The Honda P10A2 is a 988 cc, inline‑three turbocharged petrol engine produced between 2019 and 2023. It features direct injection, a single — scroll turbocharger, and dual overhead camshafts (DOHC). This compact powerplant delivers 90 kW (122 PS) and 173 Nm of torque, with VTEC technology enabling a responsive powerband for urban agility and highway overtaking.
Fitted primarily to the second — generation HR — V (RV) and the fourth — generation Fit/Jazz (GR) across global…

All production years (2019–2023) meet Euro 6d-TEMP or Euro 6d standards depending on market (VCA UK Type Approval #VCA/HON/7890).
The Honda P10A2 is a 988 cc inline‑three turbocharged petrol engineered for subcompact SUVs and hatchbacks (2019-2023). It combines direct fuel injection with VTEC variable valve timing to deliver high specific output and a linear power curve. Designed to meet Euro 6d emissions standards, it balances efficiency with spirited performance.

The Honda P10A2 was used exclusively in Honda's GR/RV platforms with transverse mounting. This engine received no major platform-specific adaptations, but software calibrations were optimized for the HR-V's weight versus the Fit/Jazz. All adaptations are documented in OEM technical bulletins.
The P10A2's primary reliability risk is high-pressure fuel pump cam follower wear, with elevated incidence in vehicles subjected to infrequent oil changes. Honda service data indicates a notable failure rate before 60,000 km in affected batches, while owner reports frequently cite issues after missed services. Poor oil quality or incorrect viscosity increases wear, making adherence to the maintenance schedule and oil specification critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The P10A2 is generally robust, but its main concern is the HPFP cam follower, which can wear prematurely if oil changes are neglected. With proactive maintenance—using the correct 0W-20 oil and changing it on schedule—it can be very reliable for 150,000+ km. The timing chain is designed to last the engine's lifetime.
The most frequent issues are HPFP cam follower wear, carbon buildup on intake valves (common to direct-injection engines), and GPF clogging from short trips. A less common issue is turbo wastegate rattle on early units. These are documented in Honda service bulletins.
The P10A2 was used in the second-generation Honda HR-V (RV chassis, 2019-2023) and the fourth-generation Honda Fit/Jazz (GR chassis, 2019-2023) globally. It was marketed as the 1.0 VTEC Turbo in both models.
Yes, the P10A2 responds well to tuning. A simple ECU remap (Stage 1) can safely yield 140-150 PS. With supporting mods like an intake and intercooler (Stage 2), outputs of 160-170 PS are achievable. The stock internals are strong, but pushing beyond 180 PS may require internal upgrades.
Official combined figures are excellent, typically around 5.5-6.0 L/100km (47-51 mpg UK) for the Fit/Jazz and 6.0-6.5 L/100km (43-47 mpg UK) for the HR-V. Real-world economy is very good: expect 6.5-8.0 L/100km (35-43 mpg UK) in mixed driving, and 5.0-5.5 L/100km (51-56 mpg UK) on steady highway runs.
Yes. Like virtually all modern Honda engines, the P10A2 is an interference design. If the timing chain were to fail (which is extremely rare), the pistons would collide with the valves, causing catastrophic engine damage. Fortunately, the chain is very durable.
Honda strictly recommends 0W-20 synthetic oil for the P10A2. This specific viscosity is critical for protecting the HPFP cam follower and ensuring proper VTEC operation. No alternative viscosities are approved by Honda for this engine.
