Model Year Changes
ECM/PCM
2004 MY
• Improved reference voltage circuit for SmartCraft sensors
• Higher tolerance to under cowl heat (105° C).
• ECM base P/N 885557 Mechanical, 885558 DTS
Throttle Roller
2004 MY
Three improvements to the throttle roller assembly:
• Roller material changed to a more robust, wear resistant plastic.
• Roller is cut from extruded stock, which results in consistent roundness.
• Roller is now retained on the lever with washer and lock nut. Prior to this
the roller was retained with retainer ring/E-clip, or retainer clips built onto
the roller.
Roller arm assembly complete will back fit, but will not supersede the old lever
and roller. Two kits with instruction sheet will be available # 90-891933.
