fusion Posted March 4, 2011 Share Posted March 4, 2011 Hey everyone. So, my check engine light came on today and I am little surprised to say the least. My Pathfinder runs really well and I average about 19 mpg. No funny behaviors or noises. About 100 miles ago, I installed the Warn manual hubs. Could this be the cause of the CEL? Does anyone know a way to get the computer to spit the codes out other then having a diagnostic tool, via blinking light or any other way? Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted March 4, 2011 Share Posted March 4, 2011 I think a code reader is the only way. I highly doubt the CEL has anything to do with installing manual hubs. Could be any number of things. Best bet is to take it to a shop (ideally an indy shop over a dealership) and have the codes pulled. Link to comment Share on other sites More sharing options...

Yeah, I know a guy who was an Infiniti/Nissan tech for a couple decades then opened his own mom and pop. I'll have him pull the code tomorrow morning... he isn't local though and driving that far running a CEL is a bit nerve-wracking. Some other work I have done in the last few months on the rig are: an AC lift, cb radio, custom cat-back flowmaster exhaust, K&N filter, PIAA bulbs, new front and rear clear light housings, new wheel bearings, oil/filter change and some other stuff. I don't think any of that would cause a CEL though, at least, not that I know of. Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted March 4, 2011 Share Posted March 4, 2011 AFAIK, I doubt any of those mods would throw a CEL. My guess is a sensor has decided to crap out. The only issue is knowing which one so getting codes read becomes absolutely paramount at this point, Link to comment Share on other sites More sharing options...

The only issue is knowing which one so getting codes read becomes absolutely paramount at this point, I agree, it could be something like an O2 sensor (that was always my issue), or even something as simple as your gas cap not on tight. I understand a CEL light is most often an emissions issue. Link to comment Share on other sites More sharing options...
big_johnson Posted March 4, 2011 Share Posted March 4, 2011 ...or even something as simple as your gas cap not on tight. This is what my last 2 CEL's have been. Fortunately, I have a Scangauge to read my codes! Link to comment Share on other sites More sharing options...
