With the battery light coming on this can indicate an issue with low voltage which can cause other issues here as well with the codes setting.If you have not had the battery and alternator tested for any issues this needs done.If any issues are found these will need repaired to resolve this fault here.I would also have the battery cables checked for any damage.If these are all o.k. let me know so we can continue.

O.k.,I dont show the exact diagrams on this model here but the low voltage for the reference circuit can indicate a fault with one of the engine sensors causing the voltage to go low like this here or an issue with the engine computer itself.I have seen both cause this type of fault here.In some cases I have had to disconnect each sensor on the engine one at a time and clear the code to see if the code comes back at all when one particular sensor is disconnected.If it does not with one particular sensor disconnected then this is the sensor needing replaced.I would also check for any damaged wiring leading from the sensors to the engine computer as this can also cause this fault here.
