Stoopid Check Engine Light

[Spaz]

So, the ECU spit out these codes to me

0705 EVAP control sys
0903 EVAP canister vent control valve
0304 Knock Sensor

Has anyone ever gotten these codes and had to replace them? Get them Replaced? Can anyone tell me about the cost it'll take to repair the stuff?

Thanks for the help

Look behind the drivers side rear wheel. The Evap system is located under there. You'll see the canister and the valve. The valve gets contaminated by crud the rear wheel throws up. You can take the valve out and clean it up with WD-40 to get it functional again. The valve is the unit with the electrical connection on it.

Once you get the valve working, clear the error codes and see if your KS code comes back. The KS code means your getting a signal from your KS sensor thats out of the acceptable range. It does not necessaraly mean the KS is bad, it could be indicating you have excessive ping and knock. Make sure your car is running correctly before you waste money on a new KS sensor.

And if that's the case, try investing in better fuel. Maximas are supposed to run on 91, minimum.
