Multiple sensor records can sometimes reflect a common electrical dependency. The wiring information must establish that relationship; similar code descriptions alone do not prove a shared supply.
Build a circuit-based picture
Keep the full scan and identify which symptoms occur together. Ask the technician which common connections the actual vehicle uses and what measurements support the hypothesis. A shared-circuit fault and several independent faults remain different possibilities.
Do not disconnect devices at random or replace all named sensors. The correct diagnostic procedure should guide isolation and protect the circuits. After repair, verification should include the affected functions and relevant operating conditions, rather than only confirming that one sensor now produces a plausible reading.
