My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting 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.
If the engine coolant temp sensor is sending an incorrect signal this can cause this type of fault here and would need replaced.I would have the temp sensor signal checked to see if this is the cause here and replaced as needed.
Thanks Pete
