I have an O2 heater sensor code p0141 in my 97 Marquis and I'm wondering if there's a fuse that protects the heater circuit and if so can someone tell me where it is thank you

No fuse for that. Totally controlled by the PCM. You can check the wiring harnesses between the ECM and the O2 connector to make sure there's good contact. Especially the ones under the brake booster.

Grab the wire from the O2 sensor. Follow it back to its harness. Follow that harness back to the next harness. There should only be two in line from the O2 sensor to the PCM IIRC.
