INTAKE AIR TEMPERATURE
SENSOR
DESCRIPTION
The boost pressure sensor/intake air temperature
sensor is located in the top of the intake manifold
(Fig. 6). The intake air temperature sensor is used to
measure the intake air temperature. The intake air
temperture sensor is a dual purpose sensor. It is also
used as a boost pressure sensor.
OPERATION
The intake air temperature sensor is a negative
temperature coefficient (NTC) thermistor (resistance
varies inversly with temperature). This means at
cold air temperature its resistance is high, sothe volt-
age signal will be high. As intake air temperature
increases, sensor resistance decreases and the signal
voltage will be low. This allows the sensor to provide
an analog voltage signal (0.2-4.8 volts) to the ECM.
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove engine cover retaining bolts and cover-
(Refer to 9 - ENGINE COVER - REMOVAL).(3) Disconnect intake air temperature electrical
connector.
(4) Remove intake air temperature sensor retain-
ing screws and sensor (Fig. 6).
INSTALLATION
(1) Install intake air temperature sensor and
retaining bolts (Fig. 6). Torque to 5.4 N´m.
(2) Connect intake air temperature sensor.
(3) Install engine cover and retaining bolts (Refer
to 9 - ENGINE COVER - INSTALLATION).
CRANKSHAFT POSITION
SENSOR
DESCRIPTION
The crankshaft position sensor is mounted in the
right rear of the engine block below the turbocharger
(Fig. 7). This sensor is used to detect engine speed.
OPERATION
The crankshaft position sensor is a magnetic
pickup type sensor that generates an ac signal. The
sensor contains a permanent magent and a coil of
wire. The sensor generates an ac signal each time a
notch in the reluctor wheel on the crankshaft passes
across the permanent magnet. The ECM calculates
engine speed based on the frequency of the ac signal.
The ECM supplies the sensor ground.

(6) Start engine and let idle just long enough to
circulate power steering fluid through the analyzer
and hoses. Shut off engine.
(7) Check power steering fluid level and add fluid
as necessary. Start engine again and let idle until the
air is out of the fluid.
(8) Gauge should read below 300 psi (2068 kPa). If
above, inspect the hoses for restrictions and repair as
necessary. The initial pressure should be in the range
of 100-275 psi (689-1896 kPa) depending on fluid
temperature. The flow meter should read above 1.5
GPM.
CAUTION: The following test procedure involves
testing maximum pump pressure output and flow
control valve operation. Do not leave valve closed
for more than four seconds as the pump could be
damaged.
NOTE: Power steering pump maximum pressure for
2.4L engines is 1,200 ± 1,350 psi (8,274 ± 9,308
kPa). Power steering pump maximum pressure for
all other engines is 1,400 ± 1,500 psi (9,653 ± 10,342
kPa).
(9) Close analyzer valve fully three times and
record highest pressure indicated each time. All three
readings must be within specifications. If any of the
three power steering pump pressures are above orbelow specifications, replace pump. (Refer to 19 -
STEERING/PUMP - REMOVAL)
CAUTION: Do not force the steering to operate
against the stops for more than 4 seconds at a time
because pump damage can result.
(10) Once the pump has been verified as working
correctly, completely open the valve on the Power
Steering Analyzer. Turn the steering wheel to the
extreme left until the stop in the steering gear is
met. Hold it there for 2±4 seconds, then release it.
Now turn the steering wheel to the right until the
right stop is met. Hold it there for 2±4 seconds, then
release it. Record the stabilized pressure at each
position. Compare the recorded readings to the spec-
ifications. If the output pressures are not within 100
psi (689 kPa) of one another against either stop or
are below specifications, the steering gear is leaking
internally and must be replaced. (Refer to 19 -
