Question about 1995 Subaru Legacy
P0441 Evaporative Emission Control System Incorrect Purge Flow
This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses.
The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere.
A vacuum switch is used to detect when flow exists. If the ECM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
Symptoms Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Causes A code OBDII Trouble Code
P0441 could mean one or more of the following has happened:
If engine seems to want to stall at low idol speed (rpm), could be due to a vacuum air leak near/around or on the air intake manifold, or connecting vacuum hoses and/or lines.
*Could also be the vacuum line leading to charcoal canister.
This will cause lower vacuum suction of air intake and loss of compression in motor, will cause unstable idle.
Also Canister Purge relies on intake vacuum to syphon fuel vapors into the engine.
A vacuum air leak on intake manifold / connecting components / hoses / lines will cause
-low intake air preassur
-low air compression in motor
-low vacuum suction will reduce EVAP vapor flow
-trigger MIL Light EVAP Inccorect Purge Flow
No MIL light for vacuum leak.

Code p 0441 refers to evaporative emission (EVAP) system --incorrect flow detected ==== causes --- hose connection/s--- intake leak---EVAP canister purge valve replace the purge valve

Check The Vehicle Speed Sensors.
The Legacy has 2 Vehicle Speed Sensors (VSS): VSS1 is located inside of the transaxle; VSS2 is located in the combination meter assembly.

Yes as long as the Motors are the same. You might need to have the computer out of doner car. Doors are suppose to fit 96 to 99.

It's in 'safe mode'. Fault 66 is a nightmare! Usually caused by the sensors not talking to each other properly or 'disagreeing' with each other. Check all the sensors are pluged in & have good connections. A dirty connection can cause this code to appear. Disconnect the battery & touch the + & - leads together to discharge the system & reset the computer & fault codes

It has to be jerked just right for them to lock. Foreign cars are real touch when you **** them. American cars pretty much only lock up when you stop quickly and your whole body puts pressure on the belt.
