toyota prado parking sensors not working

If your Toyota Prado’s parking sensors have downed tools, don’t panic—start with the obvious.

• Dirt, mud or bug splatter on the sensor faces; clean them and try again.
• “Tow/Trailer” mode or parking sensor mute toggled in the dash or head-unit settings.
• Failed sensor (no faint ticking when touched), or a cracked bumper clip throwing off alignment.
• Water ingress or corroded connectors in the rear bumper loom after heavy rain or a pressure wash.
• Blown fuse or broken wiring after a towbar install or off-road scrape.

Cycle the ignition, select reverse, and listen for the tell‑tale beeps; a constant tone usually means a single sensor has carked it.

If cleaning and menu checks don’t fix it, a quick OBD scan at a decent auto sparky will pinpoint the guilty sensor faster than you can say “shopping‑centre carpark”.
