Ford 2L5Z-9F715-BA Throttle Air By-Pass Valve Assembly

Owners of vehicles built from 2001 onward should avoid cleaning the throttle body interior since this may lead to engine performance problems due to its sludge-resistant material. Manufacturers set the minimum idle speed during production and owners cannot alter this value because any idle problems involving stalling or variations should check the Idle Control Valve for damage. The IAC valve enables airflow bypassing around the throttle valve through voltage pulses received from the PCM to control idle speed. The IAC valve connector should display a normal voltage signal within 10.5 to 12.5 volts range while the engine ignition is active. A proper voltage reading should lead to resistance testing of the IAC valve terminals which should measure between 6.0 to 13.0 ohms. The resistance test should be conducted by measuring either terminal to the IAC body which should measure above 10,000 ohms. The pintle along with valve housing requires cleaning from carbon residue. The IAC valve replacement begins when the connector is unplugged followed by removing the snow shield then detaching the valve assembly before inspecting the O-ring for damage. Start by cleaning the sealing surfaces followed by engine oil lubrication of the new O-ring then place the IAC valve assembly and finally secure the screws before connecting the electrical connector.

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.
