REPAIR INSTRUCTIONS, PART 2
Make sure that the seals are firmly seated on the
connectors and that the EECU terminal pins are
straight and not damaged.
앫 EJ2 (89-pin connector) — Lift the locking
lever to the full-open position and place the
connector in position squarely over the
module terminals. Push the connector into
the module until firmly seated. Then, close
the locking lever to secure the connection.
DO NOT use the locking lever to seat the
connector.
앫 EJ1 (36-pin connector) and EJ3 (16-pin
connector) — Lift the metal locking lever to
the full-open position and place the
connector in position squarely over the
module terminals. Push the connector into
the module until firmly seated. And last,
push down on the center crosspiece of the
lever to close and secure the connection.
DO NOT apply pressure to the outer edges
of the locking lever which then can be bent
and fail to secure the connection.
Sensors Installation and
Adjustment
ASET™ AC ENGINE SENSORS
The engine speed and engine position sensors
are adjustable following the procedures covered
in the ENGINE SETUP AND ADJUSTMENTS
section. The remaining engine-mounted sensors
are thread-mounted and are not adjustable. Refer
to “Torque Specifications” for engine-mounted
sensors in the SPECIFICATIONS section for
thread sizes and torque specifications. The
following is a list of the thread-mounted sensors:
앫 Oil pressure sensors
앫 Oil temperature
앫 Coolant temperature
앫 Boost pressure
앫 Boost air temperature
앫 Fuel temperature
앫 Air Temperature/Humidity Sensor
앫 Compressor Discharge Temperature Sensor
앫 CMCAC Outlet Temperature Sensor
앫 Inlet Manifold Temperature Sensor
앫 VTG Position Sensor
앫 VTG Wheel-Speed Sensor
The EGR Temperature and EGR MASS Flow
sensors, however, are an integral part of the
upper EGR gas tube and are not serviceable as
separate items. If replacement is required, the
upper EGR gas tube must be replaced along with
the EGR MASS Flow module to maintain proper
system calibration.
