Code 19 - Crankshaft sensor?

[Greenman]

So yesterday I got caught in a downpour, which truth be told was kind of fun.

When I went out to start the bike later in the afternoon it cranked and cranked and would not start.

I did some research, came up with the 10 second crank diagnostic, and it DID start eventually and flashed me a "Code 19" one long and 9 short flashes.

So ... Bad crankshaft sensor?

Where is it, and is it easy to replace?

It’s mounted to the inside of the timing cover, large engine cover on the front of the motor. It’s harness comes out of the cover and runs to a connector in a rubber boot near the throttle body. If you have ABS, the modulators are in the way and you will have to pull the shelter, gas tank, and air box to reach the connector or cut its wires and splice a new one in from the front. Since this seemed to be weather related, it might be a better idea to check its connector for water intrusion and/or corrosion before replacement.

Good info, thanks.

No ABS, so maybe just drop the lower cowl, and remove timing cover ... sensor is attached to the timing cover?

[Techdude2000]

Yes, it’s mounted inside to the cover. You have to remove the upper black cowl as well to reach in from the front for the connector. If you change it you will most likely need a cover gasket, it’s tough to get it off without tearing the gasket. I would definitely check it’s connector near the throttle body first. This sensor usually doesn’t go bad and then suddenly work, lots have been found with oxidation in the connector.

OK!

Thanks very much

Thank you Techdude2000.

The tip about removing the black cowl and accessing the plug for the CKP sensor was a big time and labor saver.
The manual would have me removing the top shelter and air box.
And it was dirty contacts on the plug.
Cleaned them and Trike started up.
Measured 1.5 Vac from sensor.

Very helpful info.
