I have a 94 OBD I JDM H22 going into a 98 OBD II Prelude. I only have the JDM motor right now, I dont have an OBD II motor to take things off of. I need to know where I can buy these OBD II sensors that I need.

What? You need the timing and balancer belt crank sprockets since they have makers for the TDC and CKP sensor. If you don't have the markers on the t-belt sprocket, the car WILL NOT START (no spark). If you use the wrong balancer belt sprocket, you'll throw a CEL 4 code. I know this from first hand experience.

Look at the TDC sensor on the left which reads off the back plate of the t-belt sprocket which is one piece). The CKP sensor on the right reads the b-belt sprocket...


This is a JDM one... note, no markers for the TDC sensor to read...


JDM b-belt crank sprocket on the right and USDM/OBD2 b-belt crank sprocket... see the amount of spokes that the CKP sensor reads? You'll throw a code and can't rev past 3500 rpm...


You are correct with knock sensor but it isn't all that hard to change once the motor is in (I've done that too). Or, if you are kind of lazy, you can cut the single signal wire and solder the JDM connector on... I have pics of that too if you want.

Keith, my bad. Late night, wasn't thinking. It left my mind that the markers were on the crank gear and balance shaft gear. Thanks for the correction.

What happened to the motor in the car?As far as where to buy the parts junk yard possibly if you want to go cheap, dealer would be the best bet. Switching to obd1 may be easier for you.

Installing a skunk2 to OBD2 to OBD1 harness and p13 should pass inspection, Honestly I dont see why it would even be looked at in the first place by an state inspector. Also should pass emmissions I dont see why not . As long as you wire everything up correctly had have no check engine lights on.

Good post. I need to convert my 00 civic (95 h22) to OBD2 for emissions as well. The sniffer test isn't the problem, it's the fact that an OBD1 ecu will not scan with their ODB scanner. The ECU HAS to be OBD2.

Of course, that is for OR emissions, every state will be different.

Do you still have your old H22A4 from your 98 motor? Everything you need to swap over to use OBD2 should be on your old motor.

No thats the problem, Ialready shipped the motor out. I dont have and junk yards around here (Buffalo NY) that carry anything for the prelude. Where can i get the stuff I need, used. I know That I could probably go to honda but they are super expensive as Im sure we have all found out 1 time or another. Anyone got an extra H22A4 layin around that would sell me the parts I need.

I think I have an A4 left I'll check and see if it has the crank sensor on it. Do you need injectors, fuel rail all that good stuff?

I think I might have an extra CKP and TDC sensor as well... but you would still be missing the oil pump housing, t-belt and b-belt crank sprocket still.

here's a thought, how about you try to use a obd2 to obd1 conversion harness to do the swap, instead of switching the sensors

If im not mistaken, he has to keep his car obd2 because of emissions. I know here in arizona, on obd2 equipped vehicles, they hook the car up through the diagnostic port (on my car its under the center console cup holder) and if your storing any codes, or something isnt right with the computer, sensors, etc. you wont pass. And if you have an obd1 ecu in your car, they wont be able to read it.

Im getting ready to swap in a jdm h22, and came across this thread. Thanks too all who posted the stuff needed to stay obd2, its really gonna help me !

I would say yes.... If you plan to use an obd2 ecu.

Because regardless if you are or are not using the balancer shafts, the sensor is still required in order for the ecu to work properly. And since the sensor runs off of that gear, you must have it.

Which sprocket are you referring to? The one of the crank? If so, then yes, you do since the CKP sensor reads off that.

From what I've read, this thread is about staying or converting to OBD2. I'm wondering if the same rules apply when switching OBD2 motor to an OBD1 ecu applies such as changing the oil pump housing, sensors, etc...? I have a H22A4 going into an EK which are both OBD2's but want to go OBD1. Couldn't I just use the conversion harness OBD2&gt;OBD1 and call it a day??

Yes, but would that be cool in "CalEPORNeyeA"? Dropping an EK (OBD2) to OBD1 isn't going to fly with the smog refs.
