Cylinder numbering and scan labels are correct. A harness survey finds two nearby connectors crossed during reassembly. Restoring the documented connector routing aligns physical response with the expected bank channels.<\/p>\n    <p>The case illustrates why a code reader alone cannot prove which physical sensor is connected. It also shows why changing both sensors would have preserved the wiring error.

For Sensor 1, document technology-correct response and plausible bank fuel control under valid conditions. For Sensor 2, document circuit\/response and the applicable catalyst-monitor context. Compare the result with the original fault; do not claim success solely because codes were cleared.<\/p>\n    <p>If the opposite bank or another sensor now sets a code, review shared supplies, connector mapping and the complete system before assuming a second independent failure. Preserve permanent codes and readiness information according to the vehicle and regulatory procedure.<\/p>\n    <p>A defensible final record names who verified the cylinder 1 source, which document revision was used, which physical connector was serviced and which data channel was checked afterward. This level of traceability is especially important when a workshop, distributor and supplier handle different parts of the claim.<\/p>\n    <p>Do not publish a Bank 1 side rule for an entire brand. Even within one make, engine families and installation orientations can differ. A brand-level article may teach the identification method, but only part-level vehicle evidence can support a fitment claim.<\/p>\n    <p>When reliable cylinder numbering or exhaust-layout data is unavailable, mark the position decision <code>DATA NOT AVAILABLE<\/code> and stop the order. Guessing a side creates avoidable installation, return and emissions-system risk. Request the VIN, engine details or an authoritative diagram rather than converting uncertainty into an implied fit.<\/p>\n    <p>For B2 or Sensor 3 applications, use the same method rather than extending a B1S1\/B1S2 rule. Bank remains tied to cylinder numbering, while sensor number must be traced through the exact catalyst layout.
