hey i pulled up my cel 2day and i found that it says the VTEC Oil Pressure Switch, i went to see and the switch is in place?? so does this mean the switch went bad??? also i have number 23 also which is the knock sensor, could the knock sensor cause cel number #22 also thankx.

 

For the code 22 make sure you have enough oil in it. Code 23 I d say pull the sensor get a DVOM and the test it by putting one probe on the pin and the other on the sensor houseing, then tap it gently on a table or have a friend do it with a hammer-GENTLY- you should be able to see the ohms change every time it is hit.
