P2027 OBD Error Code: Problem & Solutions
OBD Code P2027 - Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Circuit High Voltage
The first thing to do when you have the check
engine light on is to find out what the reason is. Once you have found the code
that has been set you can proceed with resolving it. In this case you have the
P2027 code set by the Powertrain Control Module (PCM) of your vehicle, which
means that is has found that the Fuel Tank Temperature sensor is not working as
needed to monitor the temperature of the fuel in your vehicles tank. This code
is defined as a Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor
circuit high voltage. Read more to know how you can diagnose this code.

The vehicle’s Powertrain
Control Module (PCM) performs the job of monitoring the NVLD (Natural VAcuum
Leak Detection) module input, it this to be able to pick up the ambient
temperature sensor values expected by the NVLD. When these values aren’t in
sync with the limits of the vehicle the P2027 code will be set. In some
vehicles the Fuel Tank Temperature sensor is used to monitor the temperature of
the fuel that’s left in the tank, this is a very important task for engines
health.
What causes this problem
with the Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Circuit
High Voltage?
- Problems in the EVAP sensor
- Blockage or leak within system can be found
- The EVAP fuel vapor temperature sensor wiring harness are either
broken or damaged
- Short Wire
- Issue with the Pin/connector like corrosion, melting, burning,
bending etc
- Circuit is showing increased resistance
- Failure of the ECM (Engine Control Module)
Replace/Repair These Parts To Fix Code P2027
- Fuel Vapor Temperature Sensor - Has the
responsibility of monitoring fuel vapor
temperature present in the fuel tank or charcoal canister. All problems can be
resolved via repairs or replacement.
- Fuel Tank Temperature Sensor - Updates the ECU to
adjust the amount of fuel that is injected. Malfunction of the sensor can cause
wrong amount of fuel to be injected. Repair or replace it as needed. Find the

- Purge Control Valve Solenoid - It is part of the
EVAP system and controls the amount of fuel vapor purged from the
charcoal canister. When it’s not working properly it can damage the EVAP. Don’t
delay repairs and if needed go for replacement and let go fo the P2027 code.
- Charcoal Canister - Absorbs the fuel vapor that would pushed out into the atmosphere,
inturn causing pollution. You can repair or replace it s needed to resolve the
P2027 code.
- Electronic Sensor - Are important and help to pick up information about various
components of the vehicle and transfer this information to the PCM. Problems
with sensors can result in wrong information being delivered and hence can
interfere with the functioning of your car. Repair or replace them as needed.

Diagnosing Of Engine Error OBD Code P2027
It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2027 code to be stored:
Get hold of the standard OBD scanner and connect it to the vehicle diagnostic port and retrieve all the codes and freeze frame the data. Any codes if present prior to the P2027 will have to be sorted out first, as they could’ve been the reason this OBD code was set in the first place. Next it’s time to reset the trouble codes, and test-drive the vehicle to see if the code returns. If it does, then you will have to continue the diagnosis, if not then there may be an intermittent condition.
You can now begin the diagnosis starting with a thorough visual inspection of all the electrical components for damages. You may find blown fuses, burned or corroded connectors, bent pins, short wires etc. Make sure you also check the vacuum lines and hoses for any blockages, or damages. Repair or replace everything as needed.
It’s now time to focus on the EVAP system. Be thorough and see if all the related components are free of obstruction and no visible damages like cracks are present. You can also check the pressure differences by locating where the EVAP gets fresh atmospheric air to introduce into its system. You may find most of these parts under the vehicle. Be careful while disconnecting and handling the hoses and pipes of the EVAP system. Any mishandling can cause for damages that may require further replacements and repairs. You can now proceed to test the sensor, refer your vehicles Technical Service Bulletin to find out the specific pinout test to be performed in order to check the functionality of the EVAP sensor.
Common Mistakes When Diagnosing the P2027 Code
- Damages present in the Fuel tank temperature sensor
- Failure of the Engine Control Module (ECM)
- Problem with wiring
