Experiencing the frustration of an “Obdii Torque Adapter Not Found” error while trying to diagnose your car with the Torque app is a common issue for many DIY car enthusiasts. You’ve plugged in your Bluetooth OBD adapter, it seems to have power, but your Android car stereo or phone just won’t connect to your car’s computer. This guide will walk you through the common causes and troubleshooting steps to get your OBDII adapter working and reading your car’s data again.
Common Causes for OBDII Adapter Connection Issues
Several factors can prevent your Torque app from recognizing your OBDII adapter. Let’s explore the most frequent culprits:
1. OBDII Adapter Malfunction (Less Likely in This Case)
While it’s always a possibility, if you’ve tested your adapter on other vehicles and it worked flawlessly, as in your case, the adapter itself is likely not the primary issue. However, it’s still worth briefly considering if the adapter has intermittent connection problems.
2. Torque App Configuration and Protocol Mismatch
The Torque app needs to be correctly configured to communicate with your car. A common oversight is the automatic protocol detection failing. If the app is not set to the correct OBDII protocol for your vehicle, it won’t be able to establish a connection.
3. Power Supply Issues to the OBDII Port
The OBDII port in your car needs power to operate correctly and communicate with the adapter. A blown fuse or wiring problem can cut off power to the port, preventing the adapter from being recognized. You mentioned your cigar lighter not working, which is a significant clue. Often, the OBDII port and cigar lighter share the same fuse or power circuit.
4. Bluetooth Connectivity Problems
Although your Android car stereo shows the adapter as connected via Bluetooth, there might be underlying issues preventing data exchange. Interference, incorrect pairing procedures, or Bluetooth stack glitches can sometimes cause connection problems even when devices appear paired.
Step-by-Step Troubleshooting for OBDII Adapter Connection Failure
Let’s systematically troubleshoot the “OBDII torque adapter not found” problem:
-
Verify OBDII Port Power: This is crucial, especially given your cigar lighter issue.
- Check the Fuse Box: Locate the fuse box diagram for your car (usually in the owner’s manual or online). Identify the fuse related to the cigar lighter or auxiliary power outlets. Even though you checked with a tester, visually inspect the fuse for any signs of being blown (broken wire inside). Sometimes a fuse can appear okay but still be faulty. Try replacing the fuse with a new one of the correct amperage, even if the old one looks fine.
- Test the OBDII Port Directly: Use a multimeter to check if the OBDII port is receiving power. Pin 16 of the OBDII port should have 12V power. If there’s no power here, you’ve likely found the root cause.
-
Torque App Protocol Settings:
- Force Protocol Selection: In the Torque app settings, navigate to “OBD2 Adapter Settings” or “Vehicle Profile”. Instead of “Automatic,” try manually selecting different OBDII protocols. Common protocols include ISO 9141-2, ISO 14230-4 (KWP2000), and ISO 15765-4 (CAN). Experiment with these to see if one allows a connection.
-
Bluetooth Connection Reset:
- Forget and Re-pair: In your Android car stereo’s Bluetooth settings, “forget” or “unpair” the OBDII adapter. Then, re-initiate the pairing process. Ensure you follow the adapter’s instructions for pairing.
- Test with Another Bluetooth Device: If possible, try connecting the OBDII adapter to a different Android phone or tablet to rule out any specific Bluetooth issues with your car stereo. You’ve already done this with an Android phone, confirming the issue is likely with the car itself, not just the stereo.
-
Inspect OBDII Port Condition:
- Physical Damage: Check the OBDII port in your car for any bent pins, debris, or damage. A physically damaged port can prevent proper connection.
-
Consider Wiring Issues (If Fuse Replacement Doesn’t Work):
- Cigar Lighter Wiring: Since your cigar lighter is also not working, there might be a break in the wiring leading to both the cigar lighter and OBDII port. This is more complex and might require a professional technician to diagnose and repair.
Conclusion: Focus on Power to the OBDII Port
Based on your description, the most probable cause for the “OBDII torque adapter not found” issue is a lack of power to your car’s OBDII port, likely linked to the non-functional cigar lighter. Thoroughly checking and replacing the relevant fuse is the first and easiest step. If the fuse is not the problem, investigating the wiring for both the cigar lighter and OBDII port will be the next logical step. Resolving the power issue to your OBDII port should allow your Torque app and adapter to connect and start providing valuable diagnostic information about your vehicle.
