P2026 Mercury Code - Evaporative Emissions Fuel Vapor Temperature Sensor Circuit Low Voltage

Quick Answer

The Powertrain Control Module (PCM) monitors the Natural Vacuum Leak Detection (NVLD) module input for expected NVLD ambient temperature sensor values. Common causes include Faulty Natural Vacuum Leak Detection (NVLD) module, Natural Vacuum Leak Detection (NVLD) module harness is open or shorted, Natural Vacuum Leak Detection (NVLD) module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
