Used Fiat Scudo Lambda Sensor

The Fiat Scudo has been sold almost exclusively with diesel engines in the UK, and diesel engines do not use lambda sensors in the same way petrol engines do — they typically use a wideband air-fuel ratio sensor or NOx sensor rather than a traditional lambda sensor, and many diesel variants have no upstream lambda sensor at all. If you are chasing an emissions or engine management fault on a diesel Scudo, what you are most likely looking for is an exhaust gas temperature sensor, a NOx sensor, or a mass airflow sensor rather than a lambda sensor. Confirm the exact sensor fitted to your vehicle with a breaker using your registration number before ordering anything.

The second-generation Fiat Scudo ran from 2007 onwards and diesel variants across this range do not use a traditional lambda sensor, so sourcing one by year is unlikely to be the right approach for a diesel Scudo. The emissions sensors that are fitted — such as NOx or exhaust gas temperature sensors — can vary between Euro 4 and Euro 5 specification engines, with Euro 5 introduced around 2011, so crossing that boundary means the sensors may differ. Check the exact sensor type and engine code with a breaker against your registration rather than searching by year alone.

For emissions-related sensors on the Scudo, trim level makes no difference to fitment — the relevant factors are the engine code and the emissions standard the vehicle was built to, not whether it is a Worker, SX, or Professional specification. You can disregard trim when searching, but do confirm the engine code and Euro emissions level with the breaker, as those determine which sensor assembly is correct.

Petrol-engined Fiat Scudos were sold in some markets but were extremely rare in the UK, where the overwhelming majority were diesel; if you do have a petrol variant it would have a lambda sensor as standard, but you should verify this with a breaker using your registration as petrol Scudo parts are uncommon in the UK dismantling trade.

On a diesel Fiat Scudo, the sensors most commonly involved in emissions faults are the exhaust gas temperature (EGT) sensor, the NOx sensor, the diesel particulate filter (DPF) pressure sensor, or the mass airflow (MAF) sensor — not a lambda sensor in the traditional sense. The correct part will depend on your engine code and the emissions standard of your vehicle, so give a breaker your registration and the fault code from a diagnostic scan to identify exactly what is needed.
