HOT oil should be 10-20psi at idle (around 800rpm)
and quickly jump to 40ish above 1500rpm
and then hit a solid 60-80ish above 2500rpm and stay there till redline.
these are readings to expect from a healthy engine - which is what yours sounds like...
Dxs - what do you mean by "i will get an aftermarket" one?
i meant an aftermarket oil pressure gauge..
i doubt i will now.. too poor
looking at getting a 2nd hand switch and seeing how i go
oh, and the answer to your original post (which i think needs to be answered) is that the wire from your semnsor to teh ECU might be cut/disconnected due to the VTEC controller...
what sort of ECU is yours? look at the code is it PR3 or PW0?
thanks tinkerbell.. ur a champ
i believe EF8's are all PR3
the thing is that vtec has worked a couple of times without the engine light coming on.. so i am hoping it is a faulty switch.. i cant see any cut wires in the bay itself.. although it does look like some of the stock cable ties for the wires have cracked etc, which gets me thinking if the cables have been tampered with, but i doubt it.. might check the ecu cables now to see if they are fine.. but they looked fine if i recall correctly
i am trying to source a b16a1 pressure switch and setup off a member of this forum.. we will see how that goes
edit: just checked the ecu.. has a serial numbers of XXXXX-PW0-XXXXX
so it is a pw0 then
check you have continuity between B5 on the ECU and the pressure switch connector... (middle black plug, blue wire with black stripe)
if continuity exists, it must be a faulty sensor OR you have low oil pressure.
thanks tinkerbell i did inspect the ecu plugs and they all seemed fine (as in i could not see any that looked like they had been cut etc..
The vtec controller i had was a spoon one, as mentioned in my first post.. these have kinda middle man plugs, ie the controller plugs into the ecu and the original plugs plug into the controller.. hence u dont have to cut any ecu wires etc like other controllers for it to work.. simple plug and play application..
anyway i just payed for a pressure switch and the rest of the 'assembly' (i presume solenoid etc etc) off a XSI integra.. so hopefully i will have a tinker and see what happens
Just thought i would update this thread just incase someone uses it as reference in the future and wants to know the conclusion.
Basically i recieved a vtec assembly a couple weeks back which is the solenoid and the pressure switch etc etc, the things that control vtec that are bolted to the head.
Basically undid the 3 bolts attaching the old one, cleaned the replacement one up a bit with some carb cleaner.. and bolted the new one on..
the one that was already on there also had some gasket sealant on the gasket that joined it to the head, so it looks like someone has removed it before..
anyway bolted on the replacement, also check all the holes on the head that allowed the oil to flow to the assembly.. warmed the car up got some fuel and took it for a spin.. got into vtec a good 5 or so times no worries.
so inconclusion i would say my old vtec pressure switch had something faulty with it..
:)
Fantastic. Good to hear you got it sorted. How much did that gear set you back? Brand new or used?
Thanks
Jase
got the assembly 2nd hand off spardakis (sp?) from these forums.. 80 bucks delivered
i am sure honda would have wanted a packet for it new.. but such items should be found fairly cheaply seeming though there are a lot of B series engines in pieces all over the joint.
:)
a bit of a late reply, but i'm glad to see you got everything sorted, and at an excellent price too!!! I have the same problem, so i ordered the pressure sensor and solenoid through a member of these forums, which worked out considerably cheaper compared to the ~$450 my local honda dealer wanted :thumbdwn:Quote:
