Hi Folks, Have a 2012 Honda Odyssey which began throwing a Check Engine Light and Check Oil Light. My scanner revealed code P0522 which I took to be an oil sensor. Sooooo.it is my wife’s van. Took it to dealer and they came back with a bad oil Pressure SWITCH at $302.00 ( $71 part/rest labor) . Then the next morning they text her ohhhh…after running further diagnostics it looks like it is the oils sending unit and that is $505 ( labor $210.00/unit $293/O ring $1.75). So I said no… grab the car and let’s regroup… which she did). So it says on the diagnostic report I looked at ROCKER ARM OIL PRSSURE SENSOR A. So basically the sending unit is the same as the oil “sensor” (which we thought all along). Is this something I can do myself? I have fixed a fair amount of things over the years on cars and want to do it myself if possible. Appreciate your time! Kevin ---

Another possible and more ominous cause could be engine wear or a partially plugged oil passage all depending upon vehicle mileage and oil change regimen. Granted, dealer parts over the counter are generally higher but 2 to 3 hundred sounds a bit steepish. Either one maybe 30 to 50 at the local parts house. Guessing at the cost is all. No reason this can’t be a DIY job IMO. ---

Not sure on a Odyssey but on a Pilot it’s a ten minute job. You might try and see if you easily access the switch before you order the part. ---

Hey thanks for the replies appreciate it!. I thought the Odyssey had 3 sensors from the little I have been able to find on it. Since it threw code P0522 this might indicate the one below the car near the oil filter ( Of course couldn’t be up top…) That’s what I am trying to determine…Thanks! Kevin ---

The code indicates a low engine oil pressure value. That’s the oil pressure sensor by the oil filter. > **[P0522 OBD-II Trouble Code: Engine Oil Pressure Sensor/Switch Low Voltage](https://www.yourmechanic.com/article/p0522-obd-ii-trouble-code-engine-oil-pressure-sensor-switch-low-voltage-by-valerie-johnston)** > > P0522 code definition P0522 is the universal OBD-II code for Engine Oil Pressure Sensor/Switch Low Voltage.

Awesome. Appreciate the information! I am having trouble finding information online on how to change it out on a Honda Odyssey but one step at a time… Best, Kevin
