P110D — Throttle Position Sensor A and B Circuit Range/Performance Bank 1

What do Bank and Sensor mean?

Bank 1 is the side containing cylinder 1. Bank 2 is the other side on V or flat engines; inline engines have only Bank 1. Cylinder numbering depends on the engine, so check the manufacturer’s layout.

For exhaust oxygen sensors, Sensor 1 is upstream, closest to the engine; Sensor 2 is downstream, after the catalyst. Confirm the exact sensor layout in the vehicle’s service information.
