P2025 OBD Error Code: Problem & Solutions

<<See All OBD Codes

This P2025 code is set when the Fuel Tank Temperature sensor fails to monitor the fuel temperature in the tank. The Powertrain Control Module (PCM) will hence set the code and he check engine light will be illuminated. If you’re struggling to figure out what to do, don’t worry we have the information you will need to resolve this code.

The P2025 code is defined as an Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Performance. The EVAP system is needs different sensors, valves and switches to maintain the emissions wanted by the engine. The Engine Control Module (ECM) monitors them and adjust them as needed by the system. The fuel vapor temperature sensor is employed by the ECM to successfully monitor the temperature of unburned vapors. These vapors are sent back to the engine, otherwise they would get expelled into the atmosphere. The components of the EVAP system are mostly plastic, hence it’s very important to ensure no damage occur to them as they’re exposed to heat all the time. These plastic parts can crack, split, break or even clog during peak winter season. This P2025 code is set when the fuel tank temperature sensor fails to function as needed.

What causes this problem with the Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Performance?

• Defects present in the EVAP sensor
• Blockage or leak within system
• EVAP fuel vapor temperature sensor wiring harness are broken or damaged
• Short Wire
• Circuit shows excessive resistance
• Malfunction of the ECM (Engine Control Module)
• Issue with the Pin/connector like corrosion, melting, burning, bending etc.

1. Powertrain Control Module - The main component of you vehicle, which is responsible for controlling the functioning of all the other components. You can try to repair the problem noticed or replace it. Replacement will need reprogramming by a professional and can be expensive. But this is important to avoid further damage to other parts of your vehicle. Find the perfect fit PCM for your vehicle on PartsAvatar and avail free shipping on orders above CAD $99.
2. Purge Control Valve Solenoid - Is responsible for controlling the amount of fuel vapor that is purged from the charcoal canister. it is part of the EVAP system and can be the reason for P2025 code. The EVAP is at risk of damage if this issue isn’t resolved so don’t delay repairs and if needed go for replacement from PartsAvatar.
3. Evaporative Emission Control System (EVAP) - Helps to prevent harmful gasoline vapors to be let out into the atmosphere. You will have to repair or replace the EVAP to get rid of the P2025 error. Find the best replacement at PartsAvatar Canada. Order online easily and receive your delivery at your doorstep in a matter of days
4. Fuel Vapor Temperature Sensor - Is responsible for monitoring fuel vapor temperature in the charcoal canister or fuel tank. Repairs or replacements can help in resolving this problem.
5. Fuel Tank Temperature Sensor - Informs the ECU to adjust the amount of fuel it injects based on the temperature of the fuel. And if it’s not functioning properly wrong amount of fuel will be injected. Get rid of the P2025 code by repairing or replacing the sensor or the damaged components.
6. Charcoal Canister - Reduced pollution by Absorbing the fuel vapor that would put to the atmosphere. Repair or replace it as needed to resolve the P2025 code.
7. Electronic Sensor - A problematic sensor can cause wrong information to be given to the PCM. The job of the electronic sensor is to pick up information about various components of the vehicle and transfer the information to the PCM. Repair or replace in order to avoid problems with how your vehicle functions.

For us our customers are everything, and that’s why we will help you to diagnose P2025 code by mentioning some important symptoms below:

Common Symptoms

• Failing the state/provincial emission test
• The Check engine light has been on since the code was set
• A considerably reduced fuel economy
• Fuel is not having the usual smell, it’s smelling odd
• Multiple issues present while filling the fuel like increase in fill up time, pulling trigger on gas pump fully is not smooth, etc.

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue you need to follow certain steps, and to solve OBD error code P2025, you will need to undergo the replacements of the following if repairs isn’t resolving the code.

• Purge Control Valve
• Purge Control Solenoid
• Charcoal canister
• Powertrain Control Module (PCM)

Apart from the fuel injector, you might need to undergo few more replacements. You might need PCM, EVAP, Fuel Vapor Temperature Sensor, Fuel Tank Temperature Sensor, ECM, Purge Control Solenoid, Charcoal Canister, Electronic Sensor and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

If you want to easily diagnose the P2025 fault code, then all you have to do is to follow the steps which are mentioned below:

Start by getting 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 P2025 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 P2025 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 verify the functionality of the EVAP sensor.

Common Mistakes When Diagnosing the P2025 Code

• The Fuel tank temperature sensor has completely failed
• Failed Powertrain Control Module (PCM)
• Multiple problems with the wiring
