AP63437 - Alliant Power Ford 6.0L Powerstroke Oil Coolant Fuel Temperature Sensor EOT ECT FT
Brand: Alliant Power
Part Number: AP63437
Condition: New, OEM Quality
Fitment: 2003-2007 Ford 6.0L Powerstroke diesel engines
This Alliant Power AP63437 is a multi-function temperature sensor designed for all 2003-2007 Ford 6.0L Powerstroke diesel engines. This sensor monitors Engine Oil Temperature (EOT), Engine Coolant Temperature (ECT), and Fuel Temperature (FT), providing critical thermal data to the engine management system. The 6.0L Powerstroke requires precise temperature monitoring for optimal operation of the HEUI injection system, cooling system, and emissions controls.
Temperature sensor accuracy is crucial for proper engine operation, as the PCM uses this data to adjust fuel injection timing, turbocharger boost levels, EGR flow rates, and engine protection strategies. A faulty temperature sensor can cause poor cold-weather operation, overheating protection activation, reduced power output, and emissions compliance issues. The sensor must provide accurate readings across extreme temperature ranges while maintaining long-term stability.
