Review on Enhance Engine Efficiency with Denso 234-4077 Oxygen Sensor by Adam Boudreau

Revainrating 5 out of 5

Worked on my '98 Dakota

I left my check engine light on for about 100,000 miles, ran the code and it came back with an emissions code - it occurred to me it was catalytic efficiency. I figured I'd try replacing the sensors before spending the big bucks on a catalytic converter. Well it worked. It's been 2 years and the check engine light hasn't returned! Note: I swapped the front and rear sensors. It was a no-brainer, not my truck. only lasted 30 minutes or so.

Pros
  • Easy setup
Cons
  • Requires outlet
