until you hear the hinged locking tab click in place.
Oil Pressure Sensor
Pressure sensor connectors have a single locking tab on the wiring
harness connector. The Fuel Pump Pressure Sensor, Oil Pressure
Sensor, and Manifold Pressure Sensor are shown in Figure 35. The
Fuel Rail Pressure Sensor is shown in Figure 38 and the Induction
Delta Pressure Sensor is shown in Figure 39.
Disconnect:
1. Pull or pry up on the front of the locking tab (Figure 13) to release
it from the locking feature on the sensor and pull the wiring
harness connector from the sensor (Figure 14).
