Previa Parking Aid Stopped Working Suddenly

[wifeysprevia]

My wifes 2004 Previa TSpririt had Toyota Parking sensors fitted AFTER purchase and has always worked fine, until suddenly she put in reverse and it stopped! Any ideas? have checked fuses and all ok, assumme they run off the reverse lights which work fine. Any help would be most appreciated.

Hello and welcome to the forum.

If you have a multimeter, then perhaps check to see if there might be a broken wire/loose connection on the circuit. Corrosion at a joint as well might knock them off. I'm stating the obvious. I wouldn't have thought as an aftermarket addition it would be too complex.... sometimes with accessories added later, its the earth connection that has failed. Are they a Toyota fit?

Good luck.
