Abstract
An engine oil filler cap for monitoring an internal combustion engine comprises: a processor; and a sensor module comprising a pressure sensor configured to sense crankcase pressure of the internal combustion engine and to output data representative of the sensed crankcase pressure to the processor. The engine oil filler cap is configured to provide a housing for the processor. The processor is configured to determine a value representative of the firing frequency of the internal combustion engine based on the output data.
