Question about 2002 Nissan Sentra

1 Answer

My 02 sentra ser spec V runs fine if it is under a load and while accelarating but at an idle it keeps jumping up between 1000 and 2500 rpm for a few seconds before finally settling in at around 1200 rpm. it has the check engine light that comes on sometimes steady, sometimes flashing, and occasionaly not at all. the problem is persistent regardless of the check engine light. just wondering if i should look at the throttle body or if its something more simple. any help is greatly appreciated.

Idle speed control valve located on your throttle body. It has the engine searching for idle, internal plunger is not backing down. This will cause the check engine light to light . if you wont, i think they still offer free check engine light checks at auto zone, i now they still do around here

What causes a rough idle on a 2003 Nissan Sentra Spec-V? Car otherwise runs fine while driving.


The rough idle is associated with the p011 code. The P011 code is: Camshaft A over advanced. There is a mechanical fault with the intake camshaft.
You need to take the car into a mechanic, preferably the dealer since they have all of the needed special tools, to properly diagnose and repair the issue.

Under 2000 rpms runs bad/hesitates/check engine light


This IAC valve runs only when your foot is off the gas pedal. Mainly to keep the engine from stalling and keeping it at a safe RPM. If it is running bad under 2000RPM, more than likely its the IAC valve or a vacuum leak. Clean or replace the IAC valve....Hopefully this helps!!

I have a 2002 nissan sentra SE-R. when the engine is really hot, it dies in idle, the idle is 600 RPM, i guess the idle is too low. So I have to rev it when im at the stop light or double pedal if i make...


Got the same make/model/year, but haven't had that problem. Does your temperature gauge run at half or above when this happens? If so, start with a cheap fix - new thermostat.

Another thing to consider is that some of the QR25DE engines equipped in the 02 Sentra SERs has an active recall on the crank position sensor. This fault would cause the check engine light to come on and the car would stall unexpectedly. It should start back up but the frequency of this will only increase without repair.

Also, no need to change plug wires, you have coil pack ignition - there is no distributor. If a coil pack is bad, you will have constant misfire and SES light.

2002 Toyota Tundra Stalls


The throttle body needs cleaning. It has some carbon build up, and when the battery went dead the computer lost its learned values, one of which is base throttle position. Now its reset back to factory specs, not accounting for a dirty throttle body. Seen it a million times
