Check engine light just came on

Hello, I recently replaced the crankshaft sensor and today the check engine light came on. Got home and checked the codes and it said PO158, bank 2 sensor 2, circuit high volts. I have a 2001 Wrangler 4.0L with the 2 canister cats and 4 O2 sensors. Any help would be appreciated. Thanks.

Knock a connector loose when you replaced the crank sensor? Or wire touching the exhaust pipe and melting, causing a short to ground?

How long after the crank sensor did the cel come on? Could be unrelated and you just had an o2 sensor go out.
