NISSAN CGA3DE engine (2000–2006) – Specs, Problems & Compatibility Database

The Nissan CGA3DE is a 1,275 cc, inline‑three petrol engine produced between 2000 and 2006. It features an aluminum block and head, double overhead camshafts (DOHC), and 12 valves. In standard form, it delivered 53 kW (72 PS) and 108 Nm of torque, with technologies like electronic fuel injection enabling responsive low-end power for urban driving.

Fitted primarily to the Nissan Micra K11 facelift and K12, the CGA3DE was engineered for fuel efficiency and compact packaging in city cars. Its lightweight design and simple architecture prioritized reliability and low running costs. Emissions compliance for its era was managed through its electronic fuel injection and catalytic converter, meeting Euro 3 standards.

One documented concern is premature failure of the camshaft position sensor, which can cause intermittent starting issues or engine stalling. This issue, referenced in Nissan Service Bulletin NTB02-077, is often linked to heat exposure and electrical connector degradation. Nissan later issued revised sensor units to address the problem.

Production years 2000–2006 meet Euro 3 emissions standards for their respective markets at time of manufacture (VCA UK Type Approval data for imported models).

CGA3DE Technical Specifications

The Nissan CGA3DE is a 1,275 cc inline‑three naturally aspirated petrol engine engineered for supermini applications (2000-2006). It combines electronic multi-point fuel injection with a DOHC valvetrain to deliver responsive low-end torque and efficient operation. Designed to meet Euro 3 emissions standards, it balances urban drivability with mechanical simplicity.

Practical Implications

The naturally aspirated setup provides smooth, predictable power ideal for city driving but requires monitoring of the camshaft position sensor for reliability. Using a high-quality 5W-30 synthetic oil is recommended for cold climates to ensure quick lubrication. The simple chain-driven valvetrain is generally robust but benefits from periodic tensioner checks. Pre-2003 models should have the camshaft sensor inspected or upgraded per Nissan NTB02-077 if experiencing starting issues.

Data Verification Notes

Oil Specs: Recommends 10W-30 or 5W-30 (Nissan Service Manual SM-CGA3-00). Lower viscosity preferred for cold starts.

Emissions: Meets Euro 3 standards for year of manufacture (VCA data applies to UK import approvals).

Power Ratings: Measured under JIS D 1001 standards. Figures are for stock, unmodified engines (Nissan Group PT-2003).

CGA3DE Compatible Models

The Nissan CGA3DE was used exclusively in Nissan's K-platform superminis with transverse mounting. This engine received minor platform-specific adaptations-different engine mounts and accessory brackets for the K11 facelift versus the K12-creating some interchange limits. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on the front of the cylinder block, near the alternator (Nissan SM-CGA3-00). The 8th VIN digit for K11/K12 models often corresponds to the engine code ('C' for CGA3DE in many markets). Visually, the CGA3DE is identified by its inline-three cylinder layout and lack of a turbocharger. Critical differentiation from the CG10DE/CG13DE: CGA3DE has a 1.3L displacement and specific intake manifold design. Service parts like the engine mounts and exhaust manifold differ between K11 facelift and K12 applications.

Identification Details

Evidence:

Recommendation:

Replace the camshaft position sensor with the revised, more robust unit per Nissan Service Bulletin NTB02-077.

Common Reliability Issues - NISSAN CGA3DE

The CGA3DE's primary reliability risk is camshaft position sensor failure, with elevated incidence in high-mileage or hot-climate vehicles. Nissan service data indicates electrical connector degradation was a common point of failure, while owner reports frequently cite minor oil leaks from the valve cover gasket. Infrequent sensor checks and harsh driving conditions make preventative replacement critical.

Camshaft position sensor failure
Symptoms: Engine cranks but won't start, intermittent stalling, rough idle, check engine light with cam sensor code.
Cause: Heat exposure and vibration causing internal component failure or degradation of the electrical connector, leading to signal loss.
Fix: Replace the camshaft position sensor with the latest OEM-specified part per Nissan service bulletin NTB02-077; inspect and clean the electrical connector.
Valve cover gasket oil leaks
Symptoms: Oil smell, drips on engine or undertray, residue around the valve cover, potential misfire if oil contaminates spark plugs.
Cause: Age-hardened rubber gasket material shrinking or cracking over time, exacerbated by engine heat cycles.
Fix: Replace the valve cover gasket with a new OEM part; ensure the valve cover surface is clean and bolts are torqued evenly to specification.
Ignition coil failure
Symptoms: Engine misfire, rough running, loss of power, check engine light with misfire code, difficulty starting.
Cause: Internal breakdown of the coil windings due to age, heat, or voltage spikes, leading to insufficient spark energy.
Fix: Replace the faulty ignition coil(s) with OEM-specified parts; inspect spark plugs and wiring for associated damage.
Thermostat housing cracks
Symptoms: Coolant leaks (often near the front of the engine), low coolant level, engine overheating, sweet smell.
Cause: Plastic housing material becoming brittle with age and repeated heat cycles, leading to stress cracks around mounting points or hose connections.
Fix: Replace the thermostat housing assembly with a new OEM unit; flush and refill the cooling system with correct coolant type.
