Ok, I have run into a little problem. After I pulled the Pulley off from the B18B to swap some stuff, I notice that the Timing Gear that's behind the pulley has these gears that stick out with a SENSOR that I guess reads RPM or something?


When I pulled the crank pulley off of the B20B, the timing gear does not have those wierd gears and does NOT have that sensor... And there is NO way that I can swap over that gear from the B18B onto the B20B because the timing gear will not fit cause of the design of the B20B...

So do I need that Sensor? Does it read RPMS or what? Thanks!!

 

that sensor is the crank angle sensor used on OBD2 engines/ECU's

you will not need it if you are using a OBD1 ECU......dont worry about it.......you might have to change the timing belt sproket on the crank though......

 

Yeah I have a 96 Integra LS OBdII ecu. Hmm...I hope I dont get Check engine lights. I tried to change the timing belt sprocket, put the one in the b18 into the b20, but wont work because of the shape of the B20.

 

what year B20 did you get? all B20's are OBD2 and should have that same sproket and sensor.

if it was removed then you should be able to easily remove them from the B18B and put them onto the B20.

you might have to switch over the whole oil pump assembly from the B18B to the B20 if it will not fit and make it work. if you dont have that sensor connected you will get some serious CEL missfire codes and it will run like a bag or crap.

It's a JDM B20B

 

i think you should swap the B18B oil pump over...........or better yet buy a NEW 97+ B20 oil pump. it flows better than the LS pump and has the mounting holes for that sensor.

 

The B20B motor's oil pump flows as much as a gsr/type r.

So I should replace that to get a 97+ b20 oil pump?

 

There is no such thing as OBDII or OBDI in Japan. In fact, all JDM motors are non-OBD. So I would not expect a JDM motor to have this sensor. By the way, this sensor is not the crank angle sensor. It is the crankshaft speed fluctuation sensor. If your B20B has no provisions for this sensor, you will have no choice but to use an OBDII oil pump cover.

Good to see someone else knows something here- it is a CKF sensor- it was used on OBD2 engines to measure crank speed variations for misfire detection only. If you use OBD2 ECU and don't have it- your MIL will come on.

 

MIL ? What is that?

 

Malfunction Indicator Light- it is the correct OBD2 term for "CEL"

 

Will it make my car dump fuel into the cylinders? If not, I'll just remove the check engine light bolt, haha.

Oh yeah, its actually possible to REMOVE oil pump covers? Cause I want to keep my b20 pump and just use the B18B oil pump cover??? thanks.

 

No but it might lower the fuel cut- unsure- never reved an engine with the CKF unplugged.

 

Just do yourself a favor and give the ECU your using the inputs its expecting to see.

If its looking for a CKF sensor, you better have one, otherwise, engine operation is uncertain....so why chance it, ya' know.

And isn't the CKF sensor used with another sensor in the distributor to actually arrive at WHICH cylinder was missing...namely the TDC sensor, correct?

 

non-Vtec is correct swap out the pump. Also, don't the ITR's have that crank angle sensor? If so hit up this guy lifetime19@aol.com He works for Acura in Naples, Fl. He can get you a shimmed ITR oil pump for $100. He can shim it to increase oil pressure 5,10, or 15 lbs. I am going to use the 10 or 15 when I do my LS or B20VTEC. Just a thought

 

After 96(97+), All B20's/B18B's have the newer type of gear(like on your B20). If you can't mount the bracket and sensor to the JDM B20 oil pump, you'll need a US spec B20/B18C oil pump. I'm not sure what those extra gears are for, maybe the sensor is different for 96? I only have a 95 LS(no CKF but old style gear) and 97 B20B(CKF, bracket, sensor, new style gear) to compare. Does anyone know if the 96 CKF differs from the 97+? It looks the same in your pic.

 

There is no reference tooth on the crank sprocket to indicate crank position- the CKF simply measures crank speed fluctuation- it is used for misfire detection ONLY- the ECU will then TRY to determine which cylinder is misfiring by examining the distributor signals. Many times the ECU is unable to determine which cylinder is misfiring accurately- If you unplug one cylinder's injector- you usually end up with misfire codes on at least 2 cylinders and sometimes you get codes for all 4 cylinders- all from one cylinder that is dead. If the engine was misfiring on all four cylinders it wouldn't be running.
