The Lambda sensor is used to regulate exhaust gas composition on gasoline engines. It is screwed into the exhaust pipe upstream of the catalytic converter.

Caution: Do not repair or solder the Lambda sensor connector cables. If a cable is damaged, replace the Lambda sensor completely. Removal

  • 1.6 L engine: Remove the plastic cover on the bulkhead - 1 -. Disconnect the connector underneath for the Lambda sensor (arrow).

  • 1.4/1.8/2.0 L engines: Disconnect the connector in the Lambda sensor lead. On the 1.8 L engine, the connector is located below the throttle body.

  • Unclip the electrical lead from the cable guides.

  • Unscrew the Lambda sensor - 1 - from the front exhaust pipe.

    On the 1.4 L engine, the Lambda sensor is located farther forward on the exhaust pipe. See illustration T-2640 on page 121.

Caution: Do not touch or contaminate the tip of the sensor. Installation

  • Coat the thread of the lambda sensor with high-temperature paste, for example Bosch lambda sensor grease or Fiat anti-seize, and tighten to 55 N·m.

CAUTION: If the sensor is installed without the high-temperature special grease, the thread will seize over time. The lambda sensor can then no longer be unscrewed.

  • Route the electrical lead and connect the plug.

    On the 1.6 L engine, install the connector cover on the bulkhead.
