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.

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.

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.

3

Disconnect the wiring harness connector (1) from the
crankshaft position (CKP) sensor (2).

Figure 6C1-3 – 9

Clean the area around the CKP sensor before
removal to avoid debris from entering the
engine.

4

Remove the CKP sensor attaching bolt (1).

5

Remove the CKP sensor (2), by first twisting the
sensor to release it, and then pulling it away from the
engine block to remove it.

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.

Reinstall

Reinstallation of the crankshaft position (CKP) sensor is the reverse of the removal procedure, noting the following:

1

Lubricate the CKP sensor O-ring with clean engine oil.

2

Reinstall the CKP sensor by pushing down on the sensor to engage the sensor O-ring in the engine block.

Ensure the CKP sensor is fully seated before
tightening the attaching bolt to the specified
torque.

3

Reinstall the CKP sensor bolt and tighten to the correct torque specification.
