How To: Idle Air Volume Learning (Easy Way)
Anytime the Electric Throttle Control Actuator (Throttle Body) or ECU is disconnected from the wiring harness, the idle speed will need to be re-learned. This procedure can also resolve a high idle at park or in neutral of over 1500 RPM and a pulsating idle that goes high and drops low repeatedly. The idle for the Nissan Versa should be between 650-750 RPM at park or in neutral. The official procedure can be found here; however, I found that this procedure is very time sensitive and it was much easier to perform it the following way.


* Stop Watch or Stop Watch App for Smartphone


1. Drive Versa for 10 minutes to warm up the engine and transmission.

2. Turn off Air Conditioning, Headlamps and Rear Window Defogger.

3. Put Versa in park, straighten out steering wheel (neutral position) and turn off vehicle.


* The following procedures are time sensitive and if messed up, must be started from the beginning. It may take a few tries to get it right.

1. Turn the ignition switch (key) to the off position and wait 10 seconds.

2. Turn the ignition switch (key) to the on position and start the stop watch at the same time. (The on position is the second click)

3. At 3 seconds on the stop watch, press the accelerator pedal fully to the floor and fully release it 5 times before the stop watch gets to 8 seconds. (Timing wise, all that matters is it gets done 5 times between 3 and 8 seconds on the stop watch)

4. At 15 seconds on the stop watch, press the accelerator pedal fully to the floor and hold it down.

5. At 35 seconds on the stop watch, fully release the accelerator pedal and then immediately start the engine.

6. At 60 seconds on the stop watch, rev up the engine 2-3 times and make sure each time the tachometer falls back down to 650-750 RPM.

7. Turn the ignition switch (key) to the off position - idle is now set.

Thanks PopTech, I just got the P0507 CEL today, so I'm going to clean the throttle body and perform the relearn procedure. I appreciate the summarized version.

I performed this procedure today and it worked like a champ. It cleared the P0507 code as expected. Thanks Again Poptech.

Great how-to, thanks Poptech.

I performed this recently and the "Service Engine Soon" light began blinking erratically. I turned the car off, pulled the ECU fuse, put it back in, and it went back to just being solid.

Anyone else have this happen?

I guess it is a time to disconnect NEG battery terminal for a few minutes, and then to drive for a while.

I have a 2007 hatchback with 101k miles. I changed the spark plugs last month and have had this coffee since . I've tried the relearn several times with no improvement. Bought a used throttle body to try for fun with the same issue. I've had a mechanic tell me to replace the first pump because this will also improve the bad mpg. (I get about 30) what should I do next? Tx, Bill

I have a 07 manual trans versa s with 104K miles. It idles up and down when its in neutral.
I first checked all hoses for crack or vacuum leak found none.
I clean the original trottle body assemble and perform the relearn technique No fix. So I replaced PVC valve, 4 spark plugs, new trottle body and perform the relean technique . The car still idles up and down.
Does anyone have any suggestions?

If the up and down is within 100 rpm it can be normal if you are running a/c on an older engine. The a/c kicking on and off does it. It does not show until the engine gets more miles on it as new engines maintain idle speed better than old when you switch the load on and off.
