Subaru OBD / OBD2 Codes

Table of Contents

NOTE: 96 & later are OBD2 systems and require a scanner. For an OBD2 code list, please see our Subaru code list or the generic code list.

Retrieving Trouble Codes

  • There are self-diagnositic connectors on all models, when connected with the key ON (engine off), flash trouble codes on the LED light of the oxygen moniter of the ECU.
  • The connectors are under the steering wheel, to the left of the module on most models.
  • On carberated and SPFI injected 89 models,the test connectors are located on the engine side/driver’s side of the firewall.
  • Imprenza models have the ECU and test connectors located behind the right side of the dash, instead of the left.
  • On SVX models the connectors are located behind the driver’s side kick panel.

Test Modes

  • With neither test connector connected and the key ON(not running), the codes will display codes related to starting and driving.
  • With only the “Read Memory” connector connected, historic codes will be displayed.
  • With only the “Test Mode” connector connected, a technician can perform dynamic tests.
  • The last mode is for clearing codes.(See Clearing Codes)

Reading Subaru Trouble Codes

  • The codes are displayed as pulses of the LED mounted on the module.
  • Long pulses (1.2 seconds) indicate tens and the short pulses (.2 seconds) indicate ones.
  • Pulses are seperated by .3 second puses and codes are seperated by 1.8 second pauses.
  • NOTE:on 89 MPFI models, the Oxygen Moniter light and ECU are mounted under the rear package shelf and are only accessible from the trunk.
  • On some later models the Check engine lamp and O2 monitor lamp flash the code(s) corresponding to the faulty part.
  • The long segment (1.2 sec on) indicates a “ten”, and the short segment (0.2 sec on) signifies a “one”.
  • 90 models – Trouble codes on the Justy are viewed on the Oxygen Moniter light, all other models the codes can be viewed on either the Oxygen Moniter light or the MIL (check engine light).
  • 95 Imprenza and Legacy models have OBD2 systems and require a scanner, but some basic codes can be retreived using the flashing MIL method.

Clearing Codes

Codes will only clear when the faulty system or circuit has been repaired. After making the repairs, codes can be cleared by connecting 2 pairs of connectors, the “Self-diagnostic” connectors and the “Read Memory” connectors that are usually to the right of the diagnostic connectors.

  • Start with a warmed up engine
  • Turn off the engine
  • Connect both pairs of connectors
  • Fianlly start the engine
  • This should clear the codes.

  1. Hello Michael and Beverly. Yes there is a way to induce codes on a Subaru. Under the driver kick panel, there should be two green connectors next to each other that when you connect them, it puts the vehicle into check mode. With this year and make, there is a crankshaft position sensor on top of the crankshaft that sometimes gets bumped or unplugged if someone has been working in that area. First, make sure your timing marks are all aligned with the number one cylinder at top dead center. Have you tried rotating the crank 4 times then re-checking the timing? Also, as another resort, I’ve taken out starters to make sure it is not binding with the flywheel.

  3. Is there any way to get codes to pop up my 2002 Forrester was running u
    I changed oil and plugs then somebody who thought they knew what they was doing and they put a ratchet on my crank pully and turned it clockwise and now car turns over but will not start I took off timing cover and put every mark from intake all the way across and put belt on put it back together and it turns over but it has slow crank and won’t start please help

  4. I just bought a 2006 baja turbo 2.5 litre. These are the error codes that have come up, P2138 x Throttle/Pedal position sensor/switch “D/E” voltage correlation, P0345 – Camshaft Position Sensor “A” Circuit Bank 2, and P0340 – Position Sensor “A” Circuit Bank1, or single sensor.
    My question is, is it dangerous to drive with these error codes?

  7. Hi there and thanks for the helpful info.
    I’ve got a 1999 Legacy Lancaster, 2.5 litre 4WD non turbo. I think it’s a kind of Japanese version of the Outback.
    It’s got weird electronic problems, including not charging ( with no battery warning light displayed) and a bad miss when accelerating at all below 2500 rpm.
    Check Engine Light flashes error codes 22 (knock sensor) and 85. Any idea what 85 is?
    The OBD won’t talk to my reader, as is the case with my other Lancaster.

  11. I have a Japanese import 1999 Forester SF 5 2.0 in the Caribbean. I have a hesitation in the transmission, that when I put into Drive, there will be a pause for a few minutes then the car will move. Which is the correct OBD to diagnose that problem or can you give a code for that .

  17. P0420 code on a 2002 Subaru Forester. Recently had major tune up. Did valve cover gaskets, plugs, wires, ignition coil pack & knock sensor. Cleared codes P0303, P0304 & P0325. The next day code P0420 popped up. What’s the most common scenario in your estimation?? O2 sensors?? Air Intake system?? Cat??

    • For your Subie, DTC P2097 is Post Catalyst Fuel Trim System Too Rich Bank 1. The post-catalytic converter oxygen sensor is reading fuel system too rich, which means either the cat is no longer processing properly or you have an exhaust leak. I’d start with checking for exhaust leaks. Still, for the age of your vehicle, old oxygen sensors can get lazy or stuck, which the ECM interprets as a fault, so it could be a lazy oxygen sensor. The catalytic converter would be the last resort but, because of the age of the vehicle, it may be at the end of its life.
