What is the solution to a Code 22 on 93 civic ex coupe d16z6 ??

 

I don't know much about Hondas since I'm looking to buy one, but a search showed code 22 as "VTEC pressure valve." You need a certain oil pressure for VTEC to engage, so first make sure you have enough oil in your engine. If your oil is low, add oil to the line and your light should go off. If your oil is fine, test your oil pressure with a gauge (I'm new to Hondas so I don't know where you would attach a gauge). If your pressure is low then my guess is the oil pump is either bad or you've got a dirty pickup for the pump. If your pressure is fine then you probably have a wiring issue with the sensor itself and you should use a voltmeter to test the sensor and the wiring. My personal guess is a wiring issue, but I'm a Ford guy so I don't know.

 

Thanks for your input i really appreciate it !!

 

It's entirely possible to have a dent in the oil pan that is preventing sufficient oil pressure to the vtec pressure switch.
