Got a code 22 oil pressure switch today. It eventually went away and did not come back on but what the hell....does that sound like it needs to be replaced?? Sometimes the oil light will come on for a min. or 2 and then go away and not come on the rest of the day. What would you all suggest doing? Today was the first time the CEL came on for that code. The engine is rebuilt by me with just over 1,000 miles on it. BTW b16 vtec switch

 

slow night

 

The code was two long flashes and two short flashes? If so check over the wiring, should be a black and blue wire, that was where i ran into a problem, poor wiring.

 

its not in the wiring

 

check ur oil level..also check the connection of the plug....there is a chance that it is kinda loose and at a high rpm when there was a lot of vibration in the motor bay it might have temporarily disconnected and caused u to throw a code...also ground it to the chassis...

 

oil is perfect this engine on has 1,000 miles on it. I will try grounding to the chasis

 

I had the exact same problem and I grounded it to the chassis and it wnet away. I had no idea where it was supposed to be gounded so I guess I lucked out.

 

its ususally grounded under a screw on the solenoid..this is not the best way..ground it to any spot on the chassis and u should be good to go
