My 2003 Maxima has 105k.

I recently switched out the Cam position sensors. That fixed the symptoms which are usually associated with that problem.

So, now I have the SES light and the P0507 code.

Are the cam sensor issue / repair & the P0507 code related?

NOTE: I also watched the mechanic wipe the inside of the intake with a rag to clean a sensor or something while the air box was off.

How do I tell if I need a new throttle body as opposed to just the 'Idle air Volume Relearn Procedure' performed?

I have a feeling by reading stuff here at Maxima.org that these issues are related and that I do not need a TB, just the relearn procedure.

In the past I have had great success finding qualified & affordable people to perform repairs on my cars including this one.

(Any insight on this? Or anyone in the Clearwater FL area want to deal with this?)

AUTO GIG: Perform 'Idle air Volume Relearn Procedure' 2003 Maxima


posting body;
I have a 2003 Maxima with 105k on it.

I recently switched out the Cam position sensors. That fixed the symptoms which are usually associated with that problem.

Now, the new problem that might be related; I am getting a check engine light and a P0507 error code. This is "Idle Speed Control System RPM Higher Than Expected".

My research shows that the car needs the 'Idle air Volume Relearn Procedure' performed.

I would prefer a maxima enthusiast that knows about this really well, and has performed this procedure multiple times.

Also prefer someone located very closely geographically to my place which is the Tri-City plaza area of Clearwater.

PLEASE INCLUDE YOUR LOCATION AND PRICING IN THE SUBJECT LINE OF YOUR RESPONSE.


This page at Maxima.org suggests that a procedure;

Here is the procedure which it suggests;

If that is the only code from a 2002-2003, you can try the idle air volume relearn procedure.

Tough to read, find the FSM and look in the EC.pdf.

Without CONSULT-II
NFEC1188S0302
NOTE:
I It is better to count the time accurately with a clock.
I It is impossible to switch the diagnostic mode when an
accelerator pedal position sensor circuit has a malfunc-
tion.
NOTE:
Before perform “Idle Air Volume Learning”, make sure that “Accel-
erator Pedal Released Position Learning” and “Throttle Valve
Closed Position Learning” are completed.
If not, perform “Accelerator Pedal Released Position Learning”,
EC-71 and “Throttle Valve Closed Position Learning”, EC-71.
1. Start engine and warm it up to normal operating temperature.
2. Check that all items listed under the topic “PRE-CONDITION-
ING” (previously mentioned) are in good order.
3. Turn ignition switch “OFF” and wait at least 10 seconds.
4. Confirm that accelerator pedal is fully released, turn ignition
switch “ON” and wait 3 seconds.
5. Repeat the following procedure quickly five times within 5 sec-
onds.
1) Fully depress the accelerator pedal.
2) Fully release the accelerator pedal.
6. Wait 7 seconds, fully depress the accelerator pedal and keep
it for approx. 20 seconds until the MIL goes off.
7. Fully release the accelerator pedal within 3 seconds after the
MIL goes off.
8. Start engine and let it idle.
9. Wait 20 seconds.
SEC897C
10. 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
MT: 625±50 rpm
AT: 675±50 rpm (in “P” or “N” position)
Ignition timing
MT: 15±5° BTDC
AT: 15±5° BTDC (in “P” or “N” position)
11. If idle speed and ignition timing are not within the specification,
the result will be incomplete. In this case, find the cause of the
incident by referring to the “Diagnostic Procedure” below.
 
DIAGNOSTIC PROCEDURE NFEC1188
If idle air volume learning cannot be performed successfull
proceed as follows:
1. Check that throttle valve is fully closed.
2. Check PCV valve operation.
3. Check that downstream of throttle valve is free from a
leakage.
4. When the above three items check out OK, engine com
ponent parts and their installation condition are question
able. Check and eliminate the cause of the incident.
It is useful to perform EC-152, “TROUBLE DIAGNOSIS
SPECIFICATION VALUE”.
5. If any of the following conditions occur after the engin
has started, eliminate the cause of the incident and pe
form “Idle air volume learning” all over again:
− Engine stalls.
− Erroneous idle.

