my check engine light came and spit out a code that was P1259 which i looked up and said that it has to deal with the vtec mal.. i have heard some things about an oil pressure switch and i might need to scrape off the sludge. can anyone tell me where the switch is located and how would i go about doing this? or any other suggestions to what is wrong.

i jus searched a little more and now i found that the code means Immobiliser to PCM signal error

 

If you clear the code does it come back or not? if it does the vtec oil pressure switch is a 2 wire usually green plug that is near the exhaust cam end cap. on the distributor end of the motor.
