Review on Enhance Engine Performance with πŸš€ the Denso 234-9042 Air Fuel Ratio Sensor by Colton Scheehl

Revainrating 2 out of 5

Accurate replacement for 2004 Toyota Sienna Upstream Oxygen Sensor

The original sensor was coated white and deteriorated resulting in a lean fuel/air ratio. The spark plug center electrode insulators were almost white. The engine died when accelerating. Now the engine responds easily to the gas pedal and runs smoothly. The block was perfect for the replacement, right down to the clamp that secures the wires to the bracket from abrasion. Would buy again.

Pros
  • Easy to read control panel
Cons
  • I will add later
