Attention! Wait until the engine has completely cooled down before starting this procedure.
Models with a four-cylinder engine
Note. The knock sensor is located on the underside of the cylinder block. You have to remove the intake manifold to access it.
1. Disconnect the ground wire from the battery (see paragraph 1 of chapter 5).
2. Remove intake manifold (see chapter 2A).
3. Disunite an electric socket of the gauge of a detonation.
4. Turn away a nut of fastening of the gauge and remove the gauge.
5. When installing the sensor, tilt the electrical terminal of the sensor slightly below horizontal. Installation is carried out in the reverse order of removal. Tighten the sensor mounting nut securely to the specified torque as specified in Specifications at the beginning of this chapter.
Models with V6 engine
Note. Knock sensors are located in the opening between the cylinder heads. You have to remove the intake manifold to access them.
6. Disconnect the ground wire from the battery (see paragraph 1 of chapter 5).
7. Remove the upper and lower intake manifolds (see chapter 2B) and coolant connecting hose (rice. 5.23 in chapter 2B).
8. Disconnect the electrical connectors of the knock sensors (fig 7.8).
Pic. 7.8. To remove any of the knock sensors (A) click on the blocking ledge (IN) on the electrical connector and disconnect the electrical connector, then unscrew the sensor (1999-2083 variant shown; on models 2084 and later, the sensor is secured with a nut)
9. On models 1999-2003 unscrew the sensors (pic. 7.8). On 2004 and later models, remove the sensor mounting nuts.
10. When installing sensors on 2004 and later models, tilt the sensor electrical terminals slightly below horizontal. Installation is carried out in the reverse order of removal. Tighten the sensors or sensor mounting nuts to the prescribed torque specified in Specifications at the beginning of this chapter.
