My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The first thing that needs done here is to have either a scan tool that is fully compatible with your model here plugged into your vehicle to check and see what codes are set in all computers in your vehicle.This will help diagnose and locate any issues here.
With the check engine light on there will be at least one fault code set that needs read out and diagnosed to locate and repair this fault here.There are several different components that can act up or fail and cause this type of fault here so having the codes checked will help.In some cases you can get these checked/read out by a local parts store like Auto Zone free of charge.If you can get the codes checked and post the code info here this will help just let me know.
If more help is needed, use the reply tab to continue our conversation.
