    I have the same problem, but I found that this is because the airsensors located on the catalyzer which is part component os the muffler, and this interfere with the emissions fuel system and turn this light on, i've been for 5 years with the light, there is no problem, until you need the smog check

I've had this issue and had the engine codes checked. It was a coil wire in one of the cylinders (nissan has ignition coils instead of the old plug wires) and this will fix the misfire if in fact that is what it is. To tell if you are misfiring, does the car idle smoothly? Does it misfire and kind of shake while driving where only pushing the gas peddel takes the problem away? Does the car feel like it may stall? Have it checked as if you don't and it continues it could burn out the catalytic converters and those are expensive on the nissan as there are multiples.

There are many parts stores that will run the diagnostic codes for you for free. Call around and see.

They should be able to tell you why the service engine soon light is on.

99 Nissan pathfinder wants to start but won't. Within the last 2 months I have had a tune up, new distributor, new battery and connectors and new rack & pinion. Now getting a P1320 error for my...

That code shows a problem with the Ignition Control Module. Specifically: ICM, 4X Reference Circuit Intermittent, No Pulses.
Sounds like either a bad module, or the computer signal (reference signal or circuit?) may be a problem. If it's in the wiring, likely a shop will have to diagnose it.

Service engine soon light is on because the computer has found an error, and may not have anything to do with oil. Get it scanned to see what the diagnostic trouble code is.

How do I reset the service engine soon indicator of a 2007 nisssan pathfinder

The Service Engine Soon indicator light tells the Service tech that the Pathfinder's ECM detected and Issue with the engine's management system. Your going to have to get the Pathfinder Scanned for DTC codes so you can addressed the issues that is in the ECM's history. Once the issues have been addressed, the Service engine light will reset it self or the service tech can reset it for you. The light will stay on or come back if the issues have not been repaired. Good luck and hope this helps.

Service engine soon

The "Service engine soon" light pertains to oil change frequencies only, there is no code, it will come on at given milages to remind you to change your oil. To reset there should be a small hole in the face of the instrument panel. Remove the tiny plug and push a paper clip into the hole with a slight force until you feel a click. This should reset the light for another 3000 miles. If it does not have the hole than it must be reset by the dealer. Thank you, Dana

Does this cost money

This happens when your odometer reaches a set milage,indicating mantainance.Just what needs service I don't know.If you do nothing your check engine light will stay on soon.Many Pep Boys, Auto Zone will read your onboard diagnostic for nothing ( a small Tip is expected ).Then you'll know what it is.Don't rush into repair.Get estimates.It could be very minor..Filters or mid... EGR Valve ,Cat Converter.Good Luck

Missing oil

very common problem you are burning oil. the piston rings, that nissan used are the problem. We see quite a few of the 3.5 liter engines loosing oil due to piston ring problem. nissan sais that 1qt. per 3500 miles is exceptable, but who want a vehicle that burns oil?? not me. good luck with that.
