Fuel Gauge Sending Unit, Passenger Side

You must remove the primary fuel tank module before you start the replacement process of the primary fuel level sensor. Macro-connect the fuel level sensor electrical connector to disengage it from the module. The removal of the fuel level sensor from the module requires users to pull the locking tab in an opposite direction from the sensor then slide the sensor out of the module. To install the sensor position its tabs exactly on the module assembly slots before fully inserting it into place with the tabs secured and then attach the fuel level sensor electrical connector to the module. You must install the primary fuel tank module at the end of your work.

The right side Fuel Level Sensor replacement process begins by removing the right fuel tank pump module while avoiding strain on its wires. Before removal of the electrical connector you must push the locking tab forward while being cautious to avoid contact with the resistor circuit board. Disengage the locking tab on the Fuel Level Sensor through pushing inward after which you can lift the sensor until it reaches the stationary lock for removal. The new Fuel Level Sensor should be positioned into its place without pressing on electrical terminals then lowered until the locking tab gains a secure lock while verifying the connector's locking tab fully integrates into the flange. Complete the installation by attaching the Fuel Level Sensor electrical connector followed by reinstallation of the right fuel tank pump module.

Inspect the lock ring for damage; if it is warped beyond 0.41 mm (0.016 in), replace it.
