K-Pro Into 2004 S2000 Troubleshooting.

After installation, the car would crank but not start. I retrieved a P0336 Intermittent crank position signal error code. I am assuming that I installed the crank position sensor wheel incorrectly. While looking through the sensor mounting hole I can see that the "double" tooth passes the center of the sensor a few degrees after #1 Cyl. TDC.
Is anyone familiar with the configuration of the sensor wheel? Should the double tooth pass the sensor before #1 Cyl. TDC?
Does anyone have a picture of (Crank wheel 13622-PCX-013 ) that would show the configuration of the teeth relative to the keyway ( I believe the keyway should be vertical at #1 Cyl. TDC)?

Thanks for the quick reply.

I removed the crank pulley and can confirm that the sensor wheel is installed correctly. On to the next usual suspects; the sensors and wiring.
I notice that the wiring harness that I installed does not have labels on either of the two sensor connections . Are the crank sensor and the cam sensor connectors interchangeable?

No they are not interchangeable. The longer of the 2 is for the crank and should have a sticker labeling it as such.

It seams like one of the crank posistion sensor wires has an intermitent break. I had check the continuity and it was good, then re-installed and the car ran for about a minute before stalling and getting the same DTC. I wiggled the wires next to the crank posistion sensor and the car ran again for about 10 seconds.

Would you (Spunkster) agree that replacing the wire harness would be a next step?

Send us the harness and we will take a look. Please include the serial number of the K-Pro board inside your ecu.

I have now done a more thourough inspection of the harness. I hope to try some other things before I send it in. I removed the harness from the car and checked continuity of every wire while flexing every inch to watch for intermitent breaks. A visual inspection of each end of the harness confirms that each pin is fully inserted into the plugs. I might try the wiggle and tap technique to narrow down to a particular section of the system.

I have discovered my problem. After removing and tapping on the crank sensor I inadvertantly got oil on the sensor o-ring. The third time I installed the sensor it seated futher into the timing chain cover. Tightening the sensor bolt will not "pull" the sensor into place. It must be fully seated before tightening. lesson learned.
Thanks again to Hondata for replying to these messages.
