Need to correct one thing as for the video above. It occurs there are two types of catalytic converters on both z19dt and z19dth, depending on if there is a DPF or not. If there isn’t, there is a lambda sensor fitted at the top. If there, however, is no DPF, there is a temperature sensor at the bottom on the left on both z19dt and dth. The pictures below show z19dth catalytic converters from a Zafira with DPF on left and with no DPF on the right.
