The Honda L15Z3 is a 1,497 cc, inline‑three naturally aspirated petrol engine produced between 2014 and 2020. It features port fuel injection, dual overhead camshafts (DOHC), and i-VTEC variable valve timing. This compact engine delivers 88 kW (120 PS) and 145 Nm of torque, with i-VTEC enabling a broad, efficient powerband for responsive urban and highway driving.
Fitted primarily to the third-generation Jazz/Fit (GE) and the second-generation City (GM) across global markets, the L15Z3 was engineered for fuel efficiency, low emissions, and smooth, linear power delivery. Emissions compliance was achieved through optimized combustion and a close-coupled catalytic converter, allowing it to meet stringent Euro 5 and later standards.
One documented concern is premature wear of the VTC (Variable Timing Control) actuator, which can cause rattling noises on cold start and trigger diagnostic trouble codes. This issue, referenced in Honda Service Bulletin 14-078, is often linked to oil quality or infrequent oil changes. Honda addressed this with revised actuator assemblies for affected model years.

Production years 2014–2016 meet Euro 5 standards; 2017–2020 models comply with Euro 6b/c depending on market (VCA UK Type Approval #VCA/HON/9101).
The Honda L15Z3 is a 1,497 cc inline‑three naturally aspirated petrol engineered for subcompact hatchbacks and sedans (2014-2020). It combines port fuel injection with i-VTEC variable valve timing to deliver smooth, linear power and excellent fuel economy. Designed to meet Euro 5 and Euro 6 standards, it balances urban agility with highway refinement.

The i-VTEC system provides a smooth, linear power delivery ideal for city driving but demands regular oil changes with Honda 0W-20 specification to ensure proper VTC actuator function. Extended oil change intervals or poor-quality oil can lead to VTC actuator wear, causing cold-start rattle and potential engine codes per Honda SIB 14-078. The engine is very fuel-efficient under normal driving conditions. For high ambient temperatures, Honda approves 5W-30 oil.
Oil Specs: Requires Honda 0W-20 specification (Honda SM 15Z3-SM). 5W-30 is approved for high-temperature conditions.
Emissions: Euro 5 certification applies to 2014-2016 models; Euro 6b/c for 2017-2020 (VCA Type Approval #VCA/HON/9101).
Power Ratings: Measured under SAE J1349 standards. Peak output requires 95 RON fuel (Honda TSB 14-078).

The Honda L15Z3 was used exclusively in Honda's GE/GM platforms with transverse mounting. This engine received no major platform-specific adaptations, but from 2017 the updated models incorporated minor ECU and emissions hardware revisions to meet Euro 6 standards, creating a software distinction. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Honda SM 15Z3-SM). The 8th VIN digit for Jazz/Fit is typically 'G'; for City, it varies by market. Visually, the L15Z3 is identifiable by its black plastic valve cover and compact, transverse layout. Critical differentiation from the L15A7: L15Z3 is an i-3 with i-VTEC, while L15A7 is an i-4 with standard VTEC. Software and some sensors are not interchangeable between pre-2017 (Euro 5) and post-2017 (Euro 6) models (Honda TSB 14-078).
The L15Z3's primary reliability risk is VTC actuator wear, with elevated incidence in vehicles subjected to infrequent oil changes. Honda service data indicates a notable failure rate before 100,000 km in affected batches, while owner reports frequently cite issues after extended service intervals. Poor oil quality or infrequent changes increases actuator wear, making adherence to the maintenance schedule critical.
