How to Use Audio Motor Profile (AMP)

This gives you an additional layer of confidence in the vehicle’s mechanical condition beyond what photos and text can convey.

Steps

  1. Click a vehicle card in the Marketplace to open the listing.
  2. Select Condition Report to open the full inspection report.
  3. Scroll to the AMP section within the report.
  4. Press Play to listen to the engine recording.
  5. Use the playback controls to pause or replay the audio as needed.

What to expect

The AMP recording captures the engine running under controlled conditions at the time of inspection. You can hear idle quality, any unusual sounds (ticks, knocks, rattles), and general engine health. This is especially useful for evaluating higher-mileage units or vehicles where mechanical condition is a key factor in your bidding decision.

Troubleshooting

No AMP section appears in the Condition Report. AMP is not available on every vehicle. Availability depends on the inspection type ordered by the seller. If AMP is not listed, it was not recorded for that vehicle.

Audio will not play. Check that your device volume is on and that your browser allows audio playback. Try a different browser or the ACV mobile app if the issue continues.
