Review on πŸ”Œ Denso 234-4744 O2 Sensor by Allen Hart

Revainrating 5 out of 5

Good sensor for a good price.

My '06 Dodge Dakota had codes P0420 and P0430 (Catalytic Converters Below Efficiency). Decided to replace the catalytic converters. It turned out that the old O2 sensors were worn out. After installing four new Denso O2 sensors, the codes disappeared. Cheap repairs for less than $100 (all four sensors) instead of replacing catalytic converters ($500-$1,000).

Pros
  • Cool Product
Cons
  • Something Different
