Well I just got my JDM H22 in my 93 Accord. I'm getting a CEL 22 code which is the VTEC oil pressure switch. Now I have heard that the switch does not come with the JDM motors so I am assuming that HMO sent me a USDM p13 ecu. Now.....I was planning on getting a chipped p28 ecu in the near future. Would this solve my problem? I don't want to waste 70 buck on a new switch which is the size of my thumb when I can just go out and get a chipped p28 that doest look for it. Can any one confirm that the chipped p28 doesnt look for it, or that the option can be disabled to look for it. I'm either going to be going with uberdata or hondata.

Thanks!

 

JDM or no JDM... you have a pressure switch.

 

Nah mine doesnt have it...see.

 

motor specs...?

 

i'm having the same problem in my 96 accord with 91 to 93 jdm engine (don't know certain year) it's throwin the same code 22 for mines also i thought it is the ecu but i'm not for sure??? Yes i do have a oil pressure switch the only ones that i know that doesn't have one is the f22b1 engine it only has a vtec solinoid. and yes i done the odb2 to obd1 conversion.

 

o yea by the way will this stop the engine to rev to 7200 because it only revs to 6500 with the p13 ecu

 

the reason its only reving to 6500 is because its in limp mode...because its not seeing the vtec oil pressure switch

wrong. every honda vtec motor uses both sensors

 

are u sure because i didn't see one on the f22 when i did the swap

 

so what plug on the harness from the f22 fits on the h22's pressure switch???

wrong, some didnt. mine doesnt. his didnt come with one either. im not sure what it was that distinguished between ones that did or didnt, but some dont.

 

and will it still be in limp mode if the knock sensor is not wired up??

 

if your ECU checks for it (P13?) then yes, absolutely.

 

cpmike!

 

oooooookkk

what?!? maybe because someone stuck a bolt in there...

it may be related to the chassis the motor came from, or based on the ECU that ran it, but im not sure.

 

yeah I know atleast 4 or 5 accords that did the H swap that have the same problem with that bolt in place of the switch.

You definitly need a Haynes manual for both the prelude, and the accord. That will tell you exactly where on the harness each plug is, and where it goes to.

this is the best right up on 5th gen accords i have ever run across, it tells you where what wires go and what plugs to use, and it matches up with what i had to do on my first H22 swap, im in the middle of a second.

alot of people take the prelude harness, and clip good leads on the wires so that you dont have to splice each wire twice on the plugs that need lengthening.
this is a pain, but its alot better than most of the civic swaps!!!
Good luck to ya

correct me if i'm wrong but didn't the plug on the f22 harness have have no plug for the vtec pressure switch??? I think it only came on the h22 harness (for some of them)

 

???

 

Mine didnt have the switch either so I just bought one.

 

to cure the problem here is what you must do;

1) purchase a vtec pressure switch.. (I have a spair that works great for cheap if you want)

2)take the bolt out.. install the presssure switch on the motor

3) run a wire from D6 on the ecu to the switch and ground the switch under the hood

4) drive around with vtec

PS.. there a only a few codes that will limp mode your car and cause the 6500RPM redline.. those being anything vtec.. pressure switch or soleniod.. as well as vehicle speed sensor.. and I think there is one more but I can not remember..
KNOCK will not cause limp mode! nor will no IAB.. these are most common with the swap Also if you throw an 02 code you will not get limp mode either..

consult for more info;

Good luck and this is 100% for sure how you correct the problem

 

thanks!!!!

 

need pinout locations for obd1 p13 please