 

Did you try relearning it with the pedal dance?
Alternatively, you can use a bluetooth obd2 adapter and car gauge pro to do it. It's a little tricky as it says it fails, but it works if you exit the app as soon as the idle resets.

The mechanic ****ed it up. Make him fix it. If you move the butterfly valve it can cause this. It's not a coincidence. No reason to pay for his **** up.

 

Thanks very much for your response and the Car Gauge Pro tip. I think I am going to order an ELM27 off Ebay and try that. Can you give any procedure or any steps I need to take to use that software / app to fix this?

Does anyone know if the 'Garmin Machanic' app along with the Bluetooth Garmin ecoRoute HD Vehicle Diagnostics Communicator can accomplish what I need to do?

Thanks again, any additional information appreciated.

 

You should not need a new TB. Unlike the 5-Gen, the 5.5 Gen Maximas (2002-03) have an electronic throttle and an Idle Relearn is required if/when/after you touch or otherwise disturb the throttle plate. It seems that your mechanic was not aware of this issue. So, you could go back and have him fix it, but do you trust him to do it properly? Do you trust yourself? In either case, the dealer should be able to; perhaps you can negotiate a decent price with him.

 

Well, that sounds like good news.

All the written instructions which I have seen that describe how to perform the relearn seem VERY long. It just looks like there are SO many steps. I cannot imagine getting it exactly right. If it is my last resort, I will certainly give it a try sometime when I am in a mood which would be conducive to a VERY high tolerance leven for frustration. I have seen instructions which seem to indicate that removal of spark plug wires is required, while others do not seem to require that.

I have seen a couple posts which describe android applications which, when paired with a bluetooth OBDII tool will clear this up.

Not to ask too much, but I would love to see a video of someone using one of these apps to do the relearn process. Or, once I have the application is it just as easy as 'press here to do the relearn' or is there a bit of knowledge or a learning curve to using the app(s)?

As far as the mechanic causing the problem, yes. I believe that is what happened. I really like the guy. He definitely did not mean to do it. I really doubt if he knows the relearn procedure, nor has the equipment to fix it. I will tell him so he does not do it again to anyone elses car.

Heck, maybe I will get lucky and someone in the shop will be able to help me. But, I am definitely not counting on it.

 

This is a ridiculous attitude. After a couple tries I was able to do the reset/relearn procedure. I can do it anytime 1st try from memory. If you know how to count properly, then it's easy (one one thousand, two one thousand, etc).

You could have probably solved this within 10 mins if you would just do it.

Warm the car up to operating temp and have the doors closed, then follow the pedal dance instructions.

 

Okay, oaky. Thanks for the motivation. I have posted some instructions, which I found, in my original post. Can you tell me if these are correct instructions? Do you know of a presentation of these instructions that is any more 'well presented' or clear?

 

I would do all of these in order as listed http://www.nicoclub.com/archives/g35...-learning.html

 

update, OP?

 

I have not tried the steps you linked to. I notice that the link you sent is for a g35. Same steps for my 2003 Maxima?

I just received my bluetooth OBD II scanner.

I am about to download the applications listed / recommended above. I might record it and put it on youtube.

It seems like my gas mileage is suffering since I started having this error? Does this affect mileage?

The SES light stayed off for a good few days the last time I hit it with my handheld OBD2 scanner.

 

I tried 5 applications. They either did not have an 'Idle Air Relearn' feature, or would not properly connect to either my garmin OBD2 scanner, or the one that I bought on Ebay. The apps I tried were Car Gauge Lite, Torque(free), OBD Car Doctor, NDSII Lite, Garmin Mechanic.

 

Some of them don't work b/c they're made too cheap
Car gauge pro has the feature. That's what I use.

The pedal dancing is the same for all nissans, so yes, the instructions will work.

 

Please let me know what make, model & source of the adapter you use to successfully perform the idle air relearn?
