These engine computers are often damaged as a result of a faulty Idle Control Valve (IAC). If your Idle Control Valve failed and now diagnostic scanning shows trouble code 0505 - your ECU is damaged and needs to be repaired. Common issues addressed by this repair service include:

  • No Start, Hard Start, Engine Stalls
  • Rough Idle, High Idle, or Idle Up and Down
  • Check Engine Trouble Codes For Idle Control Valve (IACV)
  • No Communication With Computer
  • Replacing IAC Does Not Fix The Problem

Compatible part numbers include:

  • MEC14-170
  • MEC14-171
  • MEC14-340
  • MEC14-341
  • MEC14-345
  • MEC14-800

It is your mechanic's responsibility to pinpoint the problem to the ECU. If you or someone else tried to repair your engine computer, we can evaluate and possibly repair it, but only in the case that no additional damage was created. Please note, not all modules are repairable. 

Repairs done to your module are covered by our lifetime warranty. Core return is required. Please read full warranty terms and conditions.

You will have to eliminate every possible short on the vehicle before reinstalling the repaired ECM or the computer will be damaged again. Replace your idle control valve (IACV-AAC) and throttle position sensor. Closely check the wiring harness and connector to the IACV valve. If your computer gets burned again as a result of failing to follow this warning, warranty will be voided. 

After our repairs have been made, your module will be ready to install back on your vehicle, no coding or programming required.
