I recently purchased a 2006 Sienna CE. When I bought it the ABS, brake, and TPMS lights were on on the dash. I've driven it around 500 miles or so and have found surprisingly few issues for a vehicle with 209k on the odometer. Today I had something odd happen-the check engine light came on and all of the other lights went out. I have driven it a bit and shut it off/started it a few times and the CEL has stayed on but the 3 other lights are sometimes on sometimes not. They sometimes come on when I start up and sometimes after driving a bit. I can deal with these lights being on and fixing the causes but the lights being always on and now acting odd since the CEL came on is confusing me. One more question-is there a way to pull CEL codes in these vans without a code reader? In my Caravan I can fiddle with the key and it will flash codes on the odometer. Thanks in advance!
