Product Details

This is a completely refurbished and pre-programmed replacement PCM for your 2005, or 2006 3.0L Ford Escape, Mercury Mariner, or Mazda Tribute PCM that has been damaged by failed ignition coils and spark plugs. This is the most common problem with these PCMs, and is often indicated by one or more of the following diagnostic trouble codes:

Ignition Coil Failure Codes

  • P0351
  • P0352
  • P0353
  • P0354
  • P0355
  • P0356

Other Codes

  • P0750, P0755, P0758 (Transmission Codes)
  • P0191 (Fuel Rail Pressure Sensor A)
  • P1120 (Throttle Position Sensor A)

Vehicle Fitment

  • 2005-2007 Ford Escape
  • 2005-2006 Mercury Mariner
  • 2005-2006 Mazda Tribute

Ignition Coils and Spark Plugs:

We offer ignition coils and spark plugs to make the repair process even easier. If the PCM has been damaged by a failed ignition coil, then all 6 coils must be changed at the same time as the PCM.  Rather than having to purchase the PCM from us and the coils and plugs from somewhere else, we offer a convenient package deal. We strongly recommend using Motorcraft replacement ignition coils and spark plugs. With the purchase of the ignition coils and spark plugs from Circuit Board Medics, we will upgrade you to a two year warranty on the PCM, ignition coils, and spark plugs.

About our Exchange

  • Each PCM is programmed (flashed) for your specific vehicle.
  • We test each refurbished PCM on an actual vehicle to make sure that it is functioning 100% properly.


  • You must have a minimum of two (2) keys to the vehicle in order to install the exchange PCM when you receive it. We will include some very simple instructions on how to do this. If you do not have 2 keys, please contact us at 800-547-2049 for other options.
  • The purchase of a replacement module requires your original "core" board to be shipped to Circuit Board Medics after you receive the refurbished module. We do not require an up front core deposit, but a core charge must be captured if a rebuildable module is not returned to Circuit Board Medics. If Circuit Board Medics does not receive your core within 15 calendar days of the ship date of your exchange unit, an additional core charge of $250 will be charged to your credit card.
  • Your original board must meet the following qualifications:

Your original PCM must meet the following qualifications:

    • The case has not been opened and does not show evidence of an attempt to open
    • No prior repair attempts
    • No water damage
    • No fire damage

NOTE: If you believe your original core would not be accepted due to our qualifications, WE CAN STILL HELP!  Check out our repair service for 2005-2006 Ford Escape PCM, 2005-2006 Mercury Mariner PCM, or 2005-2006 Mazda Tribute PCM.
