Nissan Sylphy G10 ECU Repair – Misfire on Ignition Coil (2000–2005)

Engine ECU Ignition Driver Fault | Cylinder Misfire Repair

This is a repair service for the ECU (Engine Control Unit) in the 2000–2005 Nissan Sylphy G10, specifically targeting a misfire fault caused by a failure in the ignition coil driver circuit. These ECUs are prone to internal faults that cause one or more ignition coils to lose power or signal, resulting in persistent misfires.

Common Symptoms Repaired:

• Engine misfiring on one or more cylinders

• Coil has power and ground but no firing signal

• DTCs for cylinder misfire (e.g. P030X) that remain after replacing coils/plugs

• Poor performance, rough idle, or hesitation under load

• No improvement with known-good ignition components

What We Do:

• Diagnose and repair failed coil driver circuitry

• Replace degraded internal components with robust parts

• Inspect board for heat damage, cracks, or track failures

• Bench test ECU outputs for all ignition channels

Applies To:

• Nissan Sylphy G10 (2000–2005)

• Petrol engines with conventional coil-on-plug ignition

• ECU models specific to the G10 platform (please confirm part number if unsure)

Turnaround Time: 2–3 business days
