When your car is not running correctly, it is important to diagnose the problem correctly. The Honda code P0523 is a specific code that may be causing your engine to run with poor performance. It is important to identify the cause of this code in order to diagnose the problem correctly. The code P0523 is triggered when the rocker arm oil pressure sensor A output voltage is 4.79 volts or more for at least two seconds with the engine speed a maximum of 4,000 rpm and engine coolant a minimum of 140 ºF (60 ºC). This code can be caused by a variety of factors, including poor connections or loose terminals at rocker arm oil pressure sensor A, an open circuit between the PCM and rocker arm oil pressure sensor A, a faulty rocker arm oil pressure sensor A, PCM needing an update with the latest software, or a faulty PCM.
