Experiencing a loose OBD2 port in your 2017 WRX can be a frustrating issue, especially when you need to run diagnostics or connect any OBD2 devices. A wobbly or unreliable connection can prevent proper communication between your car’s computer and diagnostic tools, leading to headaches and delays in identifying potential problems. This article will explore the common causes of a loose OBD2 port in a 2017 WRX and guide you through troubleshooting steps to resolve this issue.
Many 2017 WRX owners may encounter a situation where their OBD2 port feels loose within its housing. Sometimes, the issue isn’t just the housing, but the connector itself. Removing the OBD2 port from its housing might seem like a first step to diagnose the problem, but as one Subaru owner discovered, it might not directly solve connectivity issues.
Initially, attempting to detach the OBD2 port connector from its housing can be challenging. The locking tabs that secure the connector are often recessed and require a tool for effective manipulation. Trying to depress these tabs with just fingers or a simple key can prove difficult. Using a small screwdriver can be helpful to depress one tab at a time. The trick is to slightly rock the connector while keeping one tab depressed, then quickly move to the other tab before the first one clicks back into place. This process may require patience and multiple attempts, and as some find, having extra hands would certainly make this task easier.

Once the OBD2 connector is successfully removed from its housing, you can examine it more closely. However, as was found in a real-world scenario, separating the connector from the housing alone doesn’t guarantee improved connectivity with an OBD2 reader. The root cause of a “2017 Wrx Obd2 Port Loose” issue often lies deeper than just the housing. It’s essential to investigate the pins within the connector and the port itself for any damage or looseness.

A loose OBD2 port can result from several factors:
- Bent or Damaged Pins: Over time or through repeated use, the pins inside the OBD2 port or on your OBD2 reader can become bent or damaged. This can lead to a poor connection and the feeling of a loose port.
- Loose Connector within Housing: While the housing is designed to hold the OBD2 port securely, the connector itself might become loose within the housing due to wear and tear or manufacturing tolerances.
- Wiring Issues: Although less common for a physically “loose” port feeling, issues with the wiring behind the OBD2 port could also manifest as intermittent connectivity, which might be mistaken for looseness.
To further troubleshoot a loose 2017 WRX OBD2 port and connectivity problems, consider these steps:
- Inspect the Pins: Carefully examine the pins inside the OBD2 port for any signs of bending or damage. Use a flashlight for better visibility. If you notice bent pins, you might be able to carefully straighten them with a very small tool, but proceed with caution as pins are delicate.
- Try a Different OBD2 Reader: Rule out the possibility that the issue is with your OBD2 reader. Trying a different, known-good OBD2 reader can help determine if the problem is with your device or the car’s OBD2 port.
- Use an OBD2 Extension Cable: As a temporary measure or diagnostic step, an OBD2 extension cable can sometimes provide a more stable connection if the issue is related to the reader not seating properly in the port. While it might not fix a genuinely loose port, it can help isolate connection problems.
- Examine the Connector Back: If you suspect internal issues with the connector itself, you can further disassemble it. Often, a white clip on the back of the OBD2 port connector needs to be removed to access the wires and pins. However, proceed with caution if you decide to remove pins as they may have their own locking mechanisms.

If after these steps, your 2017 WRX OBD2 port remains loose and unreliable, it may be necessary to consult a professional mechanic or a Subaru dealership. They can perform a more thorough diagnosis of the OBD2 port and related wiring to pinpoint the exact cause and recommend appropriate repairs or replacements. Addressing a “2017 wrx obd2 port loose” issue promptly is important to ensure you can effectively monitor your vehicle’s health and perform necessary maintenance.
