P1259 Still dont work!

Question

So i have a code on my 2000 civic EX. Swapped out 2 vtec solenoids and 2 oil pressure switches. 1 was brand spankin new. Drivin through 2 oil changes (approximately 1800 miles) still throwing code p1259.

Answer 1

You would need to test for power on one side of the VTEC and go as far as swapping the PCM with a known good working one. If the VTEC is good and so is the switch this leaves  you with a circuit problem .
