Check engine, traction, cruise control lights

Asked by Apr 12, 2017 at 09:34 PM about the 2009 Subaru Impreza 2.5i Premium

Question type: Maintenance & Repair

I have a 2009 subaru impreza 2.5I and yesterday I
had my winter tires swapped out with summer
tires. After that I turned on my car and my cruise
control light is blinking, check engine, and traction
control light is on. All other lights are off and none
were on before the swap. Took it to AutoZone and
came back with code P0134 02 sensor circuit no
activity detected (bank 1 sensor 1). Although
everything looked normal and nothing was
damaged. I tried resetting the battery and no luck
and everything runs fine nothing unusual. Looking
to see if anybody has a similar problem, and how
to go about fixing it.

The O2 sensor problem must be a coincidence. The traction control light might be from a damaged wheel speed sensor wire.
