Production years 2016–2018 meet Euro 6b standards; 2019–2023 models comply with Euro 6d-TEMP .
The Fiat 192 A3.000 – Petrol is a 1,368 cc inline-four naturally aspirated engine designed for compact crossover and MPV applications (2016–2023). It integrates MultiAir III variable valve timing with port fuel injection to enhance low-RPM torque and fuel economy. Engineered to meet Euro 6b and Euro 6d-TEMP emissions standards, it supports responsive city driving while maintaining regulatory compliance.

The Fiat 192 A3.000 – Petrol was used across Fiat's 334 platform with transverse mounting and shared with Lancia for badge-engineered variants. This engine received platform-specific adaptations-revised ECU mapping in the 500X and enhanced cooling in the 500L-and from 2019 the updated 500X Cross models adopted Euro 6d-TEMP-compliant calibration, creating emissions-based interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 192 A3.000 is generally reliable when maintained properly, but early models (2016–2018) are prone to MultiAir control unit failure. Later units (post-2019) benefit from improved components. Regular servicing, especially timely timing belt replacement, and use of 95 RON fuel significantly improve longevity. Well-maintained engines can exceed 150,000 km without major issues.
The most common issues are MultiAir control unit wear (especially pre-2019), throttle body carbon buildup, ignition coil failures, and coolant leaks from the water pump seal. These are documented in Fiat service bulletins and are largely preventable with scheduled maintenance and use of correct fluids and parts.
This engine was used in the Fiat 500X (334-series, 2016–2023) and Fiat 500L (334L, 2016–2022) in 1.4-litre form. It was also badge-engineered as the Lancia Ypsilon 1.4 Gold (2017–2021). All applications are front-wheel drive with transverse engine mounting and meet Euro 6b or Euro 6d-TEMP standards depending on model year.
Limited tuning potential exists. ECU remapping can yield modest gains (~5–8%) in throttle response and mid-range torque, but power output is constrained by the naturally aspirated design and MultiAir III system. Aftermarket intake or exhaust upgrades offer minimal benefit. Significant tuning is not recommended due to narrow powerband and valve train limitations.
In combined driving, the 192 A3.000 achieves approximately 6.2–6.8 L/100km (45–41 mpg UK). City driving may see 7.5 L/100km (38 mpg), while highway cruising can reach 5.6 L/100km (50 mpg). Real-world economy depends heavily on driving style, with stop-start urban use reducing efficiency. Fuel system requires minimum 95 RON petrol.
Yes. The 192 A3.000 is an interference engine. If the timing belt fails or jumps, the pistons can collide with open valves, causing severe internal damage. This makes adherence to the 120,000 km or 6-year replacement interval absolutely critical. Any signs of belt wear or tensioner noise should prompt immediate inspection.
Fiat specifies SAE 5W-30 viscosity oil meeting API SN/CF standards. ACEA A1/B1 compliant oils are also acceptable. Oil should be changed every 15,000 km or 12 months to maintain MultiAir actuator and valve train lubrication. Always use quality synthetic or semi-synthetic oil suitable for high-revving petrol engines.
