leaky CPS..

[MaXimaSE]

ok, so I think I have a leaky CPS. I can see oil hanging out around its general location and behind the pulley assembly on the black cover, and where the CPS is located in the side of the motor. I tried using my multimeter to get a reading on this, and the MAF. I couldn't pickup a reading on either, I guess I couldn't get a good enough connection??

I tried testing the resistance/voltage on them but I don't know If my multimeter was set properly.

What size O-ring fits the CPS.. Im going to try replacing the O Ring on it, and see if that fixes the leak. I don't think It's the black cover behind the pulley assembly that is leaking. It starts right below the CPS.
