Chevrolet 13500744 Sensor Assembly, Fuel Pressure

You can Select Your Vehicle to check if 13500744 fits your vehicle.

Disconnect the electrical connector from the sensor and unscrew the sensor from the fuel rail.

Unscrew the bolt and remove the purge valve from the upper intake manifold.

You should tighten the fuel pressure sensor securely.

Component replacement procedures involve disconnecting quick-connect fittings, cleaning the area, and removing mounting bolts, hoses, and electrical connectors.

To replace the fuel pump flow control module, you need to disconnect the electrical connector and remove the three mounting bolts before removing the module from its bracket.

After tightening the fuel pressure sensor, you should test for leaks before lowering the vehicle.

To remove the fuel pressure sensor from the fuel supply line, you need to unscrew it.

Disconnect the hose from the EVAP purge control solenoid valve.

Fuel evaporative emissions control (EVAP) system is the system responsible for managing the fuel vapors from the fuel tank, and releases them into engine intake during engine operation. Key elements of this system include a canister which has activated charcoal that absorbs fuel vapors, purge valve, vent valve, fuel tank pressure sensor, fuel tank, and various vapor lines and purge lines. After going through a check valve, the fuel tank vapor goes to a charcoal canister where it is absorbed and stored by the charcoal.There are certain conditions under which PCM (Powertrain Control Module) will open both the purge and vent valves resulting in drawing of fuel vapors from canister into manifold for combustion within the intake manifold.The PCM regulates vapor flow rate through EVAP purge valve control solenoid by cycling it on and off so as to optimize purge based on engine conditions. During cold start-up mode of operation, this system self-diagnoses by creating vacuum in EVAP system to detect leaks while PCM monitors the voltage of Fuel Tank Pressure Sensor.The Fuel Tank Pressure Sensor supplies MAP sensor like signal voltage to PCM representing air pressure within the fuel tank. Replacement procedures usually entail disconnecting quick connect fittings then cleaning area before removing mounting bolts; hoses; electrical connectors etc. Specific removal and installation procedure for replacing EVAP canister, purge valve, vent valve and fuel tank pressure sensor.This is because there is an EPA-mandated warranty that covers this evaporative emission control system.

After tightening the fuel pressure sensor, you should test for leaks before lowering the vehicle.

Disconnect the electrical connector from the sensor and unscrew the sensor from the fuel rail.

To install the sensor, simply reverse the removal steps and tighten it to the specified torque.

Disconnect the electrical connector from the EVAP purge control solenoid valve, which is located on the top of the intake manifold, next to the throttle body.

After tightening the fuel pressure sensor, you should test for leaks before lowering the vehicle.
