2014 Nissan Versa Note 1.6L with P0181 and P0183 Codes After Engine Wash - Water Damage Suspected?

I recently had my leased 2014 Nissan Versa Note 1.6L taken to a detail service for a final clean before returning it. The package included an engine wash, which I agreed to. Immediately after picking up the car and turning it on, the check engine light illuminated. When I asked the staff why this happened, they explained that they performed a power wash but avoided the battery and other critical components. Using my OBD2 code reader, I detected persistent fault codes P0181 and P0183. I've been clearing these codes for two days, but they keep reappearing. Since we're in Canada with very cold temperatures, I'm concerned that water may not have fully dried and could have frozen inside the engine or fuel system. My main question is: Can the force of high-pressure water or excess moisture during an engine wash actually damage sensors like the fuel temperature sensor? Where is this sensor located — is it in the engine bay or within the fuel tank? Given that my vehicle is relatively new and the issue occurred right after a professional engine wash, I'm considering filing a claim with the detailing service. They have acknowledged they may be responsible if water damage is confirmed. Any technical insight or guidance on whether these codes are likely caused by water intrusion would be greatly appreciated! Thanks in advance!
