PM Sensor

Hi everyone. I have a 2020 F350 that I put a welding bed on. I hardwired all my tail and marker lights to the factory harness. Now I get a CEL and code U02A3 which is lost communication with PM sensor. Trying to figure out how to solve this issue. I haven’t bought or replaced the sensor yet as with only 38k miles I can’t imagine that would be bad unless it may have shorted out or something. Truck runs great with light on. Any help would be appreciated. Thanks!

It could just be a bad sensor. If you have Forscan you can test them.

I do not have forscan but will have everything next week to check it out. Was looking to see if anyone else out there put a flatbed or weld bed on there truck and ran into the same issues.
