Well at last the waveform is here I hope, right here goes, The vehicle is a VW Lupo 1.6 GTi AVY engine fault code is P0160 = fuel trim bank 1 malfunction, the trace is the signal wire on both oxy sensors, the problem is the signal on the front sensor the voltages and earth seem to be fine at the block connector to sensor this trace shown is what is happenning now after cleaning earths and connections on ECU, before this the trace used to spike randomly up to 0.8volts. Since I've done the connections, engine light has'nt come back on?
I'm still fairly new to picoscope so I dont pretend to be an expert by any mean's, just wondering what your thought's are?
