Most Pz071 diagrams come with a diagnostic flowchart. For example, if the "Engine oil pressure warning light stays on," the diagram will direct you to check continuity between Pz071 Pin 15 and the oil pressure switch.
Switched 12V+ / Accessory (Red) – Triggers the unit to turn on when the ignition is in the 'ACC' or 'ON' position.
The diagram includes small circles with "SP" numbers. These are splice points where multiple wires join inside the harness. If one sensor fails but a second on the same splice works, the issue is likely the sensor itself, not the harness.
