HONDA N16A1 engine (2011–2015) – Specs, Problems & Compatibility Database

The Honda N16A1 is a 1,597 cc, inline‑four naturally aspirated petrol engine produced between 2011 and 2015. It features i-VTEC variable valve timing and lift, dual overhead camshafts (DOHC), and a chain-driven timing system. This engine was designed for efficiency and smooth operation, producing 93 kW (125 PS) and 155 Nm of torque, making it suitable for compact SUV applications.

Fitted primarily to the second-generation Honda CR-V (facelift) and the European-market Honda Civic Tourer, the N16A1 was engineered to provide reliable, economical performance for daily commuting and light touring. Emissions compliance was achieved through precise fuel injection and catalytic converter technology, meeting Euro 5 standards.

One documented engineering refinement addressed minor oil consumption in early production units, resolved by a piston ring update detailed in Honda Service Information Bulletin SIB-12-045. This update improved long-term oil control and was implemented in engines produced after March 2013.

Practical Implications

The naturally aspirated design offers predictable, linear power delivery ideal for relaxed driving but lacks low-end torque for heavy loads or steep hills. The 0W-20 or 5W-30 oil specification is critical for maintaining i-VTEC function and chain lubrication. Honda recommends oil changes every 15,000 km or 12 months under normal conditions. The timing chain is designed for the engine's lifetime, eliminating the need for costly belt replacements. Minor oil consumption in pre-2013 engines can be mitigated by using a higher viscosity 5W-30 oil and ensuring the PCV system is functioning correctly, as per SIB-12-045.

Data Verification Notes

Oil Specs: Requires Honda 0W-20 or 5W-30 specification for warranty compliance (Honda Owner's Manual).

Emissions: Euro 5 certification applies to all N16A1 engines (VCA Type Approval #VCA/EMS/HON-N16A1).

Power Ratings: Measured under SAE J1349 standards. Peak figures require 95 RON fuel (Honda TIS Doc. N16A1-PERF-01).

Identification Guidance

Locate the engine code stamped on the front of the engine block, near the exhaust manifold (Honda TIS N16A1-ID-01). The 8th VIN digit for CR-V models is 'R', while for the Civic Tourer it is 'S'. Visually, the engine has a silver plastic engine cover with "i-VTEC" branding. Critical differentiation from the turbocharged R18Z7: The N16A1 lacks a turbocharger and associated piping. Service parts, particularly for the cylinder head and valvetrain, are generally interchangeable across all N16A1 applications.

Identification Details

Evidence:

Honda TIS Doc. N16A1-ID-01

Location:

Stamped on the front face of the engine block, adjacent to the exhaust manifold (Honda TIS N16A1-ID-01).

Visual Cues:

  • Silver plastic engine cover with prominent 'i-VTEC' lettering.
  • No visible turbocharger or intercooler pipes.
Compatibility Notes

Evidence:

  • Honda SIB SIB-12-045
  • Honda TIS Doc. N16A1-ENG-01

E C U Software:

ECU software is identical across CR-V and Civic Tourer applications, allowing for interchangeability if hardware (sensors, injectors) matches.

Piston Rings:

Engines produced before March 2013 (VINs before XXXXXXXX) may benefit from the updated piston ring set (Part No. 13010-R40-A01) as per SIB-12-045 to address potential oil consumption.

Common Reliability Issues - HONDA N16A1

The N16A1's primary reliability focus is managing minor oil consumption in early production units, a phenomenon documented in Honda's internal quality reports from 2012. While NHTSA data shows a very low rate of mechanical failures for this engine, consistent use of the correct oil grade and adherence to service intervals are critical for long-term health, especially in vehicles used for frequent short trips.

Minor oil consumption (early production)
Symptoms: Gradual drop in oil level between changes (e.g., 0.5L per 5,000 km), no visible leaks, blue smoke on startup (rare).
Cause: Early-design piston rings (pre-March 2013) had slightly less effective oil control under certain operating conditions.
Fix: For affected engines, switch to 5W-30 oil and monitor consumption. If excessive, install the updated piston ring set (Part No. 13010-R40-A01) as per SIB-12-045.
VTEC solenoid failure
Symptoms: Check Engine Light (CEL) with code P2646/P2647, loss of high-RPM power, 'ticking' noise from the top of the engine.
Cause: Internal wear or electrical failure in the VTEC oil pressure switch or solenoid, preventing the system from engaging.
Fix: Replace the faulty VTEC solenoid or pressure switch with the latest OEM-specified part; clear ECU codes after repair.
Coolant thermostat failure (stuck closed)
Symptoms: Engine overheating warning, heater not working, temperature gauge reading very high or very low.
Cause: Mechanical failure of the wax-element thermostat, preventing it from opening and allowing coolant flow.
Fix: Replace the entire thermostat housing assembly with the latest OEM part to ensure a proper seal and function.
Engine mount wear
Symptoms: Increased vibration at idle, clunking noise when shifting gears or going over bumps, visible cracks in rubber mounts.
Cause: Ageing and hardening of the rubber in the hydraulic engine mounts, reducing their ability to dampen vibrations.
Fix: Replace worn engine mounts with OEM-specified parts to restore smooth operation and prevent stress on other components.
