    To check for codes on this subaru, you need to plug in the two black connectors next to the steering column, the two green connectors are for an overall system check, plugging them in tells the car to do a function check of the sensors, it cycles the fan, and a number of other sensors to shop operation. To clear the fault codes, disconnect negative and positive and touch the two leads together,

Check the knock sensor.

The light comes on when you climb a hill, accelerate quickly or do anything that advances the timing a lot and the knock sensor doesn't hear the knocks (pinging). The engine timing is not retarded, so you get a misfire.

The computer turns off the CEL if it sees the car start and run with no misfire of this nature 4 times in a row.

SOURCE: Engine check light comes on

Have you tried disconnecting the battery for half an hour to reset the computer? If that doesn't work I think the Vacuum Pressure Sensor is in the black box with all the vacuum hoses going to it beside the air filter housing. Not sure tho, subaru will tell you where it is & how to test it if you ring them & ask for the workshop.

There's a pair of connectors, green, under dashboard on left. They should be left unplugged. When they are plugged together, they cause the lights and fans to cycle on and off for diagnostics.

Your model and year has OBDII. I would not suggest shorting any wires. It will not flash codes. Most Auto parts stores will test it for free. Good luck and have a great day.

Headlight low beam


Test to see if you have voltage at the bulb connector in low beam position. I'd almost bet that if there is no voltage there for the low beams that you have a bad high/low switch.

Override remote


I have a similar type of problem. After charging the battery and re-setting the computer, the front and rear lights that would be on in the drving light mode, now are somehow connected to a flasher unit and continue to flash even when the key is off. The only way I've found to stop the lights flashing is to pull the green fuse in the computer box. Looks forward to learning how to fix.

That depends on the type of fault!

The car will have to be connected to a diagnostics system to find out the fault.
