Joe, your 161-1705 pressure sensor is connected to group of five 5 Volt sensors that includes
Atmosphere Pressure Sensor, Engine Oil Pressure Sensor, Fuel Pressure Sensor, Injection
Actuation Pressure Sensor, turbocharger boost Pressure Sensor.
The troubleshooting procedures for the diagnostic codes of each pressure sensor are identical.
The engine control module sends a 5 Volt supply to terminal A of each sensor ( location on
Top of sensor wide part pin A left side ), the sensor common connection is connected to
Terminal B of each sensor ( location on top wide part pin B right side ). The signal voltage
From terminal C of each sensor ( location on lower part of sensor female plug. ) is sent to
the J2/P2 ECM connection. Location of J2/P2 connection on ECM front side of ECM looking
from rear of engine to front. Dave Atherton Retired Cat Mechanic
