Hi , I have a subaru impreza 2009 with a po137 code I replaced ox 2 sensor banck 1 , reset the code but still coming back...any suggestion?

SOURCE: 98 subaru impreza knock sensor

at the top of the block under the plenum runners.
please leave feedback
cheers

SOURCE: PO137, PO 138 codes

well on my car these are reffering to the sensors in the exhaust, the upstream sensor(before the cat) and the downstream sensor(after the cat) the downstream sensor can act up if it is lazy or sluggish, or due to a bad catalytic converter or a clogged one. however there are sensors on the exhaust manifold which are determined by driver side or passenger,my opinion is to get a scanner for about $100 to $150 and you can figure out many of these codes yourself.

Sounds like warped fly wheel.

i had this problem with mine if your cable spins wen the car is moving its not the gear box end or the cable its the speed sensor in the speedo its self its very easy to fix you have to strip the speedo out of the case the sensor is only small and on the under side of the speedo the sensor is about 50 mm long and 10 mm wide change that and it should be ok
oh remember to reset your ecu

If there is one - In trunk - directly behind the gas filler door - behind trunkliner (carpet)
The cable should not have any problems... use a partner to hold the door release and try and pry it open with your fingers.
The spring popper may be bad.
Try this if you dont have an assistant :D

I had this problem with my STI -- easy to fix by bending the little metal on the inside of the fuel door that provides the spring action to open the door. 5 second fix
