3 Release the retaining clip (1), two places, attaching
the air cleaner upper housing (2) to the air cleaner
lower housing (3).
4 Rotate the upper housing in the direction of the arrow and withdraw the housing while disengaging the two
outer retaining lugs (4).
5 If necessary, remove the air cleaner element (5).
Figure 6C1-3 – 3
Reinstall
Reinstallation of the air cleaner upper housing is the reverse of the removal procedure, noting the following:

Ensure the air cleaner sealing rubber is
correctly located in the air cleaner lower
housing. Failure to do this may result in
engine damage due to unfiltered air entering
the engine intake system.
1 Reinstall the air cleaner element.
2 Reinstall the air cleaner upper housing aligning the outer retaining lugs.
3 Reinstall the air cleaner upper housing ensuring the upper housing retaining clips are correctly located.
4 Road test the vehicle and check for correct operation, taking particular note that no air leaks are evident.
Air Cleaner Lower Housing Assembly
Remove
1 Turn the ignition switch off.
2 Remove the air cleaner upper housing as described previously.

3 Using a suitable lever, gently lever the locking tangs
(1) of the lower housing insulator sleeve back to clear
the lower housing retaining bolt (2). Repeat this
process for each of the remaining two sleeves.
4 Remove the three bolts retaining the lower housing (3) to the fender inner panel and remove the housing.
5 If required, remove the insulator sleeve and air cleaner lower housing insulator (4).
Figure 6C1-3 – 4

Reinstall
1 Reinstall the air cleaner lower housing attaching bolt and tighten to the correct torque specification.
Air cleaner lower housing attaching
bolt torque specification ..........................18.0 – 22.0 Nm
2 Using a suitable hammer and pin punch, position the locking tang against the bolt head.
3 Road test the vehicle and check for correct operation.
2.3 Barometric Pressure Sensor
Remove
1 Turn the ignition switch off.
2 Disconnect the wiring harness connector (1) from the barometric pressure (BARO) sensor (2).

3 Remove the bolt (1) attaching the BARO sensor (2) to
the upper intake manifold (3).
4 Remove the BARO sensor from the manifold by first, twisting the sensor to release it, and then pulling it
upwards to remove it.
Figure 6C1-3 – 6
Reinstall
Reinstallation of the barometric pressure (BARO) sensor is the reverse of the removal procedure, noting the following:

Ensure the BARO sensor is fully seated
before tightening the attaching bolt to the
specified torque.
1 Reinstall the BARO sensor bolt and tighten to the correct torque specification. Barometric pressure sensor
attaching bolt
torque specification ...................................8.0 – 12.0 Nm
2 Road test the vehicle and check for correct operation.
2.4 Camshaft Position Sensor
Remove
1 Turn the ignition switch off.

2 Disconnect the wiring harness connector (1) from the CMP sensor (2).

Clean the area around the CMP sensor before
removal to avoid debris from entering the
engine.
3 Remove the CMP sensor attaching bolt (1).
4 Remove the CMP sensor (2) by first twisting the sensor to release it, and then pulling it away from the
front engine cover to remove it.

Figure 6C1-3 – 8
Reinstall
Reinstallation of the camshaft position (CMP) sensor is the reverse of the removal procedure, noting the following:
1 Lubricate the CMP sensor O-ring with clean engine oil.
2 Reinstall the CMP sensor by pushing in on the sensor to engage the sensor O-ring in the front engine cover.

Ensure the CMP sensor is fully seated before
tightening the attaching bolt to the specified
torque.
3 Reinstall the CMP sensor bolt and tighten to the correct torque specification. Camshaft position sensor attaching bolt
torque specification ...................................8.0 – 12.0 Nm
4 Road test the vehicle and check for correct operation, taking particular note there is no engine oil leak from the CMP sensor.
2.5 Crankshaft Position Sensor
Remove
1 Turn the ignition switch off.
2 Raise the front of the vehicle and support on safety stands, refer to 0A General Information for location of the jacking points.

Test

To prevent component and damage use
connector test adaptor kit J 35616-A.
Resistance Check

1 Connect a digital ohmmeter using connector test adaptor kit J 35616-A to the crankshaft position (CKP)
sensor.
2 Measure the resistance across terminals 1 and 2.
3 Compare the reading against the specification.
CKP sensor resistance @ 20°C ................ 850 – 1040 Ω
4 If the resistance is not within specification, replace the
CKP sensor.
