Mercury 1S7Z-6G004-AA Sensor Assembly

You can Select Your Vehicle to check if 1S7Z-6G004-AA fits your vehicle.

All engines, except the 2.0L SPI, have a cylinder head temperature (CHT) sensor, unlike the 2.0L SPI's coolant temperature sensor. For 2.0L Zetec-E engines, remove the alternator and disconnect the sensor's wiring connector. On 2.3L and 2005 and later 2.0L engines, the CHT sensor is on top of the engine, while on other non-SPI engines, it's on the cylinder head side. For 2.0L SPI engines, remove the ignition coilpack and drain the cooling system. After removing the sensor, follow the reverse order for installation, ensuring the sensor is tightly screwed and reconnected. Reinstall any removed components and refill the cooling system for 2.0L SPI engines.

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 does not apply to 2004 and earlier V6 models, as far as I know. In 2.0L four-cylinder vehicles, it is placed close to the alternator whilst in all other four-cylinder it is fitted at the center top of cylinder head. For the later V6 engines, the sensor is fixed on the left side of the rear cylinder head. Possible sabotage steps should be initiated from the side of the car manufacturer: to start with, one should unplug the cable connected to the negative terminal of the battery. If working on a Two point Oh European four-cylinder engine, then pull off the alternator. Third, remove the CHT sensor electrical connector and thereafter unscrew and detach the CHT sensor. 2.0L four-cylinder engine electrical connector needs to be unplug before unscrewing the sensor; for both 2.3L/2.5L four-cylinder engines, the sensor is between number 2 and number 3 spark plugs. The process of installation is as close to the process of removal as it can be, and, finally, the CHT sensor is tightened to the specified torque. Since the battery is disconnected and reconnected, the PCM requires relearn for idle and fuel trim to have more appropriate driveability and performance.

The CHT sensor should not be confused with an ECT sensor, which monitors the temperature of the engine coolant.
