02 4Runner with P0500 code

Question

Looks like this topic has been well covered but what I’m trying to figure out is how it happened. I put a new radiator in the truck and when I started it back up the dash lights came on brake, vsc, trac, abs, and now check engine. Does the speed sensor harness run anywhere near the radiator? Is it possible I disconnected or severed the wire? Would get coolant on the sensor somehow make this happen?

Probably accidentally disconnected it. The speed sensor is on the transmission output shaft.

Symptoms of P0500 code:

Loss of anti-lock brakes with light on dash being lit.
Speedometer may not read accurately 
Automatic transmission may shift erratically

Possible causes:

Vehicle speed sensor not reading due to bad or missing connection 
 PCM not configured for size of tires.
