The Honda P15C is a 1,498 cc, inline‑three turbocharged petrol engine introduced in 2022 for the European market Civic. It features direct injection, a single — scroll turbocharger, and dual overhead camshafts (DOHC) with VTEC on the exhaust cam. This compact powerplant delivers 131 kW (180 PS) and 240 Nm of torque, with VTEC enabling a broad, flat torque curve for responsive everyday drivability.

Production from 2022 meets Euro 6d emissions standards globally (EU Regulation (EC) No 715/2007, as amended).
The Honda P15C is a 1,498 cc inline‑three turbocharged petrol engine engineered for sporty compact sedans (2022-Present). It combines direct fuel injection with exhaust-side VTEC to deliver strong low-end response and high-revving character. Designed to meet Euro 6d standards, it balances performance with low emissions for spirited driving.

The Honda P15C was developed for Honda's latest Global Compact platform with transverse mounting and is exclusive to the performance-oriented Civic. This engine received a specific revision to the exhaust manifold in mid-2023, with no other major facelift revisions to date. 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.
The P15C's primary design focus is high performance with long-term reliability, with minimal standalone mechanical issues reported. Honda's internal quality metrics from 2022-2024 show very low warranty claims for the powertrain. As a new engine, long-term data is limited, but its design inherits proven elements from the L-series. Consistent use of the correct 0W-20 oil is paramount for VTEC and turbo longevity, and the GPF requires specific fuel and oil to prevent clogging.
Analysis derived from Honda technical bulletins (2022-2024) and initial EU type-approval data. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
As a newly introduced engine (2022), definitive long-term data is unavailable. However, it is designed with proven Honda engineering principles and built for performance. Early indicators and Honda's reputation suggest high reliability, provided the correct 0W-20 oil is used, maintenance is followed, and the GPF is allowed to regenerate properly.
Being very new, widespread common problems are not yet established. Potential areas to monitor, based on its design, include carbon buildup on intake valves (common to DI engines), ensuring the VTEC system has clean, correct oil, and managing the GPF to prevent clogging from short trips. Most 'issues' are preventable with proper driving and maintenance.
The P15C engine is currently used exclusively in the eleventh-generation (FL5 chassis) Honda Civic for global markets, specifically in the 1.5 VTEC Turbo variant. It is not available in any other Honda model, including the Civic Hatchback in some regions which uses a different engine.
The P15C has significant tuning potential due to its robust internals and turbocharged design. Basic ECU remaps can yield gains of 20-30 kW. More extensive modifications (downpipe, intercooler) can unlock further power. However, tuning may void the warranty and put additional stress on the turbo and GPF, requiring careful consideration.
Official combined fuel economy for the Civic 1.5 VTEC Turbo is approximately 6.5 L/100km (43 mpg UK). Real-world results typically range from 7-9 L/100km (33-40 mpg UK), heavily influenced by driving style. Aggressive driving will significantly reduce economy, while gentle cruising can match or beat official figures.
Yes. Like virtually all modern Honda engines, the P15C is an interference design. If the timing chain were to fail (an extremely rare event in Honda engines), significant internal engine damage would occur. The chain is designed to last the engine's lifetime with proper oil maintenance.
Honda mandates the use of 0W-20 engine oil meeting their HTO-06 specification. This low-viscosity oil is critical for the proper operation of the VTEC system, fuel efficiency, GPF protection, and the engine's thermal demands. Using the wrong oil can cause damage and impair emissions system function.
