i have a 2003 accord that has lots of problems. one of them is it burns oil like crazy. i dont know what it is. i change the oil every 3000 miles. my car does have a check engine light but the code is p2646 and i think that jus deals with the vtec. so does any one know what could be wrong with my car?

 

P2646: VTEC Oil Pressure Switch Circuit Low Voltage
The first thing the service manual says to test is the VTEC Oil pressure switch itself. I would check to see if it is leaking.
