2002 Civic 1.7 L – I keep getting P1259 code. When I look it up it says V-tec. Dealer wants $590 for the new spool valve this thing is so old I’m not doing that. I did a clean and inspect of the spool valve and the solenoid ohms out as good. Re-installed. The first pull it felt strong like it hit V-tec but threw the code again. Replaced with China-special spool valve same deal pulled good and throws code. Question: Is 0W-20 Royal Purple too thin for the V-tec to work right? Do you think it’s probably the Pressure Switch that’s bad on my original spool valve? I’m at a loss but I know the Honda knowledge is out there thanks for any help in advance guys. I’m 57 years old.
