Okay so I blew the stock f22b2 out of my 97 accord and I went and naught one from a jdm place in Scarborough the engine is an f22b. My f22b2 had a crank shaft positioning sencer down by the belts so there is a plug on the harness that plugs into it, I put the f22b in and it has no wire for that plug . Later I learned it does it through the distributor that came with it but I didn't put it on cuz the one plug didn't fit into my engine harness , what do I have to do? I'm lost can I get any adapters or anything let me know ASAP thanks guys

 

Easiest thing to do would be to make sure your old engines oil pump is fine and install it on your 'new' engine. This would make it plug & play.

 

Ok I have heard about the oil pump but what does that do ?

 

It allows you to run your original OBD2 TDC and CKP sensors along with the associated pulleys. The OBD1 oil pump housing does not have the mounts for the sensors nor do the pulleys have the toothed wheels like the OBD2 ones do!

Here is a picture of the OBD2 oil pump housing with the two sensors mounted to it. TDC sensor is on the left facing right and the CKP sensor is on the right facing out. This image also shows the 2 toothed timing belt pulley, it is the TDC sensor trigger wheel.



Here is a picture of the OBD2 12 tooth balance shaft belt pulley, that is the CKP sensor trigger wheel.

 

I got a dumb question. If the cylinder fires every second rotation, how does the ECU know which to fire when the engine is first started up? On a camshaft driven sensor, no problem, but the oil pump is driven by the crank, right?

 

Most JDM engines don't have crank sensor so for 97 up Accord F22B engine you will have to replace with a new oil pump and put crank sensor on it as JDM engine oil pump doesn't have the hole for crank sensor.

 

doesn't matter if they are mounted on the crank or the cam, it's the number and location of the teeth on the trigger wheel, in conjunction with the engines orientation, that determines when the ECU & ignitor fire each cylinder. for every ration of the camshaft the crankshaft rotates twice. So you just divide the number of teeth on a crank mounted sensor by 2 to get the same result.

For example,

OBD1 Accord

Camshaft mounted sensors (distributor)
CYP = 1 tooth
TDC = 4 teeth
CKP = 24 teeth

OBD2 Accord

Camshaft mounted (distributor)
CYP = 1 tooth

Crankshaft mounted (oil pump housing)
TDC = 2 teeth
CKP = 12 teeth

These two setups send exactly the same signals to the ECU!

If you want to get into even more specifics;
The CKP Sensor determines timing for fuel injection and ignition of each cylinder, it also detects engine speed.
The TDC Sensor determines ignition timing at start-up (cranking) and when crank angle is abnormal.
The CYP Sensor detects the position of No.1 cylinder for sequential fuel injection of each cylinder.

 

Ok, I was thinking that there was no distributor sensor on OBD2.

 

Damn, I just did an engine swap exactly like this. I swapped EVERYTHING except that damn pulley. That could explain why I have no spark. I've been troubleshooting my "no spark" for 1 week now. Damn it. It now makes so much sense. I've done everything I could think of.

 

Can anyone help me? There are 3 pulleys down by the crank.

I'm ordering 16 and 17. Do I need them both?

This is what happened. Timing belt broke. Bought a JDM motor. Stripped it down to just the head and block, even removed oil pump housing since it doesn't have holes for bolts to mount the 2 sensors. I know one is crankshaft, not sure of other. Anyways, I used the JDM pulley, which seems to have a different amount of teeth. I going to buy the correct pulley since I threw my obd II or American 2.2L pulley away. I'm doing this because I have no spark. Tried everything else, why not this.

So, back to my question. Which pulley is used for those sensors? 16? 17? Or both?
Thanks

 

Chec/k the backside of your JDM balance shaft sprocket.
Does it have the same outer ring tabs on it like...


If not you will need to purchase it.

If there are some yardes near you, you can always see what they want for the same pulleys. I would not be surprised if the 98-02 F23 used the same sprockets as the 96/97 cars.

 

So, this pulley clearly goes to the sensor with the blue wire and the white wire. I believe it's the crankshaft pulley. What is the sensor with the red green wires and looks at the smaller pulley. Picture coming.

Thank you for the help so far.

 

Would anyone recommend or not recommend after market sensors from eBay for 12.00? I'm thinking about replacing them since I'm already down here.

 

Changed the pulley, got fire! Car runs great. First engine change is a success!

 

Just bought a JDM having the same issue. My old engine leaked bad out the timing cover, it's a 97 wagon. The engine I bought doesn't have a sensor harness. Can you get just the seals for the oil pump housing? I'll have the engine out in a few days, covered up with transmission work at the moment.

 

I bought a timing belt kit and gaskets for an oil pan. Every seal and gasket came with what I ordered. I got everything from rockauto.

 

Thanks!

Got everything ordered and some new axles too.

 

So if the F22B DOHC has the sensors in the distributor, do you just run the wires that were on the side of the block to the distrubutor plug and splice them in? What do you do with the internal DOHC coil vs the external F22B2 coil? Does the check engine light stay on all the time since I want mine to pass emissions with out help? I have read that the F22B DOHC OBD2 doesnt't have an EGR, is that true and how do you deal with that with the ECU?

 

Mine is SOHC. Both have EGR but connector is different. I used my old EGR. The cam/crank sensors on my old engine were on the oil pump housing, JDM engine had them in distributor. I bought a new oil pump, mounted my sensors on the pump and used the old distributor. Went with new timing belts and tensioners. It runs great. I have some pics of the build in my gallery. Got a auto trans coming from JDM Quality in Canada. I highly recommend them, I bought the engine from them too.
