EGR code
ocei77 replied to sub96's topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX
There are other tests to be made. Google Subaru DTC codes and check yours. Make sure the small metal line from the EGR to the solenoid valve is clear also. You can test the solenoid by connecting the green plugs under the dash and turning switch on. Listen for the clicking to confirm operation. Don't forget to unplug afterwards. In the future please start with more specifics.ie Engine, mileage. O. -
jack it up and remove the heat shield bolts (you'll probably have to cut them off). This way you can raise the shield enough to get an open end onto the bung and another on the sensor itself. If you don't a good 19mm open end, a small pipe wrench will work also. Spray with PB and try to tighten a bit to break the tension. Then unloosen. O.

You have the marks correct. Is the tooth count on the belt correct? 44 from crank mark to passenger cam and 40.5 to driver cam. If this is correct then something is unplugged. Check crank , cam sensors and IAC hose to intake. O.

Use emery boards to clean the contacts. Unfortunately I left my diagram of pins for the harness where I won't get back to for a few days. In either case looking at the back of the connector #1 is Br, 2 is LG, 3 is LR and 4 is YL. Check resistance and see if one/more are much higher than the others. This may help you to narrow down if only one or two pulsing low. O.

Large screwdriver from behind. Can even tap with a piece of wood against the sprocket, rotating to even the movement. O.

The chips on the pulleys are benign, If they are not cracked I wouldn't replace. If you want to, a junk yard would be your best option. I've never had to use a puller to get them off. You are replacing the idlers, right? Remove oil pump and tighten screws on back if loose. Don't tighten the valve covers until after you have tightened your sprockets. A 1" open end will fit the flats on the cams to hold them. Careful of torque on cam bolts, the specs are very light. I know where the plug goes, but not enough knowledge to tell you where it goes w/o looking at an engine. Am sure someone will chime in here. Continue to take your time and all will be well. O.
