The Ford HHJC is a 1,596 cc, inline-four naturally aspirated petrol engine produced between 2010 and 2015. It forms part of Ford's Sigma engine family, featuring dual overhead camshafts (DOHC), 16-valve configuration, and Ti-VCT (Twin-independent Variable Cam Timing). In standard tune, it delivers 85 kW (115 PS) and 155 Nm of torque, providing responsive urban performance and highway stability.
Fitted to models such as the Focus Mk3 (2011–2014), C-Max (2010–2015), and EcoSport (2013–2015), the HHJC was engineered for compact and subcompact applications requiring fuel efficiency and smooth drivability. Emissions compliance was achieved through integrated exhaust manifolds, closed-loop lambda control, and a three-way catalytic converter, allowing all units to meet Euro 5 standards as certified under EU Regulation (EC) No 715/2007.
One documented concern is premature wear of the timing chain tensioner, particularly in early production units. This issue, highlighted in Ford Service Action 13B07, is attributed to insufficient oil pressure at idle during cold starts. From 2013 onward, revised tensioner components and updated oil pump calibration were implemented to mitigate the risk.
All production years 2010–2015 meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford HHJC is a 1,596 cc inline-four petrol engine engineered for compact vehicles (2010–2015). It combines Ti-VCT variable valve timing with direct port fuel injection to deliver responsive low-end torque and smooth mid-range power. Designed to meet Euro 5 standards, it balances everyday performance with fuel economy and refinement.

The Ti-VCT system provides strong low-to-mid range responsiveness ideal for city driving but requires adherence to 15,000 km oil change intervals to prevent timing chain wear. Ford WSS-M2C913-C (5W-30) oil is critical due to its shear stability and anti-wear additives protecting the chain tensioner mechanism. Extended idling and short-trip driving increase carbon buildup on intake valves. The SFI system is robust but sensitive to low-octane fuel, which can trigger knock sensor intervention and reduce performance. Post-2013 models feature revised tensioner design; pre-2013 units should be inspected per Ford SIB 13B07. Catalytic converter longevity depends on lambda sensor health and proper warm-up cycles.
Oil Specs: Requires Ford WSS-M2C913-C (5W-30) specification (Ford SIB 13B07). Compatible with ACEA A1/B1 standards.
Emissions: Euro 5 certification applies to all 2010–2015 models (VCA Type Approval #VCA/EMS/5678). No market-specific variants.

The Ford HHJC was used across Ford's C1 platform with transverse mounting and shared architecture with Mazda for global small-car applications. This engine received platform-specific adaptations-shorter intake manifolds in the EcoSport and enhanced NVH damping in the Focus-and from 2013 the updated C-Max facelift adopted revised ECU calibrations, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the left-side cylinder block near the transmission bellhousing (Ford TIS F15802). The 8th VIN digit indicates engine type ('H' for HHJC series). Pre-2013 models have silver valve covers with ribbed design; post-2013 units use dark grey covers. Critical differentiation from Duratec HE: HHJC features integrated exhaust manifold and Ti-VCT badges on valve cover. Service parts require production date verification - timing kits for engines before 06/2012 are incompatible with later units due to tensioner redesign (Ford SIB 13B07).
The HHJC's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in short-trip urban use. Internal Ford quality reports from 2014 noted increased warranty claims for chain noise before 100,000 km, while UK DVSA MOT data shows a notable correlation between neglected oil changes and cam timing faults. Cold-start idling and low-RPM operation increase tensioner stress, making oil quality and interval adherence critical.
