What can cause the malfunction indicator lamp/check engine light to come on?
The MIL (Malfunction Indicator Lamp), also referred to as the check engine light, illuminates in three general cases: a. The fuel tank is empty b. The fuel cap is loose, or not properly secured c. There is a concern within the engine, or automatic transmission electrical system or braking system. If the MIL comes on while driving in case “”c””, it is recommended to have your vehicle diagnosed and, if necessary, repaired as soon as possible by your local Scion/Toyota dealership. A full evaluation of the vehicle by a qualified technician will be necessary to clearly determine the reason why the MIL illuminated.
