Review on πŸ”₯ Heated Oxygen Sensor for GM Original Equipment: Buick Cadillac Chevrolet GMC Hummer Oldsmobile Pontiac (Replaces 234-4229) by Paul Barnes

Revainrating 3 out of 5

solenoids. I hope they work the way my garage says they don't have the right plugins like they do.

The price is right. After looking at the reviews, people ask questions upstream or downstream. When I bought them they said they were compatible with both. I installed them very carefully, my check engine light is off but the codes are still pending as I am waiting for the ECM to complete the circuit. For now I'll say they aren't ready, as are a few other valving/solinoids.

Pros
  • Few competitors
Cons
  • Not sure
