I am throwing a code 21 and 22. I know why I am throwing code 22 cuz I have a dented up oil pan. But I don't really understand what code 21 is, after researching that didn't help much. So what is it?? Does it mean the vtec solenoid is faulty?? How do you fix it?? Could it be caused to flash cuz my temperature gauge is not working and vtec only works when the temperature is at normal.

21 and 22 are vtec sol, and vtec pressure switch......try taking it off and cleaning it, and making sure the screen isn't plugged up...if that's fine make sure the wires are all good, and if that's fine.....get a new sol. :-P

so do you mean the code 22 isn't because of the dented up oil pan?? But something else, ill try the processes you said too to claify the problem.

no, the dented oil pan will not affect the Vtec pressure switch
