joejk1 Posted December 12, 2012 Share Posted December 12, 2012 mode 3 stored trouble codes,read the directions again and figured it out,duh Link to comment Share on other sites More sharing options...
joejk1 Posted December 12, 2012 Share Posted December 12, 2012 well it flashed 34 knock sensor,but i am having tranny trouble? Link to comment Share on other sites More sharing options...
nunya Posted December 21, 2012 Share Posted December 21, 2012 checked my codes today so I decidced to make a quick video as well for those may get a little confused what they are watching for first part is the mode selection part, I let it cycle 2 full times first just to see the 'full cycle' (1-2-3-4-5) on the 3rd cycle I switched to mode 3 and let it cycle my codes twice. Watching the flashes you will see I have a code 13 (coolant temp sensor), a code 21 (ignition signal), and a code 11 (crank angle/cam position sensor) Hope it helps someone a little 2 Link to comment Share on other sites More sharing options...
preith Posted March 23, 2013 Share Posted March 23, 2013 http://www.youtube.com/watch?v=wUL7SL9ORu4 I hope this helps! I wish I would have watched this first, my '95 WD21 behaved identically, took me a good 1/2 hour to figure it out. The instructions threw me off a bit because per them, only the VG30i behaves this way and has a toggle swtich, not a screw, and doesn't specify returning to normal position after the 3 flashes. Regardless the info was still invaluable, thanks to the OP! Link to comment Share on other sites More sharing options...
sailone32003 Posted April 25, 2014 Share Posted April 25, 2014 Just checked mine all is good. Thanks guys Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Manik Posted September 24, 2014 Share Posted September 24, 2014 Just found this online: http://www.troublecodes.net/Nissan/88-9495pthqust/ The CEL came on on my way to work this morning. Used this thread to diagnose the issue, but, this site to define the code. The code that is being "tossed" is a 34, happens to be a knock sensor, not gonna worry about it til it becomes an issue. The question is, will it? I'm unsure, but, guess I'll find out. Any other clues? Redneck, GEARHEAD, fabricator, are just a few of my "specialties".... Bubba says it all!!

Supererogator Posted January 20, 2015 Share Posted January 20, 2015 I have owned my Pathy for just about four months. This has been one of the most valuable things I have found while making her better. Thank you so much. This is way easier to find than the book version I own, for some reason.

Precise1 Posted January 20, 2015 Share Posted January 20, 2015 You did download the FSM from the Garage section as well? That way you have hard copy, PDF and web based info... B Link to comment Share on other sites More sharing options...
Guest johnnjanet Posted July 14, 2015 Share Posted July 14, 2015 my 95 gives me an error code of 51 means injector circuit. How do I find out if it is only one injector and which one or should I be looking at the main feed? Link to comment Share on other sites More sharing options...
Slartibartfast Posted July 14, 2015 Share Posted July 14, 2015 If you can trace the wiring in the EL section of the service manual, you'll find the plug for the injectors, and from there you can check with a multimeter to see which injector isn't reading right. IIRC it's one of the plugs on the thing sticking up from the passenger's valve cover. Link to comment Share on other sites More sharing options...
wendy Posted January 21, 2016 Share Posted January 21, 2016 what is a mech-v260-a1-4831 'how get codes off mecm v260', engine light on, I have pulled the seat, but can't find any lights or tabs...Help I can't get my car smogged Link to comment Share on other sites More sharing options...

k9sar Posted January 22, 2016 Share Posted January 22, 2016 there should be 2 led's facing the rear seat, one red and one green... unless your ECU is different than mine. I've never looked at the 'model' and just assumed all of the 94/95's were the same Link to comment Share on other sites More sharing options...
Pathfinder65 Posted November 2, 2016 Share Posted November 2, 2016 Thanks for the info provided in this post. I had no idea there was a unit under the passenger set. The last person who owned the vehicle put carpet over the unit and it could not be seen until I removed the front seat and pulled the carpet back. Code shows Crank Angle Sensor/Camshaft Position Sensor error (1-red, 1-green), after checking prices on the sensor, im hoping there is something else going on and it dont have to be replaced. Any suggestions will be greatly appreciated. Link to comment Share on other sites More sharing options...

Is this an issue or should I live with it? Thanks For the Diagnostic Info It is really helpful and well done. What does EGR mean in laymans terms.

Slartibartfast Posted January 31, 2019 Share Posted January 31, 2019 EGR = Exhaust gas recirculation. It pipes exhaust gas into the intake when you're cruising to make the engine run a little more efficiently. The power output of an engine depends on how much air it can suck in (and mix with fuel and burn). You control the engine's output using the throttle, which is just an air valve. When you're cruising, the throttle's not open much, and the engine isn't putting out much power. Foot to the floor, the throttle's wide open, and the engine puts out everything it's got. There's a problem with this. When the throttle's not fully open, the engine is fighting for air, and that fight causes what's called pumping loss. The engine is fighting to breathe, and that fight is wasting energy. To reduce pumping loss, we can let the engine breathe something that isn't air to make up for the air we don't want it to have. Exhaust gas is basically inert as far as the engine cares. It's burned already. It doesn't change the fuel mixture--it just fills space. Basically, it makes a big engine at partial throttle act more like a little engine running wide open by filling the displacement the engine isn't using with exhaust gas. The computer shuts off the EGR when you floor it, of course, and also at idle. From what I've read, these do run a little better with the EGR system than without it, provided it's working properly. Mine works, so I haven't had a reason to mess with it beyond replacing the vacuum lines and cleaning out some carbon deposits (it is exhaust gas, it isn't exactly clean) when I had my intake off anyway. There's a diagnostic procedure in the service manual if yours is acting up or throwing codes. Link to comment Share on other sites More sharing options...
Josh_Path2346 Posted April 18, 2020 Share Posted April 18, 2020 My 1988 Pathfinder VG30i gave me a 55 (no malfunction) today, however there is a vacuum leak that might be causing the idle do rev up and down (approximately 1700-2500). I chased it down to behind the throttle body. Should I take it off and try to tighten it down again or look for something else? Link to comment Share on other sites More sharing options...
