The NGK NTK Lambda Sensor (94355) is designed for automotive technicians and DIY vehicle owners seeking to maintain optimal engine performance and emissions standards in compatible Citroen and Peugeot vehicles. As a high-quality, heated, switching-type oxygen sensor, it provides precise monitoring of exhaust gases to ensure the engine runs at peak efficiency. While it is a robust replacement part, users must verify exact vehicle compatibility before installation to avoid incorrect sensor readings or fitment issues.

It measures the amount of oxygen in the exhaust gases to help the engine control unit adjust the air-fuel ratio for optimal combustion.
It is designed to be installed upstream, specifically before the catalytic converter.
The wire length for the 94355 model is 540 mm.
Yes, always hold the sensor by the metal body. Avoid touching the ceramic tip at the end as oils from your skin can contaminate the sensor.
No, this is a vehicle-specific part designed for select Citroen and Peugeot models. Always check compatibility before purchase.
Clear the diagnostic trouble codes (DTC) from the vehicle ECU using an OBD-II scanner after the new sensor is installed.
Inspect the wiring harness for signs of melting or breakage and ensure the electrical connector is fully seated and free of moisture or corrosion.
To install this sensor, ensure the engine is completely cool to avoid thermal burns and to prevent damage to the exhaust manifold threads. Use a dedicated oxygen sensor socket to prevent damaging the housing. It is critical to verify the MPN 94355 against your vehicle's service manual or parts catalog for your specific Citroen or Peugeot model, as even slight variations in build dates can affect fitment. When installing, apply a small amount of anti-seize compound to the threads if none is pre-applied, but strictly avoid getting any lubricant on the sensor tip, as this will cause premature failure. Always handle the unit by the body rather than the wires to maintain electrical integrity.
