Removing the knock sensor in a Ford Focus 2 car

Tools:

• Collar for end nozzle
• Nozzle on the crank 10 mm
• Open-end wrench 13 mm

Notes:

We remove the knock sensor for replacement and when repairing the engine.

Knock sensors on engines 1.4 and 1.6 l R4 Duratec 16V, as well as 1.6 l R4 16V Duratec Ti-VCT are screwed into the wall of the cylinder block in its upper part, under the intake manifold in areas between the 1st and 2nd m, as well as the 3rd and 4th cylinders. On engines 1.8 and 2.0 l R4 Duratec-HE 16V, the knock sensor is installed in the area between the 2nd and 3rd cylinders on the left side of the engine.

1.  Disconnect the wire from the negative terminal of the battery.

2.  Remove the intake manifold as described here.

3. By pressing the latch, we disconnect the blocks of the wiring harness of the engine management system and the wiring harness of the knock sensor.

4. Using the “10” head, unscrew the bolt securing the sensor to the cylinder block and remove the sensor.

5. Install the knock sensor in reverse order.

Notes:

Before installing the sensor, clean the surface of the cylinder block at the sensor installation site.
