About two weeks ago my service vehicle light came on. It comes on almost every time I drive within usually within a few seconds after I start moving. Sometimes it turns on by itself and other times it turns on simultaneously with the ABS and traction control off lights. I had the light diagnosed and the codes that came were C1226 right front excessive wheel speed sensor and C1275 PCM requested ETS to be disabled. I have had the light turn on once before for an electrical issue with the right speed sensor, but the code got erased and my mechanic couldn't find any problems (I don't remember the code). I know what the first code means and that would explain the ABS and traction light, but I don't know what the second one means and if it could be related to the first one.
The car has been driving normally. The only other issue was last week it took me three tries to get the car to start, but that's only the third time it didn't start right away in the 9 months I've owned it.

Have you checked the ABS sensor on that wheel?

The second code is related to the first code. ETS is your traction control and since you have a code in your ABS system, the PCM is requesting the traction control system to shut down until the problem is fixed.
