Bus Troubleshooting

1. “All of my sensors are sending back bad data, and when I checked to see if they were working with a ProCheck, all of them were.”

If all of your sensors are working but sending back bad data, chances are that the problem lies not in your sensors but in your bus. To test your bus, take a multimeter and set it to read resistance (ohms). Touch one of the ends of the multimeter cable to the first port on your bus. If there is no break in communication, the display should read close to zero. If there is, the display will read in the millions or be unable to obtain a value. If this should happen, you may have to re-solder that port’s connection. Repeat this step on all other ports. If even one of the ports on the bus is not communicating, the bus will not function correctly and your sensors will continue sending back bad data.
