Works Great

  • Fits fine and is the correct sensor, but failed within 1 day
Install went fine and everything was ok for the first start. After the first start the CEL came on and starts took longer and a backfire would occur. Sometimes the car wouldnt start.

  • Spend the extra money
It’s the correct part for my truck but it was no good. Engine wood back fire and was hard to start. Had to put the old one back in to run. I wouldn’t recommend it.

  • BUYER BEWARE
Buyer beware. I won’t buy a Walker product again. Bad part received out the box.. Was changing out sensors since intake gasket off. Had a long crank issue. Only thing that would have caused this issue was this part. Put the old one back in took the issue away.
