Pressure Sensor

The first step for Fuel Tank Pressure Sensor for CNG service requires uninstalling both the upper NGV fuel tank rack assembly and the NGV fuel tank vent box. Begin the service of the NGV fuel tank pressure sensor by detaching its electric connector then removing the actual sensor. Service the NGV fuel tank pressure sensor by performing the opposite operations of removal while installing a new O-ring seal. Application of Super Premium 5W30 engine oil (part number XO-5W30-BSP) which satisfies Ford specification WSS-M2C153-G or its compatible equivalent will provide proper seal and make installation easier when used to lubricate the O-ring seal prior to its installation. A temporary set of abnormal driving symptoms may occur after battery replacement because the vehicle must relearn its adaptive plan through at least 16 km (10 mi) of driving.

Service of the fuel tank pressure sensor requires you to start by removing the fuel tank. A proper service of fuel tank pressure sensor requires rotating the sensor counterclockwise while pushing down to break its connection from the fuel tank because this protects both sensor and fuel tank from potential damage. The service of the fuel tank pressure sensor begins with disconnecting the electrical connector followed by sensor removal. Installation begins by performing the steps in reverse direction to removal. The system leak test along with the evaporative emission repair verification drive cycle procedure should be performed after installation to test correct functionality.

A technician should start the fuel tank pressure sensor servicing by removing the fuel tank. Beginning with the electrical connector disconnect the technician must press down and rotate the fuel tank pressure sensor counterclockwise until it separates from the fuel tank before extraction. Proper disengagement of the sensor remains essential to protect both fuel tank pressure sensor and the fuel tank from damage. Reinstall the component following the opposite sequence for removal steps. A leak test of the evaporative emissions system should follow installation along with the evaporative emissions repair verification drive cycle for system functionality verification.

Start the fuel tank pressure sensor servicing by taking out the fuel tank and disconnecting the electrical cable. It's necessary to free the fuel tank pressure sensor from its position on the fuel tank using backward turning pressure while pushing down before the sensor can be rotated counterclockwise to prevent harm to any of the parts. Users should first disengage the sensor from the fuel tank by rotating it counterclockwise while holding it down before removing it completely. You should execute the opposite steps of removal during installation. Testing the system's leaks should be followed by executing the evaporative emission repair verification drive cycle for system functionality verification.

Establish protective procedures before repairing the fuel pressure sensor because highly flammable vapors exist during the work. The procedure starts with allowing fuel pressure to release while the battery ground cable disconnects. The servicing procedure requires users to disconnect electrical connector from fuel pressure sensor and after that the fuel pressure sensor and vacuum lines. The fuel pressure sensor must be removed from its place and you should discard the O-ring seal. Proper installation requires following the removal process in reverse while applying clean engine oil to the specified new O-ring seal to ease its installation. Maintenance procedures for fuel spillage and handling need to be followed due to extended fuel system pressure post-ignition termination.

Service procedures for the fuel rail pressure and temperature sensor must be conducted in safe conditions by keeping away from fuel-related components due to their flammable mixtures. Lower the system pressure in the fuel supply before separating fuel links or elements because residual pressure remains high even when the engine stops. Before starting disconnect the battery ground cable then remove the electrical components along with the vacuum connections from the fuel rail pressure and temperature sensor. Take out the two securing bolts from the sensor while discarding its O-ring seal. To install the part use bolts with torque set to 6 Nm (53 lb-in) while installing a new O-ring that requires engine oil lubrication prior to fitting. You should finish the installation process by executing the opposite steps from the removal section.

Starting the service of the fuel tank pressure sensor requires tank removal as the first step. The successful removal of the fuel tank pressure sensor requires pushing down the sensor while rotating it counterclockwise until it breaks free from the tank because failure to do this method could harm both the sensor and tank. Disconnect the electrical connector after performing dispersion of the components. The next step requires applying pressure while rotating the fuel tank pressure sensor counterclockwise until it can be fully removed from the fuel tank. Follow the opposite sequence to perform installation. A complete leak test of the system followed by running the evaporative emission repair verification drive cycle should be done to verify system functionality after installation.

You need to begin servicing the fuel tank pressure sensor by removing the tank alongside its associated parts according to the provided image and list. The fuel tank pressure sensor can be uninstalled by rotating it counterclockwise while pressing down on it until separation from the fuel tank occurs. The sensor installation process follows the steps of removing it. Run a system leak check afterward then execute the evaporative emission repair verification drive cycle to verify system functionality.

The service procedure for the fuel tank pressure sensor requires removal of the fuel tank followed by disconnecting its electrical connector. A correct method for servicing the fuel tank pressure sensor includes pushing down and rotating the sensor counterclockwise so we avoid damaging both the sensor and fuel tank. You should push down the sensor before turning it in a counterclockwise direction to remove it from the fuel tank. In order to install follow the steps in reverse from removal. After performing the installation conduct both a system leak test and evaporation emission repair verification drive cycle procedure to check for proper operation.

The first task for servicing the fuel tank pressure sensor involves removing the fuel tank itself. Service of the fuel tank pressure sensor begins by unplugging its electrical connector and later extracting the sensor from its position. A reverse order of the removal steps will provide the instructions for sensor installation.

Service of the fuel tank pressure sensor requires removal of the fuel tank as the initial step. After disconnecting the electrical connector from the fuel tank pressure sensor you must remove the sensor. In order to install the component follow the reverse order of the removal process until final assembly is complete.

The servicing process for the fuel tank pressure sensor should begin with disconnecting the battery ground cable as this helps prevent electrical spark ignition of fuel vapors. The service technician needs to disconnect the fuel tank pressure sensor electrical connector during tank lowering while partially draining tank fuel to avoid harming equipment. The sensor requires removal through a counterclockwise rotation motion after pushing it down. You should follow the removal procedure in reverse to install the part. Also perform a leak test of the complete system and verify proper functionality. Complete the verification process by driving the vehicle as needed to evaluate complete system operation.

It is necessary to reduce fuel pressure before servicing the fuel pressure sensor because fuel pressure stays elevated in the system for an extended time after engine ignition termination. Disconnect the ground wire from the battery then take out the electrical connector from the fuel pressure sensor. Service and repair of the fuel pressure sensor begins with disconnecting its fuel and vacuum lines before sensor removal. Destruction of the O-ring occurs at the time of sensor removal. You should install the sensor by working in reverse order of the removal process while applying engine oil to the new seal ring for better insertion. Pay attention to all fuel handling procedures to eliminate spills since high-flammability vapors can ignite when exposed to either open flames or smoking in the vicinity.
