DTC 44: RH Primary Crash Sensor Not Mounted Properly

Electrical Schematic:

Normal Operation
The diagnostic monitor measures the resistance between Pin 20 (Circuit 618, P/LG) and Pin 3 (diagnostic monitor reference ground). If the diagnostic monitor measures a difference of more than 2.0 ohms between Pin 20 and Pin 3, it will flash out Diagnostic Trouble Code 44.

Note that Circuit 618 (P/LG) is attached to the side of the RH primary crash sensor case. In addition, the case is grounded to the vehicle.

Possible Causes
High resistance on Pin 20 (Circuit 618, P/LG) to ground can be caused by:
1. A poor connection due to loose mounting, dirt, or corrosion at the RH primary crash sensor mounting location.
2. An open or damaged wire in Circuit 618 (P/LG) from Pin 20 of the diagnostic monitor harness connector to RH primary crash sensor.
3. An open circuit inside RH radiator primary sensor.
