The Peugeot T9A (DJ5) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 1997 and 2001. It features multi-point fuel injection, a single overhead camshaft (SOHC), and two valves per cylinder. In standard applications, it produces 66 kW (90 PS) and 130 Nm of torque, offering dependable performance for compact city and suburban driving.
Fitted primarily to the 206 hatchback, the T9A was engineered for cost-effective ownership, fuel efficiency, and ease of maintenance. Emissions compliance was achieved through a closed-loop fuel system and catalytic converter, meeting Euro 2 standards for its entire production run.
A documented concern involves premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure. This issue, referenced in Peugeot Service Bulletin 5892B, is often linked to bearing fatigue. Later production units incorporated a revised tensioner design for improved service life.
Production years 1997–2001 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5676).
The Peugeot T9A (DJ5) is a 1,587 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (1997-2001). It combines multi-point fuel injection with a robust SOHC valvetrain to deliver predictable, economical performance. Designed to meet Euro 2 standards, it prioritizes simplicity and low running costs for urban mobility.

The SOHC design offers mechanical simplicity but requires strict adherence to 60,000 km timing belt and tensioner replacement intervals to prevent catastrophic failure. The Bosch Motronic system is robust but sensitive to poor-quality fuel; using 95 RON minimum is recommended. The catalytic converter is durable but can be damaged by unburnt fuel from misfires; address ignition faults immediately. Replace the tensioner with the revised unit per SIB 5892B during any belt service.
Oil Specs: Requires PSA B71 2290 (10W-40) specification for optimal protection (Peugeot Owner's Manual).
Emissions: Euro 2 certification applies to all production years (1997-2001) (VCA Type Approval #VCA/EMS/5676).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Peugeot Technical Note TN-07/1997).

VCA Type Approval Database (VCA/EMS/5676)
The Peugeot T9A (DJ5) was used exclusively in Peugeot's PF1 platform with transverse mounting. This engine received no major platform-specific adaptations, ensuring broad parts interchangeability across its model range. All service procedures are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot Workshop Manual 0515.T9). The engine code 'T9A' is also listed on the vehicle's build sticker, typically found in the driver's door jamb. Visually, it can be identified by its silver rocker cover with '16V' branding (despite being 8-valve) and the absence of a turbocharger. Differentiate from the higher-powered TU5JP4 (110 PS) by checking the power output in the ECU or the vehicle registration document. Timing belt tensioner revisions (pre/post SIB 5892B) require checking the pulley part number for correct replacement.
The T9A's primary reliability risk is timing belt tensioner pulley failure, with elevated incidence in vehicles exceeding the 60,000 km service interval. Peugeot internal reports linked a significant number of failures to bearing fatigue, while workshop data shows ignition coil faults are common in high-mileage examples. Adherence to the timing belt service schedule is critical to prevent costly engine damage.
