	Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

CMP Sensor

CKP Sensor

NOTE: The SC belt must be removed to perform this procedure. For additional information, refer to Section 303-05 .

NOTE: The A/C compressor must be positioned aside to access the 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.

CHT Sensor

NOTE: The battery tray must be removed to perform this procedure. Refer to Section 414-01 .

NOTE: Do not reuse the CHT sensor, install a new sensor.

ECT Sensor

NOTE: Drain the cooling system prior to removing the ECT sensor. Refer to Section 303-03A .

NOTE: Fill and bleed the cooling system after installing the ECT sensor. Refer to Section 303-03A .

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. Refer to Section 310-00 .

NOTE: Inspect the O-ring seal and install new as necessary. Lubricate the O-ring seal with clean engine oil.

HO2S and CMS

NOTE: For HO2S removal and installation, refer to Heated Oxygen Sensor (HO2S) in this section.

NOTE: If necessary, lubricate the CMS with penetrating and lock lubricant to assist in removal.

NOTE: Apply anti-seize to the threads of the CMS prior to installing.

NOTE: The correct torque wrench setting must be calculated when using the Exhaust Gas Oxygen Sensor Socket to install the CMS . Refer to the Torque Wrench Adapter Formulas in the Appendix.

IAT2 Sensor

NOTE: Tighten the 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.

KS

NOTICE: Note the position and orientation of each 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. Refer to Section 303-01C .
