3. Install the sensor with the appropriate shim.
Tighten the capscrew retaining the sensor to
proper specification.

Figure 333 — Engine Speed Sensor
ENGINE POSITION SENSOR
Installation of this sensor (Figure 334) is the
same as that for the engine speed sensor except
for the first step. When installing the engine
position sensor, make the shim calculation
measurement from the sensor mounting surface
on the front timing gear cover to the face of the
camshaft gear.
Do not measure into one of the sensing holes in
the gear face or an inaccurate measurement will
result.

OTHER ENGINE-MOUNTED SENSORS
The remaining engine-mounted sensors are
thread-mounted and are not adjustable. These
include the Fuel Temperature, Boost Air
Temperature, Boost Pressure Sensor, Coolant
Temperature, Oil Temperature and Oil Pressure
sensors. Refer to the Torque Specifications for
Engine-Mounted Sensors in the
SPECIFICATIONS section for thread sizes and
torque specifications.
Do not use an E7 English pipe-thread sensor in
place of a metric straight-thread sensor (or vice
versa). Doing so will result in thread damage to
both the sensor and the tapped hole into which
the sensor is installed.
Electronic Unit Pump (EUP)
Calibration
[221 GP]
Whenever an electronic unit pump(s) is replaced
in an engine, it is necessary to recalibrate the
pump(s) by entering the calibration code into the
engine electronic control unit (EECU). The
calibration code is a four-digit number that can be
found on the data plate of each individual unit
pump. This calibration code is then entered by
using a personal computer that is running the
V-MAC
®
Service Support Software or the
Pro-Link
®
9000.
The four-digit calibration code can be found on
the EUP data plate, shown after the letters “CAL”
for early production EUPs. For later-production
EUPs, the calibration code is still found in the
same location on the data plate (next to the word
MACK), only the identification letters “CAL” have
been eliminated to provide room for larger bar
codes.
