Review on πŸ”§ Enhanced Denso 234-4012 Oxygen Sensor, Upgraded Version by David Herrera

Revainrating 4 out of 5

Works as advertised.

My Rodeo has the code "B1S1 Slow Response O2 Sensor". Using my manual power oxygen key that I bought at the same time and a liquid key, I swapped my old one for this new one and boom, no more check engine light. Didn't really solve my wandering idle problem like I was hoping. Well I'm sure the oxygen sensor isn't the only problem with this truck.

Pros
  • High marks for support and durability from testers
Cons
  • Some issues
