ECM low output signal Voltage
2009 R56 non turbo....starts fine ...power drops off bad after 5-10 seconds of running..last code was a Knock sensor low voltage. Output of terminal 33 at computer is only 1.6 volt....checked output of some other terminals was only 3.6 volt but I can get a 5 volt signal on the cam sensors...ECM gong down but still enough to run the vehicle?????
