On a 1993 Subaru Impreza, the oxygen sensor is typically located in the exhaust system, either in the exhaust manifold or just after the catalytic converter. For most models, you'll find it on the exhaust pipe leading from the engine. Depending on the specific engine type, there may be one or two sensors (upstream and downstream). Always refer to the vehicle's service manual for precise location details.
yes
Oxygen sensor
One is in the exhaust manifold on the passenger side, the other is in the exhaust after the dowpipe.
A MAF sensor for a Subaru Impreza can cost anywhere from $70 - $150 depending on the type of Impreza you have.
Screwed into the exhaust pipe.
no the primary one is the one closest to the engine
The speed sensor on a 98 Impreza is on the gear box. it is on the driver's side under the bulkhead.
It's threaded into the front of your exhaust manifold.
It's a code for the oxygen sensor.
Back side of the engine....mounted in the exhaust manifold.
I have had the same problem with my '93 Impreza. The button on the automatic shifter will not depress to take it out of park. There is an override option in the owner's manual but I think the real problem is the brake light sensor. Ocassionaly, when I can actually get it out of park, you can hear a clicking noise when the brake petal is pressed, this is the shifter-lock releasing. It must be the sensor for the brake petal going bad.
No , it is not an interference engine
