Any help with these codes?

Hi all, I have a '02 330i and it's been having an issue but now won't drive at all.

The codes we have found are
P0221
P1632

The car will start but not move - RPMs fluctuate on their own up to 1500 - up and down.

Can you help?

Thanks!
Anne

Those are throttle pedal and throttle body adaptation codes.

What work was performed just before these codes showed up?

These are not common failures that just happen out of the blue.

Both of those codes appear to be the same thing. P0nnn codes are called generic codes. All cars that make this code make it for the same reason, it is generic. P1nnn codes are unique codes. A Ford or Chevy, for example, could make the same P1nnn code, but the reason is different for each of them and different than the reason BMW makes it, it is unique.

P0221 = Throttle/Petal Position Sensor/Switch B Circuit Range/Performance Problem
P1632 = Throttle Valve Adaptation; Adaptation Condition Not Met


Maybe these are not the same thing, like a tomato and a tomahto, but they are related. Your car is telling you that it does not know where the gas pedal is. Your car has a drive-by-wire system, there is a sensor on the gas pedal and a motor on the throttle body. You push the gas pedal and this sends a signal to the computer that then turns around and tells the throttle plate how far it should open. I'm gonna guess here that you need the sensor on the gas pedal, but what you really need is more diagnostic information.

Take your car -- if you are not gonna attempt repairs at home --to Scott at Sterling Autosport. He's located in the neighborhood behind Siggy's on Jefferson Ave.

+1. These are not common failures. If there was work done, then it could be linked.

Hi jd, thanks for that name, it will help tremendously. My hubby could do the work but it's nice knowing we have an option.

The only work we have done on the car since we owned it is change the oil and change the tires. Also, since this started happening, hubby has been trying resolve but he only cleared the MAF sensor (I believe that's what he called it).

It started happening slowly, where it was occasional. You could turn off the car for 20 seconds, then turn back on and it would be fine. Even last week, it was working OK again. By Friday it would not run.

Personally with the small bit of information you provided, I think there may be more to the story??

I would recommend that the throttle cable be unplugged and plugged back in before I took any further action? This assumes someone has been down this close to the throttle body. This is a simple and easy, no cost thing that can be performed fairly easily.

It is not clear if the MAF sensor cleaning task was performed for this problem or if this problem is a result of the MAF cleaning for some other reason or other problem?

Had the car been detailed or to the full service car wash before any of this happened?

Just trying to understand what happened just before this all started.

Try this and see if it helps the situation??

Turn the key to position "2". Position "2" is one position before the car engages and starts, do not start the engine.
Wait 10 seconds and then turn the key back to position "0", which is the initial position.
Once again wait 10 seconds and then start the car up.

This procedure is supposed to reset/adapt the throttle??

Something I have found, not sure how accurate it is.

Just because it isn't a common failure does not mean it can't happen. It can happen, that's why they gave it a code.

Your description of the symptom set fits the code. I have not seen the code before, but I have seen things happen that come on slowly, and if ignored long enough the car eventually stops altogether. There is a P0340 code that hs to deal with a cam sensor, it often will fail in a manner similar to what you describe -- we turn the car off and back on, and it works for days or hours. I only bring this up to support your experience that the car would self-correct by shutting it off, until it finally fails completely.

I have no experience with the reset that jfoj is talking about, but it can't hurt. Give it a whirl.

Well, I did mention that this had been happening for awhile. We read a lot about the symptoms and tried to resolve the easy parts - MAF being one of them.

It hasn't gone through the car wash either. or been detailed.

One thing my hubby told me to mention, in case it matters.... the car did not get driven much - twice a month to the airport and back (60 miles each way) and daily school runs. Occasionally additional trip to my folks (45miles) - anyhow he wanted me to mention in case it could be a factor somehow.

I will try the reset. I know we saw one online that said turn to that position for 60 seconds to recalibrate the throttle but that did not help

Thanks so much for all your responses.

