How to fix VTEC System Malfunction code P1259

SOURCE: just got a P1259 code on my 98 honda accord

I have a 1998 Honda Accord EX. I had the check engine light come on as well and I had the code read by PepBoys. The code was:P1259 or VTEC SYSTEM Malfunction.
I Don't know jack about were to start to fix this problem, so I bit the bullet and took the car to my Honda Dealer. The problem was checked out and was told this.
( REPLACE VTEC VALVE ASSEMBLY)
I had them do the work because I dont know how to do this. So after $204.00 in Labor and $162.29 in parts, for a grand total $366.29, The car was fixed!!!!!!! Run's great and no check engine light on anymore. So to help you out as best I can, here is the numbers that are on my work sheet. I dont know witch numbers represent the part number but this is how it looks on my paper.

1 15810-PAA-A02 8108797-90870 VALVE ASSY, SPOOL $150.75

1 15825-P0A-015 8161598-15999 FILTER, SPOOL VALVE $11.54

There you go! I hope this gives everyone a place to start. maybe get your self a Haynes Repair Manual (#42014 is for the 1998-2002 Honda Accord, all models) and try to do the work your self. Good luck to all of you form Donald M. in SoCal.

P1259 Immobilizer to PCM Signal Error,, ok, first does the car hic up at around 4000 rpm'? what you have here is possibly 2 things with a honda, and that code just happens to pop up for both,, One, change the oil, and 2, you may need to change the Vtec pressure sensor/screen (solenoid),, its located between the Vtec solenoid and the head,, My guess is that your oil is pretty bad, or you just had an oil change, either way ,, clean that sensor,, it may or may not work, if not, you'll have to replace it
