What P1162 means on specific makes
Honda / Acura CAUTION
The upstream A/F sensor responds too slowly to mixture changes, so the PCM flags it as aging. Indicates the sensor signal is lazy, not necessarily fully dead.
- Worn/aging A/F sensor ($90-250)
- Sensor contamination
- Exhaust leak near sensor
Check first: Watch the A/F sensor live data response during throttle changes; replace if sluggish.
