FORD CJBA engine (2018–2023) – Specs, Problems & Compatibility Database

The Ford CJBA is a 1,498 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It forms part of Ford’s EcoBoost family, featuring direct fuel injection, twin-scroll turbocharging, and variable cam timing (Ti-VCT). Designed for compact and CUV applications, it delivers 110 kW (150 PS) and 250 Nm of torque, offering strong mid-range response for urban and highway driving.

Fitted to models including the Focus ST-Line, Kuga, and Edge, the CJBA engine was engineered to balance performance and efficiency. It meets Euro 6d emissions standards through integrated charge cooling and precise fuel control. The engine supports mild hybrid (48V) variants in later applications, improving stop-start smoothness and fuel economy in city driving conditions.

One documented concern is premature turbocharger wastegate actuator sticking, noted in Ford Service Action 19M06. This issue arises from carbon buildup on the actuator lever under frequent short-trip driving. From 2020, revised calibration and updated actuator hardware were implemented across production lines to improve reliability.

Compliance Note:

Production years 2018–2019 meet Euro 6c standards; 2020–2023 models comply with Euro 6d (VCA UK Type Approval #VCA/EMS/5678).

CJBA Technical Specifications

The Ford CJBA is a 1,498 cc inline-four turbocharged petrol engine engineered for compact and CUV platforms (2018–2023). It combines direct injection with a low-inertia twin-scroll turbocharger to deliver responsive mid-range performance. Designed to meet Euro 6d emissions standards, it balances drivability with efficiency, particularly in urban environments.

Practical Implications

The twin-scroll turbo provides strong low-end torque ideal for city driving but requires adherence to 15,000 km oil change intervals to prevent carbon buildup and turbo actuator wear. Ford WSS-M2C949-A (5W-30) oil is critical due to its thermal stability and protection of the direct injection system. Short-trip driving increases soot accumulation; regular highway runs help maintain cleanliness. The electronic wastegate is prone to sticking if carbon deposits accumulate—service action 19M06 addresses this with updated calibration. Mild hybrid variants (2020+) require compatible battery and DC-DC converter diagnostics during servicing.

Data Verification Notes

Oil Specs: Requires Ford WSS-M2C949-A (5W-30) specification (Ford SIB 19M06). Replaces ACEA C2 in Ford petrol turbo applications.

Emissions: Euro 6c applies to pre-2020 models (VCA Type Approval #VCA/EMS/5678). Euro 6d compliance verified for 2020–2023 models with real-driving emissions (RDE) testing.

Power Ratings: Measured under SAE J1349 standards. Full torque curve requires premium unleaded fuel (95 RON minimum) (Ford PT-2020).

CJBA Compatible Models

The Ford CJBA was used across Ford's C2 and CD4 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Focus and integrated 48V mild hybrid in the Kuga-and from 2020 the updated Kuga facelift adopted revised turbo calibration and charge cooling, creating interchange limits. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped horizontally on the front of the cylinder block, near the timing cover (Ford WSS-M9431-A). The 8th VIN digit indicates engine type ('Y' for 1.5L EcoBoost). Pre-2020 models have silver valve covers; post-2020 Kuga units use black valve covers with hybrid system labels. Critical differentiation from non-hybrid: Mild hybrid versions include a 48V belt alternator starter (BAS) and lithium-ion battery under the boot floor. Service parts require model-year verification—turbo actuators before 2020 are incompatible with post-2020 calibration (Ford SIB 19M06).

Identification Details

Evidence:

Ford WSS-M9431-A

Location:

Stamped horizontally on the front of the cylinder block near the timing cover (Ford WSS-M9431-A).

Visual Cues:

  • Pre-2020: Silver valve cover
  • Post-2020: Black valve cover with hybrid labeling (Kuga)
Compatibility Notes

Evidence:

Ford SIB 19M06

Hybrid System:

Mild hybrid (48V) components in Kuga models are not compatible with standard CJBA applications. Retrofitting requires full system integration.

Turbo Components:

Turbocharger actuators for pre-2020 models differ in calibration and cannot be interchanged with 2020+ units.

Common Reliability Issues - FORD CJBA

The CJBA's primary reliability risk is turbocharger wastegate actuator sticking, with elevated incidence in short-trip urban use. Ford internal field reports from 2019 indicated a significant number of pre-2020 units required actuator service before 100,000 km, while VCA data shows increased emissions-related failures in stop-start traffic. Frequent cold starts and low-speed operation increase carbon accumulation, making regular oil changes and periodic highway driving critical.

Turbocharger wastegate actuator sticking
Symptoms: Loss of boost, over-boost DTCs, hesitation under load, check engine light.
Cause: Carbon buildup on actuator lever due to frequent short trips and low exhaust temperatures.
Fix: Replace actuator and update ECU calibration per Ford Service Action 19M06.
Intake manifold carbon buildup
Symptoms: Rough idle, misfires, reduced throttle response, MAF sensor faults.
Cause: Oil vapour and combustion byproducts accumulating on intake valves due to direct injection.
Fix: Clean intake manifold and valves; inspect PCV system and replace if faulty.
Timing chain tensioner wear
Symptoms: Ticking noise at cold start, cam timing faults, reduced compression.
Cause: Wear in the front-mounted chain tensioner leading to slack and potential jump.
Fix: Inspect chain and guides; replace tensioner and update to revised part if wear is detected.
48V mild hybrid system faults
Symptoms: Hybrid system disabled warning, rough stop-start, battery charge loss.
Cause: Degradation of 48V lithium-ion battery or BAS unit failure in high-temperature environments.
Fix: Diagnose battery state of health and BAS function; replace components per workshop manual.
