P014A
O2 Sensor Delayed Response - Rich to Lean Bank 2 Sensor 2
Moderate severity
What it means
Post-cat O2 sensor on bank 2 reacts only after delay when mixture switches rich to lean. A drifted or sluggish lambda sensor lets the mixture run lean or rich without correction — fuel economy and emissions suffer immediately.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
