Has any one had any experiance with the following trouble codes,

and if so can you offer guidance on the trouble-shooting?

 

Vehicle is a 95 Impreza 2.2 L

 

P0304 Camshaft Position Sensor Circuit Malfunction

 

P0400 Exhaust Gas Recirculation Flow Malfunction

 

P0106 Manifold Absolute Pressure/Barometric Pressure

Circuit Range/Performance Problem

 

I only have the Chilton's which is not a lot of help in cases like this.

 

Any help appreciated, Bill

I had the P0400 Exhaust Gas Recirculation Flow Malfunction ECL.

The shop cleaned the tubing and the EGR valve and so far, 4 months later, no ECL.

 

Never had any other ones.

1) camshaft position sensor. It's on the front left side (driver) of the engine. Just left of the oil dip stick if I remember well. Check the connection and if good replace the sensor. A five min one bolt thing, 17$ at 1stSubaruparts.

2) As for P0106, I think - but not sure - that the pressure sensor is on the front of the right (passenger) strut tower. One possibility would be that the vaccumm hose connected to it is broken or disconnected. Did you replace the air filter lately?

That's the limit of what I can contribute. Good luck!

With that many codes in the computer, I would clear the codes and then see if they come back on. If one of them come back up then I would go after them. It is not usually for a bogus code to come up now and then.
