What is OBD-II Code P2A96 – Alternative Fuel Tank Select Valve B Control Circuit Performance

If you are a car owner, it’s essential to understand OBD-II codes and their meanings. OBD-II (On-Board Diagnostics) codes are error codes that show up in your car’s on-board computer when there is a problem with any system or component of your car. Each code is composed of a five-character alphanumeric sequence. In this article, we will be discussing OBD-II Code P2A96 – Alternative Fuel Tank Select Valve B Control Circuit Performance, what it means, and how it can be fixed.

What is OBD-II Code P2A96?

OBD-II code P2A96 means that there is an issue with the Alternative Fuel Tank Select Valve B Control Circuit Performance. It is applicable for vehicles that run on biodiesel, ethanol, or natural gas. The code appears when the powertrain control module (PCM) detects a problem with the fuel tank control valve, which directs fuel to the right fuel tank.

The Alternative Fuel Tank Select Valve B is one of two components that work together to provide fuel to a vehicle’s engine. In the event that the primary fuel source fails or is depleted, a secondary fuel tank is employed. That’s when the Alternative Fuel Tank Select Valve B is needed. It is an important component in the engine system as it is responsible for controlling fuel flow between the two tanks. When the control circuit performance of this valve is erratic, it triggers an OBD-II code P2A96.

Symptoms of OBD-II Code P2A96

There are a few symptoms to look out for if you suspect an OBD-II code P2A96 has been triggered in your vehicle. The most prominent symptom is the “check engine light” on your dashboard turning on. Other symptoms that may indicate the presence of this code include:

– Reduced fuel economy
– Rough engine idle
– Difficulties starting the engine
– Decreased horsepower and acceleration
– Increased emissions

Causes of OBD-II Code P2A96

There are a few causes of an OBD-II code P2A96, which include:

– Corroded or loose wiring: Corroded or loose wiring in and around the Alternative Fuel Tank Control Valve circuit could cause poor connections and lead to error codes.
– Malfunctioning Fuel Tank Select Valve: The Alternative Fuel Tank Select Valve B might be failing or not working properly, leading to erratic performance and triggering OBD-II code P2A96.
– Issue with the Fuel Level Sensor: The fuel tank level sensor is responsible for detecting when the fuel level drops. If there is an issue with this component, it could trigger OBD-II code P2A96.
– Problem with the PCM: The powertrain control module (PCM) that oversees the Alternative Fuel Tank Select Valve’s operations might be malfunctioning or dealing with software errors, resulting in the code’s triggering.

How to Fix OBD-II Code P2A96

Fixing OBD-II code P2A96 requires a diagnostic scanner, specialized equipment, and an experienced auto mechanic. To repair the issue, the mechanic will take the following steps:

1. Inspection: The mechanic will inspect the wiring and connections around the Alternative Fuel Tank Select Valve B Control Circuit to check for rust or loose connections, which may have caused the code to appear.

2. Testing the Fuel Tank Control Valve: The next step is to test the Alternative Fuel Tank Select Valve B. The valve will be tested to assess its condition and correct malfunctions.

3. Examining the Fuel Level Sensor: The mechanic will also evaluate the fuel level sensor to assess its condition and determine whether it is malfunctioning.

4. PCM operation check: Finally, the PCM’s operation will be examined to ensure it is functioning correctly and this may include some computer diagnosis.

5. Any components that are found to be defective will be replaced, and any wiring issues that have been identified will be repaired.
