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
It's threaded into the front of your exhaust manifold.
The speed sensor on a 98 Impreza is on the gear box. it is on the driver's side under the bulkhead.
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.
It's a code for the oxygen sensor.
Back side of the engine....mounted in the exhaust manifold.
In the 1994 Subaru Impreza WRX, the oxygen sensor is typically located in the exhaust manifold or just downstream from it in the exhaust pipe. The sensor connects to the engine block through a threaded fitting in the exhaust system. Wiring harness connectors link the sensor to the vehicle's engine management system for monitoring exhaust gases and adjusting the air-fuel mixture. Always refer to the vehicle's service manual for precise locations and specifications.
