My car give my check engine code 22. That's mean the VTEC Oil Pressure Switch (1.8L GSR). What do I have to do? Change it or is there somenthing else that I can do??Do you know where to find this switch??Help me please.

 

It's the little switch that's bolted to the VTEC solenoid. Take the solenoid off and remove the switch and clean out the whole thing. I'd replace the gasket, too, if it's haggard. Make sure it's clean and dry (if you use solvent- don't know if it can be used on the solenoid without being harmful) before you reinstall.
