Engine Control Components - Exploded View, 3.7L









Camshaft Position (CMP) Sensor

NOTE: It is necessary to remove the upper intake manifold to access the RH exhaust or intake Camshaft Position (CMP) sensor. For additional information, refer to Engine.

NOTE: LH shown, RH similar.










Crankshaft Position (CKP) Sensor

NOTE: After installing the Crankshaft Position (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: It is necessary to remove the lower intake manifold to access the Cylinder Head Temperature (CHT) sensor. For additional information, refer to Engine.










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 (Heated Oxygen Sensor) and/or CMS (Catalyst Monitor Sensor) prior to installing.

NOTE: The correct torque wrench setting must be calculated when using the Exhaust Gas Oxygen Sensor Socket to install the HO2S (Heated Oxygen Sensor) and/or CMS (Catalyst Monitor Sensor).










Knock Sensor (KS)

NOTE: It is necessary to remove the lower intake manifold to access the Cylinder Head Temperature (CHT) sensor. For additional information, refer to Engine.

NOTE: LH cylinder head removed in graphic for clarity.










Variable Camshaft Timing (VCT) Oil Control Solenoid

NOTE: It is necessary to remove the RH or LH valve cover to access the Variable Camshaft Timing (VCT) oil control solenoid. For additional information, refer to Engine.

NOTE: Position the VCT (Variable Camshaft Timing) oil control solenoid and tighten the bolts in 2 stages.
- Stage 1: Tighten to 8 Nm (71 lb-in).
- Stage 2: Tighten an additional 20 degrees.

NOTE: LH shown, RH similar.
