P2027 Lincoln Code - Evaporative Emissions Fuel Vapor Temperature Sensor Circuit High 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.

Frequently Asked Questions about P2027 Lincoln Code
What does the OBDII code P2027 mean on a Lincoln?
P2027 indicates a high voltage issue in the Evaporative Emissions Fuel Vapor Temperature Sensor Circuit, which monitors fuel vapor temperature as part of the emissions control system.
What are common symptoms of the P2027 code on a Lincoln?
Symptoms may include an illuminated check engine light, poor fuel economy, failed emissions test, or inconsistent engine performance.
What causes the P2027 code to appear?
Common causes include a faulty fuel vapor temperature sensor, damaged wiring or connectors in the circuit, or a malfunctioning powertrain control module (PCM).
Can I drive my Lincoln with the P2027 code active?
While the vehicle may still be drivable, ignoring this code can lead to increased emissions and potential damage to other components over time.
How do I diagnose the P2027 code on my Lincoln?
Start by inspecting the wiring and connectors for damage or corrosion, testing the fuel vapor temperature sensor for proper function, and checking for related codes.
How do I fix the P2027 code on a Lincoln?
Repairs may include replacing the fuel vapor temperature sensor, repairing damaged wiring or connectors, or updating/reprogramming the PCM if necessary.
How much does it cost to repair the P2027 code on a Lincoln?
Repair costs vary, but replacing the fuel vapor temperature sensor typically ranges between $150 and $300, including parts and labor.
Can a bad PCM cause the P2027 code?
Yes, although rare, a faulty PCM can cause the P2027 code if it fails to properly read or process signals from the sensor.
Will clearing the code solve the issue?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be resolved to prevent the code from returning.
Is the P2027 code specific to Lincolns?
No, the P2027 code is a generic OBDII code applicable to many vehicles, though its exact symptoms and repair procedures may vary by make and model.
