Cheap Hyundai Kona Lambda Sensor

Yes, petrol-engined Kona models are fitted with lambda sensors (also called oxygen sensors) as part of their exhaust emissions system — typically one upstream of the catalytic converter and one downstream. These sensors are standard on petrol engines to manage the air-fuel mixture and monitor catalyst efficiency. Diesel Kona models do not use a conventional lambda sensor in the same way, so confirm your fuel type before searching.

The Hyundai Kona first generation ran from 2017 to 2023, with a facelift introduced for the 2021 model year, so there is a production boundary around 2021 that could affect sensor compatibility even within the same generation. If the engine code is identical across both cars, the lambda sensor may well be the same part, but you should confirm the exact engine code and sensor position (upstream or downstream) with the breaker against your registration before buying. A sensor from the wrong emissions calibration or connector type will cause running problems and potentially a failed MOT.

Trim level does not affect lambda sensor fitment on the Kona — SE, SE Connect, Premium, N Line, and Ultimate trims all use the same sensor for a given engine and emissions standard. What matters is the engine code and whether the car is Euro 6 compliant, not the interior or cosmetic specification. When speaking to a breaker, give them your registration and engine code rather than your trim name.

No — the 1.0 T-GDi and 1.6 T-GDi are different engines with different exhaust configurations, so their lambda sensors are unlikely to be interchangeable. Always match by engine code (for example G3LC for the 1.0-litre or G4FJ for the 1.6-litre) and sensor position, not just engine capacity or body style. Give the breaker your full registration so they can pull the exact spec.

No — the Hyundai Kona Electric has no internal combustion engine and therefore no exhaust system, catalytic converter, or lambda sensor. If you drive a Kona Electric and are seeing a related fault code, it is worth speaking to a Hyundai specialist, as the fault is unlikely to be a lambda sensor. Lambda sensors are only relevant to the petrol-engined Kona variants.

Lambda sensors are specific to petrol engines on the Kona, and diesel models with a DPF use different exhaust aftertreatment technology entirely, so a DPF-equipped diesel donor car is not a relevant source for a petrol lambda sensor. Within petrol variants, the key boundaries are the engine code and the Euro emissions standard the car was built to, and a sensor from a different emissions era may not be calibrated correctly even if it physically fits. Confirm all of this with the breaker against both registrations before purchasing, as this is strong confirm-with-breaker territory.
