Review on Enhance Engine Performance with Standard Motor Products PS-483 Valve Timing Oil Pressure Switch by Patrick Brinson

Had codes P2646/P2647 and Check Engine Light on. Honda Accord 4dr LX 2005 4 cylinder. The car has misfires and loss of power from 2500 rpm. Replaced the oil pressure sensor and after driving 20-40 miles the code went away and the check engine light went out. The car doesn't stop anymore. If you search on YouTube you can find the exact location of the part for most makes/models and replace it yourself. The exchange takes no more than 10 minutes. Don't forget to check the oil level afterwards. When changing, part of the oil is drained.
