Error Codes P0345 and C1201 4Runner (4th gen)

Engine wouldn't start.

• Heard a click, but no turn over.
• Lights on the dash came on and they were bright. Radio worked.
• Ended up jump starting and drove to auto store.
• Bought and installed new Duralast Gold Battery 24F-DLG Group Size 24F 750 CCA.
• Used their scan tool which gave following codes.

Error P0345
Camshaft Position Sensor 'A' Circuit (Bank 2)

Error C1201
Brake Boost Sensor Circuit

For P0345

• Ordered replacement Camshaft Position Sensor - Replace 2CAM0057, 180-0499 Compatible with Toyota, Lexus (Amazon product id: B096QHS6WP)
• Watched this video on replacing the Camshaft Position Sensor for the 4th gen 4Runner

For C1201

• Could be gas gap problem again? Already on my 4th OEM gas cap.

One website says

• Large Evaporation system leak
• Loose/faulty Gas cap

I mean the 4th gen brake master cylinder is in the engine bay and has electronic connections on it... Have you checked all those for loose wires/bad connections/other visible issues?
