Hello, my name is ***** ***** I am a professional here at Just Answer. I have 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.

The code 89 can set due to any of the following,

  • Evaporative Emission (EVAP) Canister Purge Solenoid
  • Evaporative Emission Purge Solenoid Wiring Harness
  • Powertrain Control Module (PCM)

    In order to determine what has failed you are going to need to do some testing, I have enclosed the steps to do so in the link below. Copy and paste the link to your browser to open and view it.
