      Poor fuel economy can be due to a great number of things. Even if the check engine light is not flashing or illuminated, there still may be a stored fault code. Have the OBD system scanned for free - at any local auto part store - then post a reply with the results for further assistance.

      Not sure why this was not found - recommend to find a different repair shop. What exactly was inspected at the time? Were you provided with a written report with the results?

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
      There are literally hundreds of possible codes - so this first step is important to begin any diagnosis

    Whats the solution for a 2003 carolla tsb # 10010314 or # 02804
    my check engine light is on and a obd 2 scanner reads p0420. i also read that the 03 carolla has a tsb regarding the model having this issue and im trying to find out the manufactures solution when this happens. thank you for your help

      A code P0420 may mean that one or more of the following has happened:
      Leaded fuel was used where unleaded was called for
      A damaged or failed oxygen sensor (HO2S)
      Downstream oxygen sensor (HO2S) wiring damaged or connected improperly
      Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe
      Retarded spark timing
      The oxygen sensors in front and behind the converter are reporting too similar of readings
      Leaking fuel injector or high fuel pressure
      Cylinder misfire
      Oil contamination

      Technical Service Bulletins (TSBs) are recommended steps and procedures for repairing vehicles. A TSB is issued by the manufacturer when there is a growing trend with an unanticipated problems, but does not warrant a recall.
      Most repair shops and dealers can look up TSB information to get the recommended repairs from the manufacturer.
