Removal and installation of the crankshaft position sensor
− Remove the lower timing belt cover before starting to remove the parts.
− When removing parts, refer to the figure "Removing the crankshaft position sensor".
Removing the crankshaft position sensor.
− Installation of parts is carried out in the reverse order of removal.
− After completing the installation of the parts, install the lower timing belt cover.
Removal and installation of the camshaft position sensor
− (GDI engines) Before removing parts, remove the decorative engine cover.
− When removing parts, refer to the figure "Removing the camshaft position sensor".
Removing the knock sensor.
− Installation of parts is carried out in the reverse order of removal.
− (GDI engines) After installing the parts, install the decorative engine cover.
Removal and installation of the knock sensor
− (GDI engines) Before removing parts, remove the decorative engine cover.
− (MPI engine) Before removing parts, disconnect the wires from the battery terminals.
− When removing and installing parts, refer to the figure "Removing the knock sensor".
Removing the camshaft position sensor.
− When removing parts, pay attention to the following operations:
1. (Engine 4G15-GDI) Removing the intake manifold resonator.
Loosen the intake manifold resonator mounting bolts at the locations shown in the figure and remove it.
2. Removing the knock sensor.
Using the special tool, remove the knock sensor as shown in the illustration.
Caution: Do not drop or subject the knock sensor to impact.
− When installing the parts, pay attention to the installation procedure of the knock sensor.
A) Using the special tool, install the knock sensor as shown (see sensor removal procedure).
b) When installing the knock sensor, make sure that the sensor tightening torque corresponds to the nominal value, since the installation of the sensor affects the operation of the engine management system.
Tightening torque - 21-25 Nm
− After completing the installation of the parts, perform the following operations:
- A) (GDI engines) Install the decorative engine cover.
- b) (MPI motors) Connect the wires to the battery terminals.
