Ravenwoods Posted November 4, 2017 Share Posted November 4, 2017 My daughter has a1995 Impreza with the EJ18 Engine and the check engine light came on. I don’t see a place to plug in a code reader. Where is it? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted November 4, 2017 Share Posted November 4, 2017 deosn't have one. Subaru didn't start obd-ii until 96. You need to find the pair of black connectors under the dash and plug those toghether, and then either the CEL or a LED in the ECU will flash codes in 10's and 1's (3 long pulse, 2 short = code 32) Quote Link to comment Share on other sites More sharing options...
Ravenwoods Posted November 4, 2017 Author Share Posted November 4, 2017 Thanks. So there are plugs under the dash on the driver’s side that need connecting? Where is the ECU? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 5, 2017 Share Posted November 5, 2017 95 Legacy's have OBD-II, at least an early implementation of it. Not sure on the Impreza - it may not. GD Quote Link to comment Share on other sites More sharing options...
Ravenwoods Posted November 5, 2017 Author Share Posted November 5, 2017 Check engine light has gone off. Does the 95 Impreza store codes for a while? Quote Link to comment Share on other sites More sharing options...
wtdash Posted November 5, 2017 Share Posted November 5, 2017 yes...codes should be stored w/the KEY ON, Engine OFF, plug in the connectors and watch for the CEL light to blink the codes. ECU is probably under pass. footwell. '95 w/the 4EAT (Auto) and EJ22 had OBD2 on Impreza and Legacy; not on the EJ18 in the Impreza. Not sure about the EJ22 and 5-speed on the Legacy....AFAIK.

Ravenwoods Posted November 6, 2017 Author Share Posted November 6, 2017 I just pulled the Impreza into our warm garage. I saw a big yellow plug but no corresponding plug. Then I saw two green plugs and plugged them together. No blinking lights but the radiator fan turned on and off. Quote Link to comment Share on other sites More sharing options...

I found green ones. Also one yellow one that doesn’t have a mate. No blinking ABS light. But the radiator fan turns on and off. Could the green ones be the correct plugs?

wtdash Posted November 6, 2017 Share Posted November 6, 2017 (edited) Green for diagnostics - cycles the fans and sensors on/off. Look it up in the FSM/factory service manual: http://jdmfsm.info/Auto/Japan/Subaru/ If you do NOT have the OBD2 connector, I'm 99% sure those black connectors are there - taped/tucked to another harness most likely. : The yellow connector is the Subaru SSM for Subaru Tech/Mechs to use. You could build a cable and buy/download software (not Subaru-specific) and read info, but it's not the most user-friendly option.

Ravenwoods Posted November 6, 2017 Author Share Posted November 6, 2017 I found the black connectors and it flashed five long and six short. So 56. What’s that mean for a 95 Impreza? Quote Link to comment Share on other sites More sharing options...

wtdash Posted November 6, 2017 Share Posted November 6, 2017 (edited) My 95 legacy MT has it Cool.....that'd mean to me that all the 1995+ 2.2's were OBD2 (you can't get an '95 Impreza w/a 2.2 and 5-speed). Per Cars101.com: As did all 1995 Imprezas...... came with either the 1.8L engine and manual trans, or the 2.2L engine and automatic transmission. Manual transmission available with 1.8L engines. The only 1.8L with auto. trans was on the base Impreza modelAutomatic transmission available only with the 2.2 L engines. There were no 2.2L with manual. trans.

SUBARU3 Posted November 6, 2017 Share Posted November 6, 2017 My 95 Impreza 2.2 auto/AWD is OBD2 and has a plug. Quote Link to comment Share on other sites More sharing options...
Ravenwoods Posted November 7, 2017 Author Share Posted November 7, 2017 The Check Engine Light has been off most of the time and didn’t come on today. I got some carburetor cleaner and cleaned the EGR up this evening. Hopefully that will extend its life for a while. I might as well preemptively clean the EGR on our 98 Forester now.
