Are being thrown on my car. I had a B16A2 in the car, motor mount failed and I ended up putting a B16A block back in, nothing has changed other wise.

Vtec engaged fine before the swap of the bottom ends, I took apart the solenoid cleaned the screens, Oil is at the appropriate level, Connections are fine and I am stumped.

The only difference in actual performance of said vehicle is that Vtec will not engage and my Redline is now 6500 instead of the regular 8 or 8200, I forget what it is.

It was suggested that my Vtec solenoid and pressure switch plugs were mixed up, but I cannot seem to find a picture to help me look for that problem.....

Other then that everything else seems fine, but I am just stumped and I could use some help.



Car: 1993 CX

Motor: Stock B16A

ECU: P72

 

halp

 

your vtec solenoid plug and pressure switch plug can't be mixed up with one another.. they have 2 totally different plugs.. but it sounds like you have a wire that is messed up somewhere.. What year is your car?? is it a 92-95 or 96-00??

 

92-95

found 2 plugs that might be swapped around, disconnected the battery about 5 mins ago, gonna eat some grub, hook it back up and see what happens.

 

ever find out if that was it??

 

I got it down to the oil pressure switch, gonna try the paper clip trick with the ecu and see what happens

 

cool, if it is the Vtec Oil Pressure Switch, then there is a bypass you can do to where you don't have to get another one to put in it... I have a diagram I can give you if you need it....
