What is OBD-II Code P2A60 – Alternative Fuel Tank B Level Sensor Range/Performance
The technology and functionalities of modern vehicles have significantly improved over the years due to the integration of various electronic components, mostly controlled by on-board computers. However, these complex systems can result in issues that require technical expertise to resolve. One of the ways to identify potential issues is through the use of On-Board Diagnostics (OBD) systems, which identify any problems or faults in the vehicle.
OBD-II (On-Board Diagnostics), in particular, provides detailed information on engine performance, fuel economy, and emissions. This information can be accessed using a scanner tool that reads OBD-II codes, which provides insight into the problem. One of the codes that can be detected is P2A60, which is related to the Alternative Fuel Tank B Level Sensor Range/Performance. In this article, we will discuss what this means, what causes it, and how to repair it.
What is OBD-II Code P2A60?
OBD-II Code P2A60 indicates that the Alternative Fuel Tank B Level Sensor has detected a deviation in the sensor signal’s expected range or performance. This code only applies to vehicles with alternative fuel systems such as those that use CNG (Compressed Natural Gas) or propane as fuel. The code refers to the B fuel tank; hence, it is specific to vehicles that have two fuel tanks, with the second one being the alternative fuel tank.
The vehicle’s computer system monitors the fuel level in the alternative fuel tank. The level sensor sends a signal to the computer system, which confirms the amount of fuel available in the tank. However, when the sensor signal is outside the expected range, the computer system may store the P2A60 error code.
What Causes OBD-II Code P2A60?
Several factors can cause an Alternative Fuel Tank B Level Sensor to send a signal outside the expected range. The most common causes include:
1. Faulty Sensor: A faulty Alternative Fuel Tank B Level Sensor can send the wrong signals to the vehicle’s computer system.
2. Damaged Wiring: Damaged wiring in the sensor circuit can cause the signals to be interrupted or distorted, leading to the P2A60 error code.
3. Fuel System Issues: Fuel system issues such as a clogged fuel filter, damaged fuel injectors, or a broken fuel pump may cause the fuel tank to send incorrect signals to the level sensor.
4. Software Issues: Software issues in the vehicle’s computer system can cause the level sensor to malfunction.
How to Fix OBD-II Code P2A60
Once OBD-II Code P2A60 is detected, it is essential to determine the root cause of the problem. Here are some of the steps that mechanics can take to diagnose and repair the issue:
1. Check the Fuel Tank: The first step in diagnosing the P2A60 error code is to check the fuel tank for any signs of damage, leaks, or blockages.
2. Check the Sensor Wiring: Mechanics will need to check the wiring and connectors in the sensor circuit for any damages, oxidation, or distortion. In case of any damages, the wiring or connectors should be repaired or replaced.
3. Replace Faulty Sensor: If the level sensor is faulty, it will need to be replaced. The new sensor needs to be calibrated before use and should be installed, ensuring it is correctly positioned.
4. Verify the Computer System: The computer system that is responsible for monitoring the fuel system should be verified, and any software issues should be addressed. In some cases, updating the computer system’s software may be necessary.
5. Check Vacuum System: Check and diagnose the vacuum system for any leaks. Any leaks found should be repaired.
6. Fuel System Diagnostics: Check fuel delivery system at Common V with a manufacturer specific command, if fuel delivery system is found OK by this test, perform a dedicated test for the fuel delivery system.
