vtec solenoid differences from h22a h22a5

You need to tighten the VTEC solenoid bolts to 12Nm / 9lb/ft which is fook all.

If you have both have a look and see if there is any difference.

Have had a lil goose at h22a5 solenoid and it dosent have the green connector on the front. Can i take h22a one of some how? Need a little bit of a how to guide on how to work out mechanical fault or electrical? Sorry for the nubey post. What would you guys do if you were me.

Here are some pic I have taken of my VTEC solenoids:

H22a with a snapped pressure sensor I need to replace

H22a2

H22a7

H22a8 which does not have the the same sensor but does have a blanking bolt.

All look exactly the same to me?

What's the differences?

Overtightening could actually cause leaks (damage / overly aquash the seal on a point load, or cause the casing to distort and not give even pressure all over the seal)

The H22a8 dos not have the same green oil pressure sensor but does have a blanking bolt. He should be able to remove the pressure sensor from his H22a and put it on the VTEC solenoid from the H22a5. It wont make any difference if it is the pressure sensor that is goosed (but it isnt giving any codes).

Does your CEL come on with your keys at position I and go out when the engine is started?

All lights go out when engine starts other than that cat light lol

Vtec is working again but dont know for how long. Need to get this car sorted but time is allways against me
