level right, saw that there was a recall notice to correct, figure would get it fix later. towed my dump trailer around alittle and the truck started to loosing power on the highway. rechecked the codes and found p1168 fuel air metering control, p0051 a/f sensor 1 heater bank 2, p0300 random misfire. replace the a/f sensor on the driverside. checked the sparkplugs they where fine but replace anyway with new plugs. cleared codes and away i went. But still the truck did not run right , at lower speeds rpm everything seemed fine but when i got onthe highway the truck would not go. like something was holding it back. just seemed to get worse every time i took it on the highway. almost felt like the cat was plugging up. then the check engine light came back on p0300 random misfires if i took the rpms about 2500rpm. truck has no power bog down can't go over 35 with out alot bs noise comming out of the engine. Spark plugs seem fine and the coils test fine. I can't even drive it now the codes are p0300 and p0463 only right now. could it be that IPDM recall ECM relay? I'am located in central Mass. and the dealer near me won't help. oh yea I replace the maf sensor , cleaned the body grounds around the bat and air filter as per the manual. how do I check the cats? smells real rich right now Please help Thanks CJ |

The p0300 code is affiliated with the spark plugs and the AF sensor you just changed. I'd start there. P0463 is the fuel tank level sensor - change it

the a/f was replaced and the plugs. all of the coil test out fine
fuel level sensor i know needs replacing right now after a little more research, i think it's my Cat. planning on removing the o2 sensors to see if the cat is all broken up or plugged read alot of the nissan Cat break up into little peices early in the life cycle i hope thats it and nissan will cover the cost |

Apparently you want it to be a cat problem huh.
You need to get a AF and o2 sensor reading of "live data" with the condition present and compare the two sides. This will tell you if the catalyst is working or not. FYI- My original response back to you was for you the recheck the plugs you just put in to make sure they were in fact not misfiring |

I suspect the P0300 is caused by not having proper fuel flow. So take care of P0463 first.

He hasn't had any activity on the site in 6-years, so you likely won't hear from him. I would suggest you start a new thread about your vehicle and give a little more information as to exactly what's going on. Good luck!
