| 7. Insert sensor circle side into the big hole opening (circled in red)
8. Apply a dab of Blue Loctite to the bolt and tighten the bolt down. Make sure the sensor is not loose as oil will leak out if the bolt is not tight.
9. Plug back in the old sensor cable
10. To see if you did this correctly and for 2001 and newer cars, to reset the Service Engine Soon (SES) light:
a. Insert key into ignition and allow the diagnostic to complete before starting the engine.
b. Drive a little bit, stop and shut off engine.
c. Do this twice and on the 3rd time you start the car, the SES light should turn off.
d. If the SES light is still on, you may have to manually RESET the SES light.
Hope this helps y'all with this DIY
