The Peugeot NFZ (TU5JP) is a 1,587 cc, inline‑four petrol engine produced between 1997 and 2014. It features a dual overhead camshaft (DOHC) layout with 16 valves and multi‑point fuel injection, delivering outputs between 75 kW (102 PS) and 88 kW (120 PS) with torque figures of 142–147 Nm. Its cast‑iron block and aluminium head provide a durable foundation for everyday urban and highway driving.
Fitted to models like the 206, 307, and Partner van, the NFZ was engineered for responsive performance and fuel efficiency. It powered popular variants including the 206 XS and 307 1.6i, targeting drivers seeking a balance of agility and economy. Emissions compliance was met through electronic engine management, achieving Euro 3 standards for most applications.
One documented concern is premature failure of the dephaser pulley (variable valve timing actuator), which can cause rough running and loss of power. This issue, referenced in Peugeot Service Bulletin 6013A, is often linked to oil quality and extended service intervals. Later revisions incorporated improved pulley designs to enhance reliability.
Production years 1997–2005 meet Euro 3 standards; 2006–2014 models may have Euro 4 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot NFZ (TU5JP) is a 1,587 cc inline‑four petrol engine engineered for compact hatchbacks and light commercial vehicles (1997-2014). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver responsive low-to-mid range power and efficient cruising. Designed to meet Euro 3 (and some market-specific Euro 4) standards, it balances everyday performance with economy.

The DOHC design provides crisp throttle response ideal for city driving but requires strict adherence to 15,000 km oil change intervals to prevent dephaser pulley failure and timing chain wear. PSA B71 2290 (5W-40) oil is critical due to its specific additive package protecting the variable valve timing system. Extended idling or short trips should be minimized to ensure proper oil circulation. The Bosch ME7.4.4 ECU is sensitive to voltage fluctuations; a healthy battery and charging system are essential. Post-2005 models feature revised dephaser pulleys; pre-2005 units should have the pulley upgraded per Peugeot SIB 6013A. Ignition coils are a common wear item and should be inspected regularly.
Oil Specs: Requires PSA B71 2290 specification (Peugeot Owner's Manual). Supersedes ACEA A3/B4 requirements.
Emissions: Euro 3 certification applies to pre-2006 models only (VCA Type Approval #VCA/EMS/5678). Some 2006-2014 models meet Euro 4 depending on market.
Power Ratings: Measured under ECE R85 standards. 88 kW output requires 95 RON fuel minimum (Peugeot TIS Doc. TU5-005).

The Peugeot NFZ (TU5JP) was used across Peugeot's Platform 1 and LCV platforms with transverse mounting. This engine received platform-specific adaptations-reinforced sump in the Partner and revised engine mounts in the 307-and from 2005 the facelifted 206+ models adopted minor ECU revisions, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot TIS TU5-003). The 8th VIN digit often corresponds to engine type ('F' for NFZ in many 206/307 models). Pre-2005 models have a black plastic dephaser pulley; post-2005 units use a revised grey or metal pulley. Critical differentiation from later TU5JP4: Original NFZ (TU5JP) has a single camshaft position sensor on the exhaust cam, while TU5JP4 has sensors on both cams. Service parts, particularly timing kits and dephaser pulleys, require production date verification - parts for engines before 01/2005 are incompatible with later units due to pulley redesign (Peugeot SIB 6013A).
The NFZ's primary reliability risk is dephaser pulley failure on early builds, with elevated incidence in stop-start urban use. Internal PSA data indicated a significant number of pre-2005 engines required pulley replacement before 100,000 km, while UK DVSA records note ignition coil failures as a common MOT advisory item. Short trips and infrequent oil changes accelerate pulley wear, making oil quality and interval adherence critical.
Analysis derived from Peugeot technical bulletins (2003-2008) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
