Guest manualfreak Posted June 14, 2006 Share Posted June 14, 2006 Howdy everyone. I have got a manual 2002 pathfinder. The check engine light comes on (and stays) after I drive on highway with cruise on. After it happened the first time I went to a mechanic I know and he said it's oxygen sensor #2 and zeroed the thing. But after 600-700 miles in a similar situation it went on again. Do you guys have an idea why this is happening? Is the sensor really faulty or do you think it's because when a manual car goes on cruise uphill, since the gearbox cannot kickdown, the gas-air mixture becomes richer in gas (and poorer in oxygen), which triggers the sensor to send a signal? Many thanks for your responses. Link to comment Share on other sites More sharing options...
94extreme Posted June 14, 2006 Share Posted June 14, 2006 you didn't tell us how many miles are on the rig but i bet you that the o2 is a gonner. never seen one of these codes without a good reason. btw. welcome and do you wanna trade? http://www.nissanpathfinders.net/forum/index.php?showtopic=9450&hl= :D Link to comment Share on other sites More sharing options...
navygz19 Posted June 14, 2006 Share Posted June 14, 2006 btw. welcome and do you wanna trade? http://www.nissanpathfinders.net/forum/index.php?showtopic=9450&hl= :D Just when you thought there weren't enough Manual tranny owners... The o2 sensors on our rigs are terrible. 01-04's are particularly prone to this. I'm just waiting for my light to come on because of this. Link to comment Share on other sites More sharing options...
Terminex Posted June 14, 2006 Share Posted June 14, 2006 Same thing happened to me about a month ago. tried just resetting the light. then I started tracking my gas mileage - 13.5 FREEWAY:-( Took it to the dealer and had 2 O2 sensors replaced & the computer reprogrammed. replacing those bad O2 sensors brought me back to 15.5 mixed driving. (lucky for me my extended warranty doesn't expire till next month:-) Link to comment Share on other sites More sharing options...
tecciball Posted June 14, 2006 Share Posted June 14, 2006 i have an 01 with 48k miles that experienced the same problem for about a year. i think the code was p0158 - rear driver's side o2 low voltage. ses would come on only after highway cruising for at least an hour. it would go off eventually or when i reset it with the scanner. next time i was on the highway it would come back on. all the while, i was getting pretty bad gas mileage. about three months ago, i changed the o2 ($85 i think) and put in a k&n drop in filter ($45 i think) and now i get 19 to 20 mpg on the highway and probably 14 to 15 city which is normal. i am also jealous of the manual tranny. but my better half cant drive one.

navygz19 Posted June 14, 2006 Share Posted June 14, 2006 Can you use pre-'01 (think, VQ) sensor's on a VQ powered Pathy? :confused: If so, a yard might be a place to start for cheap replacements. Older R50's are much easirer to find... Link to comment Share on other sites More sharing options...
5523Pathfinder Posted June 14, 2006 Share Posted June 14, 2006 There is a tsb to replace the rear o2 sensors and reprogram the ECM if your ecm part number is affected. Your factory 8 year, 80,000 mile ecm warranty might cover this. The number is NTB03-011. Its pretty common repair, and hey, it might be free! Your ecm has a part number that is printed on every printout from the scan tool at the dealer. Find out what yours is and look up the tsb. Link to comment Share on other sites More sharing options...
maximusnt Posted June 15, 2006 Share Posted June 15, 2006 Can someone *please* post this TSB! Link to comment Share on other sites More sharing options...
navygz19 Posted June 15, 2006 Share Posted June 15, 2006 Can someone *please* post this TSB! Is this what your talking about? TSB Not sure if that's the one or not. Though, I can't find anything else related to '02 Pathy's o2 sensors. The only other one involves the SES staying illuminated on 2005+ Pathy's.
