### ⭐ 1.0 out of 5 stars







  
  
    Leads too short and did not work properly.
  

*by J***N on Reviewed in the United States on June 5, 2024*

The wire leads are about 5 inches too short compared to the OEM parts. Once I spliced the wires, the check engine light went off but the truck was running extremely rough. I replaced this with a dynsco brand sensor and solved the issue.
