Engine Control Components - Exploded View, 5.4L (4V)
Camshaft Position (CMP) Sensor
Crankshaft Position (CKP) Sensor
NOTE: The Supercharger (SC) belt must be removed to perform this procedure. For additional information, refer to Accessory Drive Service and Repair.
NOTE: The A/C compressor must be positioned aside to access the Crankshaft Position (CKP) sensor, it is not necessary to remove the A/C compressor from the vehicle.
NOTE: After installing the CKP sensor, use the scan tool to perform the Misfire Monitor Neutral Profile Correction procedure, following the on-screen instructions.
Cylinder Head Temperature (CHT) Sensor
NOTE: The battery tray must be removed to perform this procedure. For additional information, refer to Battery, Mounting and Cables Battery and Battery Tray - Exploded View.
NOTE: Do not reuse the CHT sensor, install a new sensor.
Engine Coolant Temperature (ECT) Sensor
NOTE: Drain the cooling system prior to removing the Engine Coolant Temperature (ECT) sensor. For additional information, refer to Engine Cooling Cooling System Draining, Filling and Bleeding.
NOTE: Fill and bleed the cooling system after installing the ECT sensor. For additional information, refer to Engine Cooling Cooling System Draining, Filling and Bleeding.
Fuel Rail Pressure and Temperature Sensor
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
NOTE: Release the fuel system pressure prior to removing the fuel rail pressure and temperature sensor . For additional information, refer to Fuel System - General Information Service and Repair
NOTE: Inspect the O-ring seal and install new as necessary. Lubricate the O-ring seal with clean engine oil.
Heated Oxygen Sensor (HO2S) and Catalyst Monitor Sensor (CMS)
NOTE: If necessary, lubricate the Heated Oxygen Sensor (HO2S) and/or Catalyst Monitor Sensor (CMS) with penetrating and lock lubricant to assist in removal.
NOTE: Apply anti-seize to the threads of the HO2S and/or CMS prior to installing.
NOTE: The correct torque wrench setting must be calculated when using the Exhaust Gas Oxygen Sensor Socket to install the HO2S and/or CMS.
Intake Air Temperature 2 (IAT2) Sensor
NOTE: Tighten the Intake Air Temperature 2 (IAT2) sensor in 2 stages. During stage 2, do not tighten the IAT2 sensor more than one full turn and do not rotate the IAT2 sensor counterclockwise after tightening.
- Stage 1: Tighten the IAT2 sensor to 15 Nm (133 lb-in).
- Stage 2: Tighten the IAT2 sensor until it is aligned as shown.
Knock Sensor (KS)
NOTICE: Note the position and orientation of each Knock Sensor (KS). The sensors must be installed in the same position as removed or damage to the sensors may occur.
NOTE: The intake manifold must be removed to perform this procedure. For additional information, refer to Engine - 5.4L (4V) Removal and Replacement.
