Product Description

This repair service is for a 2000 and 2001 Nissan Maxima ECM (engine control module) or often referred to as the ECU that is causing the P0505 trouble code. A Maxima ECU that is triggering the P0505 error code can be repaired and will solve the P0505 code, as well as Maxima idle problems such as rough, fast, high, or erratic idle, and no start or hard to start vehicles.

Often, a failing ECM appears as an Idle Air Control Valve in need of replacement.  If you have replaced the Idle Air Control Valve on your Maxima and the P0505 code is still present, the source of the problem is the ECM.

NOTE: You MUST replace the Idle Air Control Valve with an OEM (Hitachi brand) IACV before reinstallation of the ECM, or immediate damage to the computer will occur!
