Can an OBD Adapter cause problem with dash cluster gauges?
I’ve been having an intermittent issue with the dash cluster gauges on my 05’ F250 shutting off a few seconds after I start the truck (might happen a couple of times a month). The Tach, Speedo, and water temp gauges die….but the oil pressure, fuel, trans temp, and boost gauge keep working. I also get the wrench and check engine lights as soon as the gauges die. I will also get a TBC fault at the same time.
Usually shutting the truck off and restarting it fixed the issue. The gauges always work for 2-3 seconds after I start the truck…..then after a few seconds, they die and I get the fault.
I had it happen again to me this weekend, and while the truck was idling, the gauges were dead, and I was getting the faults….I tried using my Torque PRO app to scan for codes. Well, the cheap $10 ELM327 OBD Bluetooth Adapter (that I always leave plugged into the OBD connector on the truck) would not hook up to my phone for some reason…..so I unplugged it to see what was going on.
As soon as I unplugged the OBD adapter, I heard a beep from under the dash…….the faults on the cluster all cleared, the gauges all sprang back to life. Even after plugging the adapter back in, everything is fine.
I’m just wondering if anyone else has had an issue like that. Is it possible for an OBD adapter to cause problems like that with the dash cluster and gauges?
