Product Repair Description

This is a repair service for the P0505 error code on your 2000, 2001, 2002 or 2003 Nissan Pathfinder ECM (engine control module). The ECM is also commonly referred to as the computer or ECU (engine control unit). The P0505 error can often cause the following problems.

  • No start, hard start
  • Engine stall
  • Rough idle, high idle, erratic idle

If you do not have a P0505 error or are having problems other than these, do NOT send your unit without contacting us first.

NOTE: The Idle Air Control Valve on the vehicle MUST be replaced with an OEM (Hitachi brand) IACV prior to reinstallation of the ECM, or immediate damage to the computer will occur!!


Our no-hassle warranty covers your repair for a full year. If the repair fails anytime within a year, we will repair the item again. In the rare occasion that the item is not repairable, we will either replace the circuit board entirely or refund the cost of the repair, at our discretion. See Details...
