We are here to help you understand the issue and also resolve it so that you can get rid of the OBD code. This code is set by the Powertrain control module (PCM) when it notices that the Fuel Tank Temperature sensor is no longer able to monitor the fuel temperature in the tank. It’s defined as; Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Circuit Low Voltage. Read more in this article about the P2026 code.

1. Powertrain Control Module - It is the brain of your vehicle and hence is responsible for doing contant checks and making sure the various systems of your vehicle are working in sync. The PCM sets the P2026 code, so make sure there are no issues with it. You can go for replacement if the problem is beyond repair.

2. Purge Control Valve Solenoid - The amount of fuel vapor that is purged from the charcoal canister is controlled by this solenoid and it is part of the EVAP system. AVoid damage to the EVAP due to a faulty solenoid and don’t delay repairs or replacement.
3. Evaporative Emission Control System (EVAP) - Its prime task is to prevent harmful gasoline vapors to be let out into the atmosphere. In order to get rid of the P2026 error you may have to repair or replace the EVAP system. Find the perfect replacement at PartsAvatar. Order online easily and get doorstep delivery.
4. Fuel Vapor Temperature Sensor - Monitors fuel vapor temperature in the charcoal canister or fuel tank. If you have observed any problem during diagnosis, then repair them or replace the sensor so that the P2026 code can be resolved.
5. Fuel Tank Temperature Sensor - Informs the Engine Control Unit if it has to adjust the amount of fuel it injects, based on the temperature of the fuel. A malfunctioning sensor results in the wrong amount of fuel being injected. Repair or replace it as needed.
6. Engine Control Module - The processing unit of your vehicle, it also interchangeably known and the PCM. Problems present in the ECM can damage the whole engine, so don’t take them lightly and ensure repairs or replacements are done as needed. You can find the perfect ECM for your car on PartsAvatar. Order online today.
7. Emission Control System - Reduces the discharge of noxious gases from the internal-combustion engine and other components. Repair any issues you have found immediately, as a bad emission control system can cause extensive damage to the engine.

If you are facing OBD error code P2026, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• The state/provincial emission test has not been cleared
• Malfunction indicator light is on
• Decrease in fuel economy
• Odd smell of the Fuel
• Fuel filling is showing problem like taking too much time, or pulling the trigger on gas pump is difficult.

If you want to easily diagnose the P2026 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 P2026 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.

It’s time for a thorough visual inspection of all the electrical components for damages. All blown fuses, burned or corroded connectors, bent pins, short wires etc. will have to be repaired. Make sure you also check the vacuum lines and hoses for any blockages, or damages. Repair or replace everything as needed.

Move 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 P2026 Code

• Malfunction of the Fuel tank temperature sensor
• Malfunction of the Powertrain Control Module (PCM)
• Wiring is having issues
