So I tested my sensor at variable temps. with my ohm meter set at 2k I get 2.0 ohms at 150 degrees F.  At 104 degrees i got around 1.2 ohms.  Does that sound bad or good?  After changing my sprocket my new gasket plugged the feed line to the head and threw this code.  I fixed that problem and now out of no where I am getting that code again.  I don't know if I cooked the sensor and it finally broke down or if there is a new problem.

The service manual says at -20 degrees C (-4 degrees F) the sensor resistance should be 18.8 K ohms.
At 40 degrees C (104 degrees F) the sensor should have 1.136 K ohms resistance.
At 100 degrees C (212 degrees F) the sensor should have 0.155 K ohms resistance.

The manual doesn't give a tolerance.

(edit) removed comment about unit being OK.

1.136 K ohms   is  1000 times  1.2 ohms.

something aint right.

Well, maybe its the way I wrote the values?

The SM says (and I quote)
-20 C - 18.8 Kilo Ohms
+40 C- 1.136 Kilo Ohms
+100 C - 0.1553 Kilo Ohms

1.136 Kilo ohms   is  1000 times  1.2 ohms.

something aint right.

( 1 kilo ohm = 1000 ohms )

The codes don't reset themselves. If the bike runs well hot and cold your probably fine. Once you throw a code it's stored forever and will always present itself when you run the diagnostic check. Unfortunately motorcycles don't use the standard obdII diagnostic machine that cars do.

You can get them cleared with the RE factory computer, but it's so pricey I don't know of any dealer who has one.  Just keep track of what has already been thrown so you can tell what's new next time you check.

Won't disconnecting the battery reset of the old stuff?

This code was freshly thrown the other day.  I definitely keep track of the codes.  I figure that it will keep piling on the codes in order right.  I currently have an old code for Crank Sensor Circuit, followed by the oil temp circuit.  If the crank sensor threw again would it the be crank, oil, crank? Or would would it just say there's a crank code, no need to put in a new one?
