Sensors in exhaustpipes
Hi,
I have a question about the sensors in the exhaust pipes. I have a EG33 engine from a 1991 JDM SVX. In the exhaust pipe are 2 sensors ( 1 left and 1 right), these are the "lambda" sensors or o2 sensors. 20 cm further there are another 2 sensors in a sort of small muffler left and right. What are these sensors and what are they for?
Thanks,
Peter
