I have a 2005 2.0T GT sedan with an O2 sensor throwing a P0030.
Subie is so darn expensive I thought I'd try an after market.
The problem is many of the aftermarket guys are showing two different connectors.
Some show a 4 pin male connector on the sensor cable others show a female.
I contacted many of the suppliers and provided my VIN number.
4 of them came back with the same answer.
"Your model has two different sensors, you need to remove it and check before placing an order"
Does anyone know what's really going on?
Is there some way of telling what to order that doesn't involve pulling the old one out?
I was hoping to pull the puppy out once.
