Opel Frontera UE. Manual - part 1551

 

 

6E–419

6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

On Vehicle Service  Crankshaft

Position (CKP) Sensor

Removal Procedure

1. Disconnect the negative battery cable.
2. Disconnect the electrical connector to the CKP

sensor.

3. Remove one bolt and the CKP sensor from the right

side of the engine block, just behind the mount.

NOTE: Use caution to avoid any hot oil that might drip
out.

TS22909

Inspection Procedure

1. Inspect the sensor O-ring for cracks or leaks.
2. Replace the O-ring if it is worn or damaged.
3. Lubricate the new O-ring with engine oil.
4. Install the lubricated O-ring.

Installation Procedure

1. Install the CKP sensor in the engine block.
2. Install the CKP sensor mounting bolt.

Tighten

D

Tighten the mounting bolt to 9 N·m (78 lb in.).

TS22909

3. Connect the electrical connector to the CKP sensor.
4. Connect the negative battery cable.

Engine Coolant Temperature

(ECT) Sensor

Removal Procedure

NOTE: Care must be taken when handling the engine
coolant temperature (ECT) sensor.  Damage to the ECT
sensor will affect proper operation of the fuel injection
system.

1. Disconnect the negative battery cable.
2. Drain the radiator coolant.  Refer to 

Draining and

Refilling Cooling System in Engine Cooling section.

3. Disconnect the electrical connector.

4. Remove the ECT sensor from the coolant crossover.

014RY00002

Installation Procedure

1. Apply sealer or the equivalent to the threads of the

ECT sensor.

2. Install the ECT sensor in the coolant crossover.

Tighten

D

Tighten the ECT sensor to 30 N·m (22 lb ft.).

4. Fill the radiator with coolant.  Refer to 

Draining and

Refilling Cooling System in Engine Cooling section.

5. Connect the negative battery cable.

Heated Oxygen Sensor (HO2S)

Removal Procedure

1. Disconnect the negative battery cable.
2. Locate the two oxygen sensors.

D

Bank 1 sensor 1 is mounted on the exhaust pipe
ahead of the right-hand catalytic converter.

TS22912

D

Bank 2 sensor 1 is mounted on the exhaust pipe
ahead of the left-hand catalytic converter.

TS22914

3. Disconnect the pigtail from the wiring harness.

060RY00128

IMPORTANT:

The pigtail is permanently attached to

the sensor.  Be careful not to pull the wires out.

NOTE: Do not use a torch to remove an HO2S unless the
sensor is being replaced.  Using a torch could damage the
sensor.

4. Remove the sensor from the exhaust pipe.

D

Because of the expansion and contraction of the
metal in the exhaust system over time, this may be
difficult if the engine temperature is below 48

°

C

(120

°

F).

6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Inspection Procedure

All four sensors are identical.  Inspect each in the same
way.

1. Inspect the pigtail and the electrical connector for

grease, dirt, corrosion, and bare wires or worn
insulation.

2. Inspect the louvered end of the sensor for grease,

dirt, or other contaminations.

060RY00128

Installation Procedure

IMPORTANT:

D

There is a special anti-seize compound on the HO2S
threads.  This compound consists of glass beads
suspended in a liquid graphite solution.  The graphite
burns away with engine heat, but the glass beads will
remain, making the sensor easier to remove.

D

New or service sensors will already have the
compound applied to the threads.  If a sensor is
removed and is to be reinstalled for any reason, the
threads must have anti-seize compound applied.

1. Apply anti-seize compound or the equivalent to the

threads of the oxygen sensor, if necessary.

2. Install the oxygen sensor on the exhaust pipe in its

original position.

Tighten

D

Tighten the oxygen sensor to 55 N·m (40 lb ft.).

3. Connect the pigtail to the wiring harness.
4. Connect the negative battery cable.

Intake Air Temperature (IAT)

Sensor

Removal Procedure

1. Disconnect the negative battery cable.
2. Remove the engine cover
3. The IAT sensor is located in the intake air duct, behind

the throttle body.

4. Disconnect the electrical connector from the IAT

sensor.

TS23741

5. Remove the IAT sensor from the intake air duct by

using a rocking motion while pulling the sensor.
