im also need the answer , i got a decat pipe on mine and my sensor is still screwed into it and plugged in but if your decat hasn't got the threded hole for the sensor then i would either drill it and tap and die it or keep it plugged in but tie it up out of the way but if the car starts playing up then you will have to fit it somehow.
A MAF sensor for a Subaru Impreza can cost anywhere from $70 - $150 depending on the type of Impreza you have.
One is in the exhaust manifold on the passenger side, the other is in the exhaust after the dowpipe.
The fuel temperature sensor is located inside of the tank in the Subaru Impreza. This is the case for the cars that were made in the 1990's, at least.
built in with MAF sensor
The function of the oxygen sensor in a Subaru or any other car is to measure the amount of oxygen that is mixed with exhaust gases.
as far as i am aware it is on the maf sensor, still looking into it
When a Subaru has a faulty O2 sensor the fuel management is out of whack.
At the rear end of the transmission
on the gear box down the drivers side below the bulkhead
Upstream o2 (oxygen) sensor. Should be directly behind your radiator, down low. It's the one in your exhaust manifold.
Under the intake arch on the left side of the engine.
The code 32 for a Subaru vehicle is for the coolant sensor or the oxygen circuit.
You cannot bypass this sensor.
Directly behind the alternator on the main block, facing downwards into the engine
can anyone help me please Its the sensor directly under the intercooler remove the intercooler and a couple of airpipes and you will get at it easiar.
Absolutely. Not just on Subaru but every car built that has an oxygen sensor. And they all do.
Remove the intercooler first. The knock sensor is located under its loation. But you will have to remove some breather pipes to get to it. You will need a long ratchet.
Probably referring to a heated oxygen sensor.
Cam sensor and/or crank sensor.
the speed sensor is in back of speedo clock change the clocks if faulty as it puts your car in safe mode and wont go past 3000 revs
You can find the knock sensor on the top side of the engine under the intake manifold. It is easiest to find from the driver's side and is at the back of the engine block.
I believe its inside the fuel tank, on top of the fuel pump. I'm searching for the same thing for my 95 impreza, and they are saying its somewhere inside the tank. There is an opening in the back of the rear seat on the tank side where you can access the pump and the sensor.
The speed sensor on a 98 Impreza is on the gear box. it is on the driver's side under the bulkhead.
Oxygen sensor on 1990 Subaru Legacy is under car, just behind engine where exhaust manifolds join but before catalytic converter. Wires run up right side of bellhousing and connect into wiring harness.
The oxygen sensor measures the amount of oxygen in the exhaust gases. Theoretically, if the fuel mix is perfect, then there should be no oxygen in the burned gas ... if it detects O2 it assumes that there wasn't enough fuel ... and adds more.
