    Do you only get fuel trims for 1&3? Without knowing how your obd reader displays info, I have no insights, but a trim of -100% definitely seems to indicate something wonky… maybe someone who knows a little more about how to interpret that can help. I’ve become spoiled by having an Accessport now.

    I can se Fuel trims 1, 12 and 3. Not sure the differences though. i only can see the FTRM3 with the Freeze Data when the code trips, I cannot see it in live drive like I can everything else. Watching the sensor readings everything looks fine while driving. The code has not tripped during the time I have had the scanner attached and driving.

    Going to smoke check the car and see I can locate leaks before throwing parts at it.

    Any idea how old the sensor is? Genuine Denso part or maybe not?

     

    I believe it is the original. Looks like a factory original. Popped the code again, coincidentally in the exact same spot on my commute. This time only one day later and about 70 miles.

    I took pictures of the freeze data, but the O211 didn't show on it but these did:

    ST FTRM1: 0.7

    LT FTRM1: 4.6

    ST FTRM3: -100.6

    LT FTRM3: -100.6

    I've never seen FTRM3 before

  3. So, I have been getting the P0420 code for the last week or so on my 2007 Legacy Limited. Issues started with the P0171 code, for that I straightened the intake duct that was cocked and cleaned the MAF. That seemed to take care of that. Then the P0420 came up on the way home from work. Checked over the car with nothing obvious noted.

    I cleared the code and decided to see if it returned, set up and my ran my Actron live drive on the way to work and for the next few days. After several days I took the scanner off the car.  Sure enough the code returned the following day. This was about 250-300 miles later, in the exact same spot on my commute. I viewed the freeze data and found the o211 mA at around 250.00. Once again, I cleared the code set up and my ran my Actron live drive on the way to work and for the next few days.

    The o211 mA is jumping around 0 to 250.00, when at idle or below around 50mph. On the open interstate 60 to 75 mph the o211 mA is 240 to 258. When slowing from 70 the reading drops to 0 to 5, then starts jumping up and down again. Fuel Trims seem to be normal as does other indications. Once again the code returned about  two days and 170 miles later.

    I’ve done a bunch of searching on this issue, but most talk about voltages, which on my car seem to be normal. I could not find much on what the milliamps are supposed to be, except one article that leads me to believe it should be in the 1-5 mA range.

    I’m tempted to replace the front O2/AF sensor, but I am wondering if the high milliamps and jumping around is the sensor or something else. Car runs fine and 30 plus mpg.

    Here is a link to the video of the live drive showing the sensor indications:

    Any ideas?

  4. Been lurking around the last few weeks.

    2007 Limited, 155k miles, wife and I inherited it from her parent’s (both passed in Oct, 11 days apart).

    We decided this will be my daily commuter, replacing my BMW e30 (decided to start restoration after 33 years and 234K). Been driving a Nissan Frontier 4x4, the last two years. (too much gas!).

    This is our 5th Subaru: 84 GL wagon, 2011 Forester, 2018 Forester, 2021 Ascent (Wife’s current ride).

    Not a bad car, kind of like it. She handles nice and has some get up and go. I’m not a truck/SUV guy, I like my performance cars. I was thinking of getting a new Legacy or Impreza before this because I need something for winter mountain driving.

    A few things I have noted:

    • ·       Averaged 31.5 mpg (according to the computer) on the 7-hour drive from eastern PA, on ethanol laced fuel. Is that normal? I was expecting 27 mpg.

    • ·       CEL came on during the trip P0171, lost cruise control (Annoying!), pulled over and reset to get cc back. I’ve tried a few things to correct this but have not got the car registered yet to drive it full time yet.

    • ·       No Bluetooth, Grr. Ordered a Bluetooth Aux adapter with mic for now. I’ve read about the issues with swapping out the radio with the Dual Zone HVAC. Another annoying issue.

    • ·       Speedometer is almost 6 mph slower than GPS at 70-75mph. Most error I’ve seen on cars are 3mph on my BMWs. Been reading up on that too.

    • ·       Timing belt is due in 2 years, less than 30k since it was changed. This will be my first Subaru timing belt change. My e30 takes about 4 hours to do.

    • ·       Going to keep an eye on the head gaskets, I told my father in-law to have them looked at, but never asked if he had.

    Any other items I should look over? I’m a Certified Aircraft Mechanic, Retired USAF Flight Engineer and been a gearhead my whole adult life. I don’t take my cars to the shop much, I prefer to take care of things myself.
