I know there is info everywhere, but I cant seeme to find all the info I'm looking for. I am finding all h22 but thats not what i need.

I bought a 96 accord LX Auto(non vtec) with an f22b1 vtec motor. The vtec is NOT wired or working. (The car might be in limp mode, not sure. This is my first honda.)
Anyway, I bought the P0H ECU. I had to replace all the wiring under the dash because it was burnt and melted. I did NOT get the engine wiring harness.

When I get up to vtec kick in point it doesnt shift, I have to let off for it to shift.

I have read that I need to wire the vtec solenoid and oil pressure switch. My motor does NOT have the oil pressure switch, there is a bolt in it. I checked the junkyard and they are the same. I am not able to buy the switch at the parts store.

Does the oil pressure switch have to be wired? Where can I buy one? Does anyone have the ecu pinout with wire colors for the 96/97 obd2? Help me please. I'm getting a vtec malfunction code with the CEL and I need to get the car inspected this week and the CEL can't be on. thanks

 

bump. Still needing this info. Thanks

 

i am having the exact problem and am nearly there with the answers but still dont have the pin up yet. i was told to google 2.2 v-tec obd2 pinout and there you should find what you looking for im still stuck if you have any luck please help me thanks

 

Search...I've seen this discussed here several times....heck it might actually be in the FAQ.

lol nice link^^^

The OBD2 F22B1 VTEC does not have a pressure switch. It only has the VTEC solenoid, that is why there is a bolt where the PSW usually is. The VTEC solenoid is wired to Pin A8 of the VTEC ECU. The other wire of the solenoid goes to chassis ground.

OBD2 Connectors, view from wire side


Wire colours around the VTEC pin;
A1 is YEL
A2 is BLU
A3 is RED
A4 is BRN
A5 is ORG/BLU or ORG/BLK
A6 is ORG/BLK
A7 is empty
A8 is GRN/YEL VTEC Solenoid............
A9 is BRN/BLK

However if you are adding VTEC to a non VTEC Accord. I don't think the GRN/YEL VTEC wire will be in the ECU wire harness.... Unless you replaced it.

 

hey i have all ready did this swap, i was able to buy my motor with harnes it all bolted striat up with my f22b2 auto trans, the harnes pluged up just fine and i had found the right ecu i just had to run a wire from the ecu to my harnes for the vetec and im proud to say iv had it up to 130mph

 

hi i have a 97 accord ex and there is a male connector on the oil pressure senesor (i think that is what it is called) that screws onto the the vtec solenoid but i can not find the wiring to plug into it. the plug that is missing is green. my car is putting out p1253 engine code. wanted to know if anyone knows where the wires start from so i can run new wires and if that is the reason for the engine code.

 

Help i need a engine harness diagram for a f22b1vtec i recently bought a f22b2 harness but idk were connectors go oh. Yea almost forgot da wiring to da dizzy obd1
