## Questions & Answers

**Q: is the O-ring included ? Is the front and rear pressure switch exactly the same part? whith which device can i reset the code?**
A: The o-ring is not included. You need 91319-PAA-A01 o-ring.

**Q: What does this sensor fix? Where is it located? The oil light blinks when I turn on the 2008 Ody. I'm assuming is a sensor. Which 1?.**
A: There are 3 oil sensors on the engine block. We have a 2012 Ody. This sensor will fit the front and rear sensor slots but not the bottom. The bottom runs about $150 and is much more difficult to replace. The two sensors on top (front and rear) are very easy to get to. Just search for a video on Honda Odyssey oil sensor fix. Also, if you replace them, make sure you clean the terminals as they can get corroded. And get the o-rings for the sensors as the part does not come with it.

**Q: Is this same oil pressure switch for the honda pilot ?**
A: Yes, it fit my 2013 pilot.

**Q: Are the front and rear switch the same part??**
A: Yes , they are the same part. Just be careful not to over tighten when replacing.
