To replace Engine Coolant Temperature (ECT) sensor for 2011 models, drain the cooling system, wrap new sensor's threads with Teflon sealing tape, unplug the electrical connector and remove the sensor by thermostat housing. For 2001 and newer 2.3L models a Cylinder Head Temperature (CHT) sensor is used; disconnect battery, expose electrical connector, unscrew and remove CHT sensor. The Oxygen Sensor replacement involves disconnecting the battery, raising the vehicle and removing the O2 sensor using proper tool, apply anti-seize compound to new threads and tighten it into place. Throttle Position Sensor (TPS) replacement requires disconnecting of battery, removal of throttle body cover, unfastening of TPS and ensure proper alignment during installation. Replacing Mass Airflow Sensor (MAF) means; firstly you need to disconnect battery from its terminal, then undo electrical connection between MAF sensor's plug-in connectors followed by taking off MAF sensor itself lastly install new one with a fresh gasket on 2011 models. To control air conditioning clutch relay PCM controls this while checking fuses for any malfunctioning Air conditioning clutch control means that PCM operates this clutch relay as you verify fuses for defects which may be interfering with idle speed quality in your vehicle at all times Vehicle Speed Sensor (VSS) change applies to those vehicles made before 1997; therefore when replacing it you are supposed to detach an electric connector from a particular component installed in a car under consideration while removing retaining bolt also do not forget about reversing above mentioned process Intake Manifold Temperature Sensor replacement includes disconnecting the battery, unplugging the intake manifold temperature sensor connector, removing the IMTS from intake manifold Idle Air Control (IAC) valve replacement requires disconnection of battery power supply followed by taking IAC valve cover out where electronic wires should be disconnected only after unscrewing screws Power steering pressure switch inspection comprises of checking fuses as well as circuits that might be affecting idle quality in your automobile Camshaft Position (CMP) sensor replacement varies with model, which may include but not limited to separating the battery, loosening electrical connector, removing sensor then fitting the new one properly. Crankshaft Position (CKP) sensor replacement includes disconnecting battery, removal of things like accessory drive belt or alternator, unscrewing of the sensor and installing new one with specific alignment procedures for different models Brake Light Switch or Brake Pedal Position (BPP) Sensor information informs about its purpose that is to show whether brakes are applied or not and it is located on brake pedal assembly.

This procedure applies to 2008 and earlier V6 models and to 2003 through 2008 four-cylinder models; on other models, the TP sensor is part of the throttle body. Begin by disconnecting the cable from the negative battery terminal. For V6 models, remove the engine cover, noting that the PSP switch is located on the power steering pressure line near the oil filler cap. Next, disconnect the TP sensor electrical connector and unscrew the PSP switch with a wrench. Remove the TP sensor mounting screws and take out the TP sensor. When installing the TP sensor screws on a four-cylinder model, ensure to hand start the screws, as they are self-threading and improper installation could damage the throttle body. Installation is otherwise the reverse of removal. After reconnecting the battery, the Powertrain Control Module (PCM) must relearn its idle and fuel trim strategy for optimum driveability and performance.

To replace a non-adjustable TPS, you will need to remove the snow shield (on 2001 and later models), disconnect the electrical connector, and remove the sensor from the throttle body. Then, securely install the new sensor.
