Hi guys, really needed your help. Does the above car has the following:

1) Knock Sensor?
2) 2 Oxygen Sensors?

Please let me know.

Thanks!!

 

1) Yes
2) Yes

 

Hehehe...yep an EF9 has these two sensors.

 

Thanks! Can you tell me the exact location of the 2 oxygen sensors and the knock sensor?

By the way, have you ever tried using only 1 O2 sensor?

All questions that I have asked, is because my car is short of alot of things, need to rebuild the whole thing again..

Please reply asap! Thanks.

 

For the O2's you should have one up top on the exuast mani. and one at the bottom. The knock sensor is located on the bakc of the block by the Oil filter.

 

Actually the two o2 sensors go on the exhaust manifold, it's like where cylinders 4,2 meet and 3,1 meet.
