    Hi I have the same issue, i posted a seperate question, did you find a resolve?

    It is one of two places, the differential pressure sensor is o/s/f bulkhead.

    Air pressor sensor solenoid is in the solenoid/ vac box o/s/f inner wing (rhd) I think it is the second solenoid I am trying to clarify this as I do not know which is relevant to TC45. just waitin on some more info...

1992 Subaru legacy wagon will not shift up from first gear. it is an AT.


run the fault but all you describe is operated from the VSS sensor ( vehicle speed sensor)
it tells the cruise control the vehicle speed , tells the TCM the vehicle speed so that ratios can be changed, activates the speedo,and will report with a check engine light to report a transmission problem
run the fault codes first

Codes related issues have to be diagnosed & find
a problem & fix it

There is no getting rid of dash lights,MIL Lamps,

Expect to hear your head gasket needs replacing, at a minimum. White smoke means it's burning coolant. How much it will cost I can only guess, but usually a head gasket repair- a few hundred dollars-it's pretty time consuming and labor intensive, especially with all the turbo stuff that could be in the way. Good luck.

Hi, I have a '95 2L Legacy Boxer 2 stage twin Turbo. When i'm driving and the engines reving at ot just above 2000 rpm I'm getting a dip in power for a moment before it picks up again. I haven't noticed...


the 1st thing that needs to be done here is to find what fault code is turning on the check engine light, this information is absolutely crucial to making an accurate diagnosis of this problem, guessing is not an option as each part that could cause this is very hard to replace and very expensive, so get the the engine control system tested, this is what is called OBD 1 electronic engine control and requires a Subaru scanner to read code.

95 Subaru legacy wagon manual transmission fluid


The dipstick has a black plastic handle in the shape of ring of about 1 inch in diameter. It is located on the left side of the engine (looking from front) behind the spark plugs. Best visible from the passenger side fender location (start looking from the left part of the transmission , the black handle clearly stands out on the white metal).

Fault code 45- how do i repair it?


The code 45 in a later model is for the AWD control module causing harsh shifts. On a 2000 model the warranty per recall is 8 years and 100,000 miles. For your model you can try calling a dealer about recalls.
