Toyota Crown Rev front oxygen sensor 89467-30010 genuine location replacement

This upstream oxygen sensor directly replaces OEM numbers 89467-30010 and is compatible with 89467-30030, 8946704020, 894670C010; universal compatibility with no wiring changes or repositioning required. Core function is to monitor exhaust oxygen content and feed ECU to accurately control fuel injection; suitable for Toyota Crown and UZ Pri or Verossa models with 1GR or 3GR engines. Replacing resolves high fuel consumption, unstable idle, and throttling issues; emissions return to normal. If cold start is hard, check engine light on, or exhaust emits black smoke, oxygen sensor aging is likely; replace.
