Review on πŸ” Denso 234-9003 Air-Fuel Ratio Sensor by James Richardson

Revainrating 5 out of 5

Fits Gen1 3.4L Taco

I always use Denso brand sensors and have never had a problem with them. Make sure you check the PN as Amazon may offer the -9001 version as a 'common bought together' item that 'works' but doesn't fit because the cable is too short. Don't forget to lock the studs for easier replacement after the next 100,000 miles. This will help eliminate the P420 CEL code and possibly P171.

Pros
  • This is amazing
Cons
  • Only available in white
