Every day is a #DiagnosticDay. . . #REPOST jakescarcare Nissan Versa came in with a crank no start. Had a code P0335 (crankshaft sensor circuit malfunction). We wanted to make sure that sensors signals waveforms were correct. Oscilloscope is the best way to see what the sensor is doing in real time. Everything checked out. We ended up find the fuel pump being faulty and extended cranking by the customer caused the crank sensor code to appear. This is an actual diagnostic approach as opposed to just shooting the parts cannon at it until it runs. #mechanic #technician #diag #fixme #snapon
