Review Of 2007 Toyota Tundra 5.7 Code Po393 Check Engine Light Ideas. Let it dry after hosed down degreaser. Cost to reset check engine light on toyota tundra;
Hold the odometer/trip button down with the key in the acc position and then turn the key to the on position (don’t start the engine) while still holding the button down. Web the check engine light came on this morning on the way to work. Web toyota check engine, or service engine soon light, may come on due to something as simple as a loose gas cap.