Me thinks you need to take the car to Scott. My instinct is that the throttle position sensor on the gas pedal is toast. I suppose if you can buy one for 50 bucks or whatever (relatively cheap) and put it in by yourself, and this fixes it, then you don't need Scott. I can't recall anybody ever reporting this problem, so I really don't have very high confidence that it is the problem, although the codes point to it. I can't argue with the codes.

I have high confidence that you only have one problem though. One problem, two codes. More correctly, same problem reported twice.

Well we bought the new pedal, part # 35426786282-01 and fitted it today with no luck Somebody mentioned I should find the throttle cable and unplug and plug back in . Trying to find this cable is it visible or do we have to remove bits before we can see it?

I'm not sure where it is hiding, but I would expect that the air cleaner box would need to be removed to gain access to the throttle body.

Back in the olden days, you pressed the gas pedal with your foot, this moved a linkage that connected to the throttle plate and pulled the plate open so more air would enter.

The way they do this on your car is that you press the pedal, this causes a signal (from the part you replaced today) to be sent to the computer, which then sends out a signal to a motor that opens the throttle plate. You should be able to identify the throttle plate, what you are looking for is the wire that plugs into the motor that moves the plate as you change your foot position on the gas pedal.

Sorry for delay, just getting back to this after Christmas.

On the way in to clean the TB we took out the DISA and intake boots and have ordered new intake boots.

1) The DISA is dirty, oily crud. Can this just be cleaned, if so what's best to use?
2) Our plan is to clean TB using TB cleaner and then put her back together to see if that was it.

If not we'll buy a new TB. Is there anything else we should do/replace etc whilst we're in there?

Thanks

Have you searched here and google for your codes? That always helped me find solutions. Here, search for both codes together and individually in advanced/title search.

If you're cleaning TB, might want to replace gasket behind...if removing it, which is best way to clean it. In the car, be sure to let things dry out before starting the car...and while at TB, replace lower boot (you can thank me later!)...disa o-ring (clean with TB cleaner too). If it's that bad, someday look into CCV as that might explain why disa is so oily.

Sorry I can't help more. If I knew more, I would...if I was currently single and you were too, I might also!

So you got pedal and that didn't work...assuming it was OE and new. Only other thing I'd say is don't assume the codes mean 'exactly' the same thing...maybe they do, but another thing.

Check realoem.com ...either pedals or maybe trans...for some throttle position thingy.... Maybe there's a relay or the like?

I'm pretty sure there's another sensor besides those on the pedal itself, but maybe not? Tell hubby to make sure he plugged whatever in...and ask him nicely...and then afterwards, for all his hard work, you really should treat him very nicely! Just saying!

Also, tell him that instead of you reading Fanatics until you're nauseous, that he should. Be careful here, please. This forum is safe for you...your regional forum, or OT, definitely not. Totally inappropriate communications go on there. Just stay here and all will be fine. Your husband, on the other hand, might really enjoy OT...tell him to say "hi" to Griffin for me. He's sort of our national treasure!

Good luck with your car...and don't worry...if I know something, I'll help if I can!

Update,

So as we await delivery of new intake boots today hubbie took out the icv and cleaned it up and reinstalled it. He also started to clean the TB but when I press the throttle down from inside the TB plate doesn't open. When I turn the key to the second position(dashboard lights) the throttle plate opens about 1/4 inch but no more, even when I press on the throttle. He had read that as this is a drive by wire (2003 330i) he shouldnt push on the plate with his finger in order to open it. When it opened that tiny bit he sprayed TB cleaner in there. Should that plate open to the horizontal position when throttle is pressed inside the car or is this correct?

We swapped out the throttle pedal for the new one thinking maybe that was it but it made no difference We're thinking the a new TB is in our future.

Before you pull the trigger on a new TB, I would suggest taking the old one out and cleaning it. In my 00 E46 323i I had an issue in which my TB was sealed shut because of accumulated carbon build-up. After I cleaned it and made sure it was opening properly my issues also went away. Just a thought!

Yes, its a very simple process, in my case I needed the tap of a mallet and chisel to reopen the flap in order to clean it thoroughly. Let us know if the TB cleaning changes anything!
