Honda OEM PCV (Crankcase Ventilation) Hose 17131-5R1-000 – HR-V 2016–2020 / Jazz 2018–2020 1.5 NA (L15B3/L15B4)

Honda OEM PCV (Crankcase Ventilation) Hose 17131-5R1-000 – HR-V 2016–2020 / Jazz 2018–2020 1.5 NA (L15B3/L15B4)

Genuine Honda OEM PCV / crankcase ventilation hose (pipe) with part number 17131-5R1-000. This hose is a key element of the PCV system responsible for routing crankcase vapors and keeping the intake/vacuum system properly sealed, which helps maintain stable idle, correct fuel trims and clean engine operation.

The hose is installed in the engine bay within the PCV/breather circuit – between the crankcase ventilation components (around the valve cover / PCV valve area) and the intake (intake manifold or intake duct depending on the version). For 100% certainty, we recommend confirming fitment by VIN.

Applications

• Honda HR-V 2016–2020 – 1.5 petrol naturally aspirated engine L15B4
• Honda Jazz 2018–2020 – 1.5 petrol naturally aspirated engine L15B3

Engine type: 1.5 petrol NA (non-turbo).

OEM reference numbers

The numbers below are provided as reference numbers only for fitment verification:

• 17131-5R1-000 (alt. format: 171315R1000)

When to replace / symptoms of wear

• hissing noise in the engine bay indicating a possible vacuum leak,
• unstable idle / rough running,
• lean mixture symptoms or fuel trim/adaptation issues,
• hose becomes hard/brittle, visible cracks or abrasion,
• oil mist or oily residue around the hose and its connections.

Installation & service tips

• Replace on a cool engine – plastic fittings and the hose are less likely to get damaged.
• Inspect clamps and mating nipples; worn clamps can cause small leaks.
• Make sure the hose is not kinked and follows the OEM routing (avoid rubbing against sharp edges).
• Do not use silicone/sealants on the joints – the PCV system must be sealed, but connections should remain serviceable like OEM.
• It’s a good idea to check the PCV valve and other breather hoses at the same time.
• After installation, verify: stable idle, no hissing, and no crankcase vapor smell in the engine bay.

FAQ – most common questions about Honda OEM PCV Hose 17131-5R1-000

1) Does this hose fit the 1.5 Turbo engines?
No. This part is intended for 1.5 naturally aspirated applications (L15B3/L15B4). Turbo versions use a different PCV/breather layout.

2) Can a leaking PCV hose cause rough idle?
Yes. A leak in the PCV circuit can act as unmetered air (“vacuum leak”), which may lead to unstable idle and incorrect fuel trims.

3) Do I need to replace the PCV valve as well?
Not always, but it’s worth inspecting it. A stuck or malfunctioning PCV valve can cause similar symptoms even with a new hose.

4) What is the best way to confirm fitment?
The most reliable method is a VIN check, as routing and small changes may vary by model year and market.
