MAZDA LFVE engine (2014–2018) – Specs, Problems & Compatibility Database

The Mazda LFVE is a 2,488 cc, inline‑four petrol engine produced between 2014 and 2018. It features an aluminium block and head, DOHC, and direct fuel injection with variable valve timing. This engine, part of the Skyactiv-G family, delivers a balance of performance and efficiency for its class, producing 138 kW (187 PS) and 250 Nm of torque in its most common configuration.

Fitted to models like the Mazda6 (GJ) and CX-5 (KE), the LFVE was engineered for responsive highway driving with an emphasis on smooth power delivery and mid-range torque. Emissions compliance for its era was managed through its direct injection system and advanced exhaust after-treatment, meeting Euro 6 standards for European markets and equivalent regulations elsewhere.

One documented service consideration involves potential for high-pressure fuel pump failure, which can trigger check engine lights and affect drivability. Mazda service documentation, such as Technical Service Bulletin 01-004/16, notes this as a known issue on higher-mileage units, often linked to fuel quality or lubrication factors.

Practical Implications

The high 13:1 compression ratio provides excellent thermal efficiency for strong fuel economy but requires strict adherence to using 0W-20 oil to ensure proper lubrication and cooling. The direct injection system demands high-quality fuel to prevent carbon buildup on intake valves. The timing chain is generally robust but should be inspected for wear or noise during major services. The high-pressure fuel pump is a known wear item and should be monitored for symptoms of failure.

Data Verification Notes

Oil Specs: Requires SAE 0W-20 with API SN rating or equivalent specification (Mazda Workshop Manual, Mazda6).

Emissions: Euro 6 certification applies to all 2014-2018 models for applicable markets (VCA Type Approval #VCA/MZ/10234).

Power Ratings: Measured under SAE J1349 standards. Output figures are for naturally aspirated variants (Mazda PT-2017).

LFVE Compatible Models

The Mazda LFVE was used across Mazda's Mazda6 and CX-5 platforms with transverse mounting. This engine received minor ECU and accessory drive adaptations for different model years and markets, creating potential interchange limits for ancillary components. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on the front face of the cylinder block, near the timing cover (Mazda Workshop Manual, Mazda6). The 8th digit of the VIN typically corresponds to the engine type for this era. The LFVE is visually identified by its inline-four configuration, aluminium block, and "LF" casting marks on the block. Critical differentiation from the smaller Skyactiv-G 2.0L (PE-VPS): The LFVE has a larger displacement (2.5L vs 2.0L) and different bore/stroke dimensions. When sourcing parts, verify the specific model year and market, as accessory brackets and ECU calibrations can vary.

High-Pressure Fuel Pump

Issue:

The high-pressure fuel pump can fail due to wear or lubrication issues, leading to drivability problems and check engine lights.

Evidence:

Mazda Technical Service Bulletin 01-004/16

Recommendation:

Use high-quality Top Tier fuel and adhere to recommended oil change intervals. Replace the pump with a new OEM-specified part if faulty per TSB 01-004/16.
Timing Chain

Note:

While generally reliable, the timing chain and tensioner should be inspected for wear or noise during major engine services (150,000+ km).

Evidence:

Mazda Service Bulletin, Engine-15-01

Common Reliability Issues - MAZDA LFVE

The LFVE's primary reliability risk is age-related failure of the high-pressure fuel pump, with elevated incidence in high-mileage or poorly maintained examples. Mazda service documentation highlights pump failure as a common cause for drivability complaints. Extended service intervals and use of incorrect oil or low-quality fuel can accelerate wear on internal engine components, making adherence to the factory maintenance schedule critical.

High-pressure fuel pump failure
Symptoms: Check engine light (often P0087, P0627 codes), loss of power, engine stalling, difficulty starting.
Cause: Internal wear or lubrication failure within the high-pressure fuel pump, preventing it from generating sufficient fuel pressure for the direct injection system.
Fix: Replace the faulty high-pressure fuel pump with a new OEM-specified part per Mazda TSB 01-004/16; ensure fuel and oil quality meet specifications.
Intake valve carbon buildup
Symptoms: Rough idle, cold start misfires, decreased power, increased fuel consumption.
Cause: Accumulation of carbon deposits on the back of the intake valves, a common trait of direct injection engines without port injection to clean the valves.
Fix: Perform an intake valve cleaning procedure (walnut blasting or chemical cleaning) per OEM guidelines; consider using Top Tier fuel to reduce future buildup.
Variable valve timing (VVT) solenoid failure
Symptoms: Check engine light (often P0011, P0021 codes), rough idle, decreased power, poor fuel economy.
Cause: Internal wear or clogging of the VVT solenoid due to oil sludge or debris, preventing proper oil pressure control to the cam phasers.
Fix: Replace the faulty VVT solenoid with a new OEM-specified part; ensure engine oil is clean and at the correct level and viscosity.
Valve cover gasket leaks
Symptoms: Oil residue on the top of the engine, burning oil smell, low oil level.
Cause: Age-hardening and shrinkage of the rubber valve cover gasket, leading to loss of seal.
Fix: Replace valve cover gasket with a new OEM part; ensure valve cover bolts are torqued to specification in the correct sequence.
