Honda VTC Cam Gear 14310-5BY-H01 – HR-V / Jazz – L15B

Honda VTC cam gear 14310-5BY-H01 – variable timing actuator for L15B3 / L15B4 / L15BY

14310-5BY-H01 is a genuine Honda VTC cam gear (variable timing actuator) used in selected L15B-series naturally aspirated engines. It controls intake camshaft timing, improving performance, fuel efficiency and emissions in modern Honda engines.

This is the updated OEM part number which can be used directly in place of the earlier references:

• 14310-5R1-013
• 14310-5R1-003

All three part numbers refer to the same 46T VTC actuator. 14310-5BY-H01 is the latest supersession and is fully interchangeable with 14310-5R1-013 and 14310-5R1-003 in the listed engines.

Applications – compatible Honda engines and models

The VTC cam gear 14310-5BY-H01 fits the following naturally aspirated L15B engines and models:

• Honda HR-V 2016–2018 – engine L15B4
• Honda HR-V 2016–2020 – engine L15BY
• Honda Jazz 2018–2020 – engine L15B3

Important: this part does not fit turbocharged engines L15B7 (1.5 VTEC Turbo) used in Civic X / CR-V.

VTC function – what this cam gear does

The VTC (Variable Timing Control) system adjusts intake camshaft timing depending on load and RPM. The 14310-5BY-H01 actuator:

• optimises valve timing for better low-end torque and high-rpm power,
• helps reduce fuel consumption at part load,
• improves emissions and combustion stability,
• supports smooth cold starts and stable idle.

A worn or faulty VTC gear may cause rattling noise on cold start, poor performance, fault codes related to cam timing and rough engine operation. Replacing it with a new genuine unit restores correct phasing and smooth running.

Why choose the genuine Honda 14310-5BY-H01 VTC gear?

• Latest OEM part number superseding 14310-5R1-013 and 14310-5R1-003.
• Full compatibility with L15B3, L15B4 and L15BY engines.
• Exact fit and correct cam timing control.
• High durability and resistance to wear.
• Eliminates typical VTC rattle when the original gear is worn.

FAQ – VTC cam gear 14310-5BY-H01

Is 14310-5BY-H01 different from 14310-5R1-013?

Functionally no. 14310-5BY-H01 is the newer superseded OEM number for the same VTC cam gear. It directly replaces 14310-5R1-013 and 14310-5R1-003 in compatible engines.

Does this VTC gear fit all L15B engines?

No. It is designed for naturally aspirated L15B engines: L15B3, L15B4 and L15BY. It does not fit turbocharged L15B7 (1.5 VTEC Turbo) engines used in Civic X and CR-V.

What are common symptoms of a worn VTC gear?

Rattling noise at cold start, cam timing fault codes, unstable idle and noticeable loss of performance.

Should I replace seals when changing the VTC gear?

It is recommended to inspect and replace the camshaft oil seal if there are any signs of leakage, especially on high-mileage engines.
