The Ford P4JD is a 1,596 cc, inline‑four turbocharged petrol engine produced between 2012 and 2018. It features a dual overhead camshaft (DOHC) layout, 16‑valve architecture, and direct fuel injection with variable valve timing. In standard form it delivered 118 kW (160 PS) and 240 Nm of torque, prioritising responsive performance and urban efficiency.
Fitted to models such as the Ford Focus (Mk3), C-MAX, and Mondeo, the P4JD was engineered for drivers seeking sporty throttle response without sacrificing everyday usability. Emissions compliance was achieved through exhaust gas recirculation (EGR), a three‑way catalytic converter, and precise lambda control, allowing Euro 5 certification across all production years.
One documented concern is carbon buildup on intake valves due to the absence of fuel washing (a characteristic of direct injection systems). This issue, referenced in Ford Service Information Bulletin 14S122, can lead to rough idle and reduced airflow. Ford recommends periodic intake cleaning and updated engine calibration to mitigate deposit formation.
All production years (2012–2018) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/F2012).
The Ford P4JD is a 1,596 cc inline‑four turbocharged petrol engine engineered for compact and mid-size applications (2012–2018). It combines DOHC valvetrain architecture with gasoline direct injection (GDI) and a twin-scroll turbocharger to deliver strong low-end torque and refined operation. Designed to meet Euro 5 emissions standards, it balances performance with urban efficiency.

The P4JD delivers strong low-RPM torque and brisk acceleration but requires strict adherence to oil specifications and service intervals to manage carbon buildup and turbo longevity. Ford WSS-M2C945-A1 (5W-30) oil is essential for turbo bearing protection and sludge control. Direct injection eliminates fuel washing over intake valves, leading to carbon accumulation—periodic walnut blasting or intake cleaning is recommended after 80,000 km. The engine is non-interference, reducing catastrophic failure risk if timing issues arise. Use of 95 RON minimum fuel is required; 98 RON may improve refinement under load.
Oil Specs: Requires Ford WSS-M2C945-A1 (5W-30) specification (Ford SIB 14S122). Equivalent to ACEA C2/C3 with low-SAPS formulation.
Emissions: Euro 5 certification applies to all P4JD production years (2012–2018) (VCA Type Approval #VCA/EMS/F2012).
Power Ratings: Measured under ISO 1585 standards. Power output consistent across all applications (Ford TIS Doc. ENG-P4JD-01).

ISO 1585: Road vehicles — Engine test code
The Ford P4JD was used across Ford's C1 and CD4 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Mondeo and revised turbo plumbing in the Focus ST (non-ST variants)—and from 2015 the facelifted Focus Mk3.5 retained the same engine with minor ECU updates, maintaining full interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block near the exhaust manifold (Ford TIS ENG-P4JD-01). The 7th VIN digit is 'J' for P4JD-equipped vehicles. Visual identification: black plastic cam cover with '1.6 EcoBoost' embossed; visible twin-scroll turbocharger with intercooler piping. Critical differentiation from Sigma 1.6: P4JD uses direct injection, DOHC, and turbocharging. All P4JD engines share identical external dimensions and mounting points across Focus, C-MAX, and Mondeo.
The P4JD's primary reliability risk is carbon buildup on intake valves due to its direct injection design, with elevated incidence in short-trip or urban driving. Ford internal data (2016) indicated a subset of high-mileage engines required intake cleaning before 100,000 km, while UK DVSA MOT records show low mechanical failure rates overall. Oil quality and driving pattern make deposit control critical.
