Man, this car is getting annoying. What does it mean when CEL & Traction lights are on solid, and cruise control flashes? I have checked the codes and I get P0037 as a result. It's still hunting a bit at lights, and almost stalls when stopping at times, but seems to be fine at power. *shrugs* don't want to spend more money on this thing, might be time to get rid of it maybe.
Hey Guys, sorry if this is in the wrong place or somebody has a similar post but I've got a number of check engine fault codes on my 2001 BH9 Legacy 250S EJ25 (always run on 95 petrol) they are P0390, P0365 and I did have a P0130 code which might've been before I replaced the O2 sensor post cat. The other 2 codes, which I believe both relate to the camshaft position sensor. It seems to be the case because when the car is at operating temp it loves to dip very low on idle sputtering and stuttering, loss of power and almost dying, etc. I ended up buying a new camshaft position sensor from supercheap and I've replaced it with the one that lives on the passenger side towards the front of the engine near the engine oil filler tube. But I've still got the same codes after resetting and I've tried a lot of other things like injector cleaner and I've cleaned the throttle body replaced air filter added (mbl8 oil additive I think?) oilange with filter every 10k km and all that jazz. It also has some type of tick along the whole rev range, to me it sounds like it's coming from the top end on the passenger side. Other than that the car runs mint when it feels like being normal but it guzzles fuel like crazy, pretty much almost 15-17 litres /100km around town. Sorry about the novel I just wrote but I'm out of ideas and I am a student so any help would be much appreciated!
How to Read Trouble Codes From the ECU On the gauge cluster, to the top left there are a few idiot lights which are not on under normal driving conditions. One of these lights reads 'check engine.' This light comes on when the ECU detects a fault in one of the many electronic components from which it receives signals and to which it transmits signals. If the ECU recognizes a problem while the car is on, the 'check engine' light will be constantly illuminated. If it has detected a problem in the past, but the problem which it detected no longer exists, the light will be out. However, the ECU will store a record of the faults it has detected in the past until they are cleared deliberately or unintentionally. To read any current or past faults, the 'check engine' light will flash in a sort of Morse code, which we can decipher. Underneath the steering column is a wide rectangular piece of plastic, the same color as the dash, which has a tray marked 'TRAY.' This large piece is held to the underside of the dash with a bunch of screws. Remove these screws and remove the plastic piece. Now there will be a bunch of wires for you to see. To the left of the steering column (at least in left hand drive cars) somewhere probably tucked away will be a bundle of wires with two pairs of electrical connectors which are disconnected. One is black and connects one wire to one wire, the other is green and roughly 'T' shaped, this one also connects one wire to one wire. With the car turned completely off, connect the black connector. Next, turn the ignition to 'ON' but do not start the car. The idiot lights in the dash will come on, and some may go out after a few moments. Watch the 'check engine' light and maybe have something you can write on to remember the codes. If there is a fault code in the ECU, the 'check engine' light will begin to flash in a particular manner. The codes range in number from 11 to 52, so we know that they all will be two digits. To signify the tens place of the number, the 'check engine' light will flash a long (1.2 seconds) flash. The single digit will be a short (.2 seconds) flash. Each flash within the same code will be separated by .3 seconds. Each error code will be separated by 1.8 seconds. Don't bother trying to time all these, just watch the light and you will begin to understand. Once the ECU has flashed all stored codes, it will loop through and repeat them. Now, for example, you see two long flashes followed by two short flashes. This means you have a code number 22. By looking at the following chart, we see that 22 is the code for the knock sensor. Once you have read and recorded all faults, turn the ignition off and disconnect the black connector. If you have done the above procedure, you will likely wonder what the green T-shaped connectors are for. These are for a more active code reading procedure called D-check mode in the Subaru manuals. Start with both connectors disconnected, start the engine, allow it to warm up, then turn it off. Next, connect the test mode connectors (green T-shape). Turn ignition to ON position without turning on engine. At this point if the check engine light does not come on, it is faulty and must be fixed before continuing. Depress accelerator pedal to floor, return to half throttle and hold for two seconds, then release. Start the engine. Now the light can blink in two different ways. If everything checks out so far, it will blink to indicate a number 01, 02, 03, 04, 05, 06, 07, or 08. If a problem is already detected, it will blink according to the chart below. Either way, your next step will be to drive the car with the test mode connectors connected. You must drive over 7 mph for at least one minute, and shift up to 4th gear if you have a manual tranny. Now, either you will discover your trouble codes, or you will have none. To erase trouble codes from the computer (without resorting to the infamous battery disconnect dance), repeat the above procedure exactly, but connect both the green and black connectors at the appropriate time.
