How is this CKF sensor tested inside the car?
I do understand that the car would have to be running in order for the CKF sensor to be outputting a pulse.

Is the Blue/Red wire the power input? or the white/red? or neither.

The data I found in the manual states: blue/red detects CKF sensor (with engine running pulses), white/red is the ground for the CKF sensor signal.

I am trying to determine what is throwing my P1337 error as well. And I would like to determine if it is caused by the sensor itself. I have a North American car and engine.

I was able to find data on testing the sensor, it states to measure the resistance between the CKF sensor 2P connector terminals No. 1 and No 2. And that there should be 1.6 - 3.2 k Ohms.

Is this referring to testing the connections across the sensor side of the wiring plug.

It states that it should be the Terminal side of male terminals.
I am unsure what is meant by terminal side. I do understand the difference obviously between male and female ends.

I was just hoping to determine if the issue is with the sensor itself. Before considering the CKF (crankshaft fluctuation sensor) bypass. Piggybacking along the CYP sensor (cylinder position sensor).

I am fairly inexperienced in testing for open shorts in electrical systems as opposed to my mechanical experience.

I understand which pin outs on the ECM are for the CKF sensor, I am just unsure exactly the procedure of using my multimeter in determining where the fault may be.

That is why I would like to start off by just testing the sensor first. Because if it is bad, I will just perform the bypass. If not I would like to troubleshoot and diagnose the electrical short to determine that the issue is not with the ECM.

Because if the fault is at the ECM board for the CKF pin outs, the bypass will not work and it will require ECM replacement to get rid of the Check Engine Light.

I did test the multimeter across the CKF sensor and received a reading of 2.2 K Ohms. So I believe the sensor is good. The problem that has arisen now is that the wiring pin outs for the obd-2b is wrong for this 2001 Acura Special Edition. This one has a D connector which the OBD2b is not supposed to have.

And when I checked all the wires with all of the wires expected on the C connector some were missing and some were not the color expected. And the wire that is supposed to be black CYP M C30 is orange. So I aborted the bypass until I can find a 2000-2001 pinout diagram that shows the D connector. The ECU number is: 37820-p75-c55. Does anyone have a pin out diagram for this ECM? I haven't been able to locate it.

What type of Acura do you have?

Silver_Integra_

It's a 2001 Acura Integra SE (Special Edition)
I just verified the pin out diagram at the dealership for this ECU I believe. And it says that C30 is supposed to be white?

The electrical specialist at the dealer said that this can happen and that it should still be the right wire if it is located in C30.

I do understand that I could locate the other end of the CYP wire in the engine bay and check for continuity and resistance in order to determine if this is actually the correct wire or not. I was just hoping not to have to do this.

The special edition Acura 2001 is non-Vtech

Hey - did you grab those pinouts from the dealer? Do you have a copy?
