Code P2027 Lincoln Description
The P2027 diagnostic trouble code (DTC) for Lincoln vehicles indicates a problem with the Evaporative Emissions Fuel Vapor Temperature Sensor Circuit, specifically showing high voltage. The evaporative emission system plays a crucial role in reducing harmful emissions released into the atmosphere by capturing and storing fuel vapors from the fuel tank. The fuel vapor temperature sensor is a key component of this system, responsible for monitoring the temperature of the fuel vapors to ensure proper operation.
Common Causes of P2027 Lincoln
- Faulty evaporative emissions fuel vapor temperature sensor
- Corroded or damaged wiring in the sensor circuit
- Issues with the evaporative emission control system
- Electrical faults in the sensor circuit
- Poor quality fuel or fuel contamination
Symptoms of P2027 Lincoln
- Check engine light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idle or stalling
- Unusual odors of fuel vapors
- Difficulty starting the vehicle
How to Fix P2027 Lincoln
- Diagnose the issue by using a scan tool to retrieve the DTC and inspect the evaporative emissions fuel vapor temperature sensor and circuit.
- Test the sensor's resistance and voltage to determine if it is functioning correctly.
- Inspect the wiring and connections for any damage, corrosion, or loose connections.
- Replace the evaporative emissions fuel vapor temperature sensor if it is found to be faulty.
- Clear the DTC and reset the check engine light to ensure the issue has been resolved.
Cost to Fix P2027 Lincoln
The typical repair costs for addressing a P2027 code on a Lincoln vehicle can range from $150 to $400, including parts and labor.

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.
