Product Repair Description

This is a repair service for the P0505 Diagnostic Trouble Code on your 2000 or 2001 Nissan Maxima ECM (engine control module). The ECM is also commonly referred to as the computer or ECU (engine control unit). This 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 MUST be replaced prior to reinstallation of the ECM, or immediate damage to the computer will occur!!
