BruceY Posted November 26, 2007 Share Posted November 26, 2007 Check Engine light came on a while back, blink code told me O2 sensor OR purge control valve. replaced O2 sensor and installed a 33 ohht went ohm 5 watt resister in place of, light went out. for short time. Now back on and blink code has me puzzled. It goes as shown 3 long 3 fast = 33 3 long 4 fast = 34 3 long 5 fast = 35 then it repeats this sequence over and over WAZ UP?

Gloyale Posted December 10, 2007 Share Posted December 10, 2007 Firstly, you need an O2 sensor. The 33 ohm resistor is a fix for the EGR and purge solenoids, not the O2 sensor. a generic bosch single wire o2 sensor is all that's needed and they are only $20. What was the Original code? It could not be O2 OR Purge solenoid. It's one or the other. So one by one 32=o2 sensor 33= speed sensor 34= EGR solenoid 35= Purge solenoid Hook the o2 sensor back up, and then come back with the codes Quote Link to comment Share on other sites More sharing options...
heartless Posted December 10, 2007 Share Posted December 10, 2007 might I suggest this link: http://www.ultimatesubaru.org/forum/showthread.php?t=49918 Found this in the USRM - link at the upper right... Quote Link to comment Share on other sites More sharing options...
BruceY Posted December 10, 2007 Author Share Posted December 10, 2007 oRIGINAL CODE(S) were for O2 and purge control valve. see http://www.ultimatesubaru.org/forum/showthread.php?t=61840&page=3 Could have it gone bad within 2-3 years, the O2 sensor? I will get another one if you think so. I did the resister trick on the purge control valve when it gave me a 35 code. Stopped the "check engine" light for a short while, maybe something else went bad. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted December 10, 2007 Share Posted December 10, 2007 Well, I misinterpreted you're fisrt post. I thought you had the resistor in place of the o2. If you're not getting an O2 code now I wouldn't replace it. Have you tested the resistancve of hte resistors you used? maybe they blew? Anyhow code 33 is speed sensor. I'd clear the codes(hook up both green and white connectors, start engine, run for 45 seconds at over 2000 rpm, till the CEL blinks. You might have to even drive it forward then back a moment. Shut off and disconnect both connectors) Then see what you are still getting. Quote Link to comment Share on other sites More sharing options...
BruceY Posted January 18, 2008 Author Share Posted January 18, 2008 Just noticed the nitwit in me listed my Subaru as a 90. IT'S A 1992 LOYALE DID 2k rpm thing and blinking did NOT stop. Same sequence Quote Link to comment Share on other sites More sharing options...
Gloyale Posted January 19, 2008 Share Posted January 19, 2008 Turn the key on, and test for voltage at the connectors for each solenoid. For both, the Black w/White stripe wire should have 12v when the key is on. if there is no voltage there, test at the body side of the main engine harnes plug(large round connector behind the battery) Note that on the body side of the connector, the wire is Red w/Blue stripe. Just a thought since 12v for both are on the same wire, it could be an issue with that wire. Quote Link to comment Share on other sites More sharing options...
