If the resistance is more than 0.5 ohms, clean the mating surfaces and re-measure the
resistance. Do not proceed until the resistance is less than 0.5 ohms.
7.
Connect the engine low voltage harness connectors (J3 or J4) to the pressure sensor;
orient the alignment keys of the connector with those of the sensor. Push the harness
connector on the sensor connector while twisting the lock ring clockwise. The
connector lock ring will “snap” into its final position allowing no further rotation.
When properly mated and locked, the bayonet orientation pins are observable in the
locking ring pin observation port as shown in Figure 10-45.
