Review on Honda OEM (37240-R70-A04) Oil Pressure Sensor Assembly by Richie Kotun

Code p3400 appeared on my 2013 acura rdx so I looked it up and found I needed to replace this part, ordered it and installed it in a few days. Since then there is no more error code! Best not to bring it to the store and all you need is this part, the o-ring that fits in between, a torque wrench and a 24mm deep socket. All in all it cost less than $100 and only took a few minutes to swap out and now I have the tools in case the other one fails anytime soon.
