Installing lambda probe

When installing, note the following points:

Notes:

  • ◆ When installing, the lambda probe wire must be secured in exactly the same position as before in order to avoid contact between the wire and the exhaust pipe.
  • ◆ The screw thread on the lambda probe is coated with a special paste (high-temperature lubricant). This paste must not be allowed to penetrate the openings on the probe.
  • ◆ Tightening torque: 50 Nm.
