Hey guys, So the Sentra is finally all back together and running. Only problem is theres an idle bounce. I brought it to my friend and he grabbed these codes. He wasn’t sure what they could be. He was thinking a vacumme leak. The car idles (bounces) between 1000 and 2500. Any idea guys? Thanks in advance ![http://img.photobucket.com/albums/v738/rugsr/Sentra1.jpg](http://img.photobucket.com/albums/v738/rugsr/Sentra1.jpg) ![http://img.photobucket.com/albums/v738/rugsr/Sentra2.jpg](http://img.photobucket.com/albums/v738/rugsr/Sentra2.jpg) ![http://img.photobucket.com/albums/v738/rugsr/Sentra3.jpg](http://img.photobucket.com/albums/v738/rugsr/Sentra3.jpg) ![http://img.photobucket.com/albums/v738/rugsr/Sentra4.jpg](http://img.photobucket.com/albums/v738/rugsr/Sentra4.jpg) [http://vimeo.com/28456262](http://vimeo.com/28456262) ---

don’t know of any sentra specific issues, but I’d verify there are no vacuum leaks, clean the TB and IAC which is what I presume is what controls the idle vs. a throttle plate stepper motor. What has been done to it recently? ---

You need to do the Idle relearn procedure…gimme a minute and ill find it for you ---------- Post added at 09:15 AM ---------- Previous post was at 09:12 AM ---------- How To: Idle relearn w/ video Note: Timing in this procedure is critical in order for it to be successful. PREPARATION Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied. Learning will be cancelled if any of the following conditions are missed for even a moment. - Battery Voltage: More than 12.9V (At idle) - Engine coolant temperature : 158-203°F - For A/T vehicles: PNP (Park/Neutral Position) switch: ON - M/T vehicles: Neutral switch: ON - Electrical load switch: OFF(Air conditioner, headlamp, rear window defogger) \*On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is started, the headlamp will not be illuminated. - Steering wheel: Neutral (straight-ahead position) - Vehicle speed: Stopped - Transmission: Warmed-up (Drive vehicle for 10 minutes) OPERATION PROCEDURE Without Consult-II NOTE: - It is better to count the time accurately with a clock. - It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction. 1. Perform “Accelerator Pedal Released Position Learning” a) Make sure accelerator pedal is fully released. b) Turn ignition ON and wait at least 2 seconds. c) Turn ignition OFF and wait at least 10 seconds. d) Turn ignition ON and wait at least 2 seconds. e) Turn ignition OFF and wait at least 10 seconds. 2. Perform “Throttle Valve Closed Position Learning” a) Make sure accelerator pedal is fully released. b) Turn ignition ON. c) Turn ignition OFF wait at least 10 seconds. Make sure that throttle valve moves during above 10 seconds by confirming the operation sound. 3. Start engine and warm it up to normal operating temperature. 4. Check that all items listed under the topic “PREPARATION” (previously mentioned) are in good order. 5. Turn ignition OFF and wait at least 10 seconds. 6. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds. 7. Repeat the following procedure quickly five times within 5 seconds. a) Fully depress the accelerator pedal. b) Fully release the accelerator pedal. 8. Wait 7 seconds, fully depress the accelerator pedal and hold for approx. 20 seconds untill MIL (Malfunction Indicator Lamp, a.k.a. SES light) stops blinking and is turned ON. 9. Fully release the accelerator pedal within 3 seconds after MIL (SES) turned ON. 10. Start engine and let it idle. 11. Wait 20 seconds. 12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications. * * * ITEM SPECIFICATION * * * Idle speed 700±50 rpm * * * Ignition timing 15±5° BTDC * * * 1. If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried out successfully. Further diagnosis may be required Heres the video for you if your a visual learner. ---
