Engine Controls - O2 Sensor/Cylinder Bank Designations

SOURCE: Kia PitStop

TITLE: V6 Sensor Designations and Cylinder Numbering

APPLIES TO: All V6 models

SERVICE TIP:






- Sensor 1 designates the sensor is before the catalytic converter.
- Sensor 2 designates the sensor is after the catalytic converter.
- Bank 1 designates the sensor is on the bank with cylinder number 1.
- On Kia V-6 engines, bank 1 (cylinder 1) is the firewall side of the engine.
- As a rule of thumb on a V-style, cylinder 1 is always farther forward on the engine than cylinder 2.
