Why does my 2004 honda accord 4 cylinder-emission control light comes on and then goes off after a couple of days. Seems to be related to getting more gas and also seems to be related to amount of gas I have in tank. About 1/2 full the tank the light comes on and then goes off eventually, after I fill up.

The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.

it might have a bad coil pack. does it miss at all? the plastic boots deteriate and cause an arcing in the spark plug tube. my experiences have always been high rpm is ignition be it a coil pack or something in ignition.

I had the same problem. My battery was going bad. When I replaced it with a new one, the fuel gauge worked fine.

2003 and up Honda Accord with 4 cylinder engines do indeed have a chain and the V6 has a belt which must be replaced at 110,000 miles. Why? Ask Honda, they designed the engines.

the float sensor attahced to your fuel pump sounds as though it is not working properly. Usually this occurs when the car rides on E many times and becomes damaged. depending on the model it may be necessary to replaced the sensor assembly or if it is the complete unit the whole fuel pump.

Also, depending on your driving habits your car can use more gas if your are driving in traffic (stop and go). Average out your fuel mileage by filling up a few times and keeping a log of the gas consumed. Do this by reseting the trip meter when you fill up and when you fill up again divide the total mileage on your trip meter by the amount of gas you used by getting the amount of gallons it took to fill up again. ex. 360miles divided by 10gals = 36 miles per gallon.

note. make sure you check your air filter (is it clean?) and tire pressure (32psi) these can be contributing factors to poor gas mileage
