But can a sensor fail to short ? I was thinking about have a good look at the fuse box first (I have seen that problem before), then failing that disconnect all the sensors and then see if there is a short. hopefully there wont be and then ill connect each one in turn - What do you think of that approach?
If it's possible to do yes. Given its engine fuse 13 blowing its likely an O
2 sensor heater that's failed possibly as you suggest to a short within, although wiring to same is a possibility.
Mad !!! Its a wiered one . I can find the part with the same reference and the right connector, NTK but the cable length is about 12 cm and the one off the Mog is about 60cm. I cannot find the exact one anywhere . I will keep digging . I have a feeling it may not be standard hence why Mog charge £285 per sensor. Strange!!!
Can confirm the upstream O
2 sensors are six wire and downstream four wire, with two of those for the heater in each case. The voltages measured by the sensor's drop to fractions of a volt with a warm engine so would advise against extending cables to suit installation due to any inadvertant resistance creeping in to the sensor circuit, in turn affecting fuel mixture when system goes into closed loop.
Not convinced the items are standard 3.7 Mustang either given the custom Morgan tubular manifold's and exhaust system. Add to this there were changes to Mustang engine spec after 2013, which I believe involved a change of O
2 sensors. FWIW the Roadster seems to adopt the earlier spec. and this is certainly true for the air filter element.
