Experiencing a loose OBD2 port in your 2017 Subaru WRX can be incredibly frustrating, especially when you’re trying to diagnose a check engine light or use performance monitoring tools. A wobbly connection can lead to intermittent data readings or even a complete failure to connect with your OBD2 scanner. If you’re facing this issue, you might be tempted to immediately seek professional help. However, understanding the port’s construction and common issues might empower you to troubleshoot and potentially fix it yourself.
One common point of concern is the housing that secures the OBD2 port. Sometimes, the port itself feels loose within this housing, or the entire housing might seem weakly attached under the dashboard. While a loose housing doesn’t always equate to a faulty electrical connection, it can certainly contribute to one, particularly if the pins inside the port are also affected.
Many Subaru owners have encountered a surprisingly tight fit when trying to detach the OBD2 port connector from its housing. The connector is held in place by locking tabs, which, in some models, can be quite stubborn. Trying to remove the OBD2 port from its housing to inspect for damage or improve the connection can become a minor struggle.
If you decide to attempt removing the OBD2 port from its housing in your 2017 WRX, be prepared for a potentially fiddly task. The locking tabs are often recessed and require simultaneous depression to release the connector. Using a small screwdriver or a similar tool can be helpful to carefully depress these tabs. You’ll likely need to depress one tab slightly, then the other, gently rocking the connector to inch it out of the housing. Patience is key, as forcing it could damage the connector or the housing.
After removing the connector from the housing, inspect the pins within the OBD2 port itself. A loose connection might stem from bent or damaged pins. While removing the connector from the housing alone won’t magically fix internal pin issues, it allows for a closer inspection. If you suspect pin damage, carefully examine them for any misalignment or breakage.
If the connection remains unreliable even after ensuring the port is properly seated in its housing, consider using an OBD2 extension cable. While it might seem counterintuitive, sometimes an extension cable can provide a more secure fit with your OBD2 reader, especially if the issue is related to slight variations in connector dimensions. If an extension doesn’t resolve the problem, the next step might involve examining the pins at the back of the OBD2 port connector itself.
To access the pins from the back, you might need to carefully unclip the white plastic retainer on the rear of the OBD2 port connector. Once unclipped, you can investigate if the pins are securely seated or if they require repair or replacement. However, proceed with caution if you decide to disassemble the connector further, as these components can be delicate.
In conclusion, a loose OBD2 port in your 2017 Subaru WRX can be addressed through careful troubleshooting. Start by checking the housing, then inspect the pins, and consider an OBD2 extension cable. If necessary, cautiously explore accessing the rear pins for further inspection or repair. Remember to exercise patience and avoid forcing any components to prevent damage. If you’re uncomfortable with any of these steps, seeking assistance from a qualified mechanic is always a prudent choice.
