How to test adaptive triggers
Connect your Sony DualSense controller to your PC using a USB-C data cable, click Connect via WebHID, and select any resistance preset (Weapon, Bow, Machine Gun) to feel real-time force feedback in your L2 and R2 triggers.
Because browser Gamepad APIs can only read analog trigger pull depth (0.0 to 1.0), testing the physical geared motor mechanism requires sending raw WebHID output reports directly to the DualSense motor controller.
What each resistance mode does
Each preset tests a distinct force feedback profile: Weapon simulates a firm mechanical trigger wall followed by a sudden snap, Bow creates progressive spring tension, and Machine Gun pulsates rapid vibration kickback.
1. Weapon Mode: Engages a hard resistance wall at 20% travel that releases abruptly upon full pull.
2. Bow & Arrow: Builds smooth, continuously increasing counter-pressure from 0% to 100% travel.
3. Machine Gun: Drives the internal geared motor in high-frequency reciprocating vibration bursts.
4. Rigid Resistance: Locks the trigger at a fixed stopping point to verify holding torque.
Travel vs resistance: two separate tests
Trigger travel measures potentiometer depression depth (0% to 100%), while adaptive trigger resistance evaluates the active geared motor mechanism that pushes back against your finger.
A DualSense trigger can register full analog travel in standard gamepad testers even when its adaptive motor is stripped, jammed, or disconnected. Running our force feedback diagnostic ensures both the potentiometer sensor and the mechanical gear train are fully operational.
Signs an adaptive trigger is failing
Warning signs of adaptive trigger failure include a limp trigger that lacks resistance, loud grinding or clicking noises when motors engage, or uneven resistance between L2 and R2.
The DualSense adaptive trigger assembly contains a small plastic worm gear, a potentiometer arm, and a return spring. If the controller is dropped or the trigger is forced past its resistance wall, the plastic gears can strip or the return spring can snap, resulting in a loose, floppy trigger.
Can adaptive triggers be repaired?
Broken trigger return springs and stripped motor gear assemblies can be replaced using aftermarket repair kits, though opening the controller requires delicate ribbon cable disassembly.
If your controller is within its 1-year manufacturer warranty period, submitting an RMA claim to Sony is recommended. Export our diagnostic health certificate to include with your warranty submission.
Why no other browser tool tests this
Driving physical trigger resistance requires transmitting proprietary WebHID output reports (Report 0x02 on USB) with specific payload motor commands that generic gamepad testers cannot execute.
Most online tools only read incoming gamepad data. Our diagnostic engine implements the reverse protocol, sending active motor commands directly to the DualSense microcontroller in real time.
Frequently Asked Questions
How do I test PS5 adaptive triggers?
Connect the DualSense by USB and run each resistance mode on this page. You should feel distinct resistance profiles in L2 and R2 â weapon gives a firm break point, bow builds tension.
Why is only one adaptive trigger working?
The two triggers use separate motor assemblies, so one commonly fails alone. Uneven resistance between L2 and R2 is a hardware fault, not a setting.
Do adaptive triggers work over Bluetooth?
Resistance commands are sent reliably over USB. Bluetooth support varies by report mode, so use a cable for testing.
Can I turn adaptive triggers off?
Yes, in PS5 accessibility settings, and many games offer their own toggle. Turning them off does not fix a failed motor.
Are adaptive trigger faults covered by warranty?
Trigger motor failure is a hardware defect and is normally covered. Export the report from this page as evidence before contacting support.
