i took my cabriolet megane 55 reg to the dealers, and the diagnotic indicated upstream, downstream sensor, when i asked my local mechanic he said it 's impossible to tell apart thing as the lamba sensor is this true? what is the map middle?
Answers: when they are referring to upstream sensor they mean o2(oxygen) sensor specifically mounted in front of the catalytic converter so the downstream sensor is an o2 mounted at the rear the converter
o2 sensor, oxygen sensor, lamba sensor are all impossible to tell apart thing
map sensor= several absolute pressure sensor, it's a fancy christen for engine vacuum (at a point below the throttle plates)
