Which car has a D17A2 engine?

The D17A2 engine came in the 2001–2005 Honda Civic EX in the United States and in equivalent VTEC-equipped trims such as the Canadian-market Civic Si. In broader terms, it’s the 1.7-liter SOHC VTEC engine found in seventh-generation Civic sedans and coupes (chassis codes ES/EM2), excluding performance variants like the U.S.-market Civic Si hatchback, which used a different engine.

What the D17A2 is

The D17A2 is a 1.7-liter, single overhead cam (SOHC) VTEC inline-four from Honda’s D-series family. In North American Civics, it produced around 127 hp (95 kW) and was tuned for a balance of everyday drivability and efficiency rather than high-rev performance. It’s distinct from the economy-focused D17A6 (VTEC-E) and the non-VTEC D17A1 used in lower trims.

Vehicles that used the D17A2

The following list covers the primary models and trims that were factory-equipped with the D17A2, focusing on mainstream North American applications and their closest market equivalents.

• 2001–2005 Honda Civic EX (U.S.) — sedan and coupe, SOHC VTEC (D17A2)
• 2001–2005 Honda Civic Si (Canada) — sedan and coupe, trim equivalent to U.S. EX, SOHC VTEC (D17A2)
• Select seventh-generation Civic “VTEC” trims in other markets — badged as VTi/VTi-S in some regions, typically sharing the D17A2 specification

Notably, the 2002–2005 U.S.-market Civic Si hatchback (EP3) did not use the D17A2; it featured the K20A3 engine. Base U.S. trims (DX/LX/VP) used the D17A1, while the fuel-economy HX variant used the D17A6.

How to confirm your car has a D17A2

If you’re unsure which engine your Civic carries, you can verify it with a few quick checks. These steps help distinguish the D17A2 from other D17 variants and ensure parts compatibility.

1. Check the engine code stamped on the block: look on the front of the engine, below the cylinder head near the exhaust manifold; it will read “D17A2.”
2. Consult the under-hood emissions label: it often indicates the engine family and can point to the correct variant.
3. Review the owner’s manual or original window sticker: trim/engine pairings are usually listed.
4. Decode the VIN with a Honda-specific decoder or dealer: they can confirm the factory-installed engine and trim.

Confirming the exact engine code is especially important when ordering parts such as timing components, sensors, and gaskets, as D17 variants are similar but not always interchangeable.

Why the D17A2 application matters

Knowing that the D17A2 is tied to seventh-generation Civic EX-equivalent trims helps owners and buyers source the correct maintenance parts, ECU calibrations, and service procedures. It also clarifies performance expectations and distinguishes this engine from both economy-focused variants and higher-output K-series engines used in sport models.

Related D17 variants (for context)

Honda offered several D17 variants during the 2001–2005 Civic generation. Understanding their roles can prevent mix-ups when searching for parts or service information.

• D17A1 — non-VTEC engine used in U.S. DX/LX/VP trims
• D17A6 — VTEC-E (lean-burn, economy) engine used in the U.S. HX
• D17A7/D17A8 — market-specific variants tied to natural-gas or regional specifications (availability varies by region)

While these engines share displacement and many components, calibration and hardware differences mean you should always verify the exact code before purchasing parts or planning modifications.

Summary

The D17A2 is the SOHC VTEC 1.7-liter engine found primarily in the 2001–2005 Honda Civic EX (U.S.) and equivalent VTEC trims such as Canada’s Civic Si. It distinguishes those models from non-VTEC and economy-focused variants and from K-series-powered performance Civics of the same era.

What Hondas have a D series engine?

The Honda D-series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra. Engine displacement ranges between 1.2 and 1.7 liters. The D series engine is either SOHC or DOHC, and might include VTEC variable valve lift.

How much horsepower does a d17a engine have?

Power Output: Typically produces around 110 to 130 horsepower, depending on the specific variant. 3. Torque: Delivers approximately 100-110 lb-ft of torque.

Can you tune a D17A2?

Important: An HA Motorsports KTuner jumper harness, and custom cam gear are required to use this ECU package and are sold separately. This setup combines to allow tuning your D17A1 or D17A2 engine via the KTuner software!

What cars had the D17A2?

2001-2005 Honda Civic EX LX DX D17a2 1.7L SOHC VTEC engine. This motor was imported from Japan with low miles and would be a great replacement for your 2001-2005 Honda Civic. The D17a2 outperforms its predecessor (the d17a1) because of the new VTEC system.
