VTEC Solenoid Valve code 21
my PR3 ecu is throwing 21. VTEC solenoid valve. My question is why? My VTEC still kicks in at the crossover point.
Could anyone tell me where the solenoid valve is located?
and has anyone else had this problem and figured it out?
TIA

Re: VTEC Solenoid Valve code 21 (incubus)
Do you have an oil pressure sensor?
if not then that might be the problem,
im pretty sure that your ecu is looking for the sensor and you dont have it wired up, though I could be wrong.
