  • Crazy
I managed to remove the sensor with out taking the valve cover off. A ridiculous peice of engineering..

  • OEM replacement
This is a difficult part to change the old one will break upon removal it is a press fit and without specific GM removal tool you just need to force it out. The installation is easy as can just push in and it will lock in place with side tabs.

  • GM genuine...
Very nice stock replacement part. Be very careful installing if you're a DIY person... Otherwise, have it done by a professional. Smoothed out our 2017 chevrolet cruze rough idle. This valve being bad can also trigger the dreaded proverbial P1101 DTC.... Thank you, part came quickly and without damage. Happy wrencher!!!! ... show more

  • Great price for OEM product
Got this for my daughter's car but was not able to install without removing the manifold cover. Gave it to dealership who installed it as part of other work being done. Saved me time and headache.
