Honda legend O2 Sensor and ECU location

[bdang007]

Hey guys,
anyone know where those are located? I believe if the O2 sensor is broken there will be excessive fuel consumption. I think this may be why my legend is eating up so much fuel. Anyone know where this is so i can check it/get it checked. The ECU part is to satisfy my curiosity :)

Thanks!

depends what ledgend you have

on the 2.7l the O2 sensors are on the exhaust manifolds. the ECU is under the glove box behind the carpet. look for the flashing red LED


on the 3.2l the O2 are again on the exhaust manifolds, but you have to bridge the SCS connector to get the codes from the ecu. the ecu is under the glove box behind the carpet as well..

would the 3.5L version be similar to that of the 3.2L? I have the 3.5L 98 model.
