So I swapped a 1996 F22b1 into my 1997 Accord EX that came stock with a F22b1 many moons ago.

I am getting a code 22 for vtec pressure switch. When I went to investigate further i found that it appears the pressure switch does not exist. There is a place for it on the vtec solenoid housing, but there is just a bolt in it.

I used the wiring harness that came with the engine.

Everything I see online says this is where the vtec pressure should be.

Can anyone tell me if its located somewhere else? There is no oil pressure sensor on the back of the engine.

Also what wire colors should the two wires be?

Here is a picture.

 

i got some pics coming your way.

already know your missing the switch sensor where that bolt is plpugged in

 

Yeah I know what its "supposed" to look like. But I dont see a connector for it in this location and the bolt looks factory.

 

i also have personal pictures of my vtec assembly if this manual doesnt qwork for you.

the wires going to the pressure switch are blue/black and the plug is green like the one that plpugs into your temp switch A

 

to be honest i believe the 98-02 vtec assemblies had that spot factory plugged.

someone may have replaced it with a 6th gen vtec assembly.

 

So the green plug with blu/blk and brwn/blk wires does not seem to exist on the harness. At least not in that area.

If it did I could just take the sending unit off one of my junk engines/harnesses, but since its not even on the harness.

 

did you get this harness with the engine at the junk yard?

man you are not having any good luck with this car as of late.

 

Yeah it came with the engine. I will look into it further tomorrow since I have the day off. But I quickly looked it over tonight and it doesnt seem like it was modified in anyway. There is a spare green plug on the harness, but those are not the colors. (I have a lot of spare plugs since I dont have AC, PS, CC, EGR, etc etc)
