- Inspected check engine light is not illuminated road tested vehicle seems lower on power then normal. Pulled code p0150 bank 2 sensor 1 oxygen sensor circuit. Looked at freeze frame showed fuel trims within +5 to -5 long and short term. Watched bank 2 sensor 1 on scan tool, found it to be reading the exact same as bank 1 sensor 1 and fuel trims are normal, harness visually ok. All oxygen sensors look original and never been replaced, not sure if low power complaint is related to oxygen sensor code or not.
