Don't know the code.

The problem turned out to be that an oil line, which supplies pressure that triggers the operation of the vTec solenoid, has a little filter screen which was clogged. They rinsed it out, put it back, and the car runs fine now.

No charge for the second visit. Of course, I'll never know if it was really a failed vtec solenoid, or just a clogged oil screen in the line in the first place.

Where do users of this website get these codes? I don't have diagnostic equipment. Will the Nav screen or the radio/clock display show the codes somehow or other. Hate to reveal my ignorance.
