    OPCODE: 08452001 Sensor, air flow/air intake/air temp: sensor 5174042AC. Chrysler has issued a service bulletin for mechanics on this one. The dab of paint on this little 1.5 inch long device must be of the right color said Mr. Mechanic.

    The one in my vehicle came on 10 minutes after leaving the dealership with my new purchase! They fixed it right away.

    The stock speaker positions in the rear area are on the sides about half way back. So far as I know, the position will not have wires unless you ordered them to be wired or got the van with the rear speakers. Anyone who knows other wise, please jump in...

    the tiny grills in the back are for the stale air exhaust vents which are often found in the rear of vans and cars, often in the rear pillars.

    I have a plan to add two or four small monitor speakers, like the JBL Control 1A speakers, and then add a powered tube sub-woofer. Still don't know about the in-dash speaks... maybe some 4 ohm wide-range drivers that I know of from AURASOUND

    It seems intelligent to use the open post, add a fuse, and run the wire as suggested for the safety factor of being fused from the post to the isolator.

    my added $0.02

    The stock rears are located in the middle of the rear panel and aim between the two rear seats. Definitely not optimum. I doubt the wires are there. You can't put a woofer under the driver's seat as it's jam packed with electronics. The passenger side is empty and you could fit a single 8" custom made box there. I had the best shop in the Boston area; Rich's Cartunes do the design and install. It was funny seeing my Sprinter in the shop with a Bentley Continental and a Ferrari next to it. Interestingly I got more questions about the Sprinter with the Mercedes logos than the Bentley did (boy that's a handsome car). Good luck!

    Again, thank you KenB; very helpful info as always.
    I'll probably end up going to a local (independently owned and operated) auto stereo shop, as I lack the time and expertise to do the job myself.
    (If anyone knows of a good shop in Ventura County, CA, I would appreciate the referral.)
    But I have to do it soon; I don't know how long I can endure that stock CD player and those tinny dash speakers.
    Thanks again,

    Thank you, very much, for the good info.
    And thanks also for your post #437; I will take your specs to an auto stereo shop.
    I wish Cartunes were in my area.
    If anyone knows a good independently owned and operated shop in Ventura County (CA) I would appreciate the referral.
    Thanks again!

    On my first tank in my new 118" passenger van I got 21.91 MPG. That's mostly highway driving, with the rear bench seat removed, with the stock 15" rims and tires.
    I'm changing to 16" wheels next week, and hoping my MPG will improve. (But I guess my odometer will also register fewer miles per tankful with the larger circumference tires, so it will be somewhat of a wash?) :confuse:
  • kitykity Posts: 2
    Mine is a 140-2500, 2006 Sprinter - similar problem: sounds like I'm going over rumble strips in roadway, only there are no rumble strips! Solution: drive faster, harder? I hardly think that is a safe recommendation from any mechanic. What's the real problem? What's the real solution? Anyone?
  • txx1txx1 Posts: 3
    Go to the sprintervan list on yahoo and do a search for "rumble strip noise." There's an individual by the name of florin (do a search) that just did a recent increase in the ATF level and it fixes the problem. He even included a pdf file for the dipstick information.

    According to him, and some others as well, the 5speed tranny is very picky on the correct level of ATF. Sometimes it comes underfilled and exhibits the rumble strip noise or transmission vibration.

    Why are you changing to 16" wheels? Depending on what tires you put on the 16" wheels your speedometer and odometer may read falsely high, falsely low or essentially the same as with the stock wheels and tires. It depends on the effective outside diameter at the tread--the revolutions per mile. If you do this, the dealer may be able to reset the speedometer/odometer to read the correct speed with the new size tires.

    There are tire calculator programs on the net, but it is easy to do it yourself.

    For example, my Dodge Spirit has 195/70-14 tires on 14" wheels.

    Dia at tread = (195mm)(0.70)(1in/25.4mm)(2) + 14in = 24.75 inches

    The tire sticker also lists 205/60-15 tires which would of course require new 15" wheels

    Dia at tread = (205)(0.60)(1/25.4)(2) + 15 = 24.69 inches.

    The diameters at the tread are equal and the speedometer/odometer will read the same. The 205/60-15s give superior handling, but at the expense of slightly lower mpg due to increased rolling resistance of performance (sticky) tires. The 10 mm narrower stock tires give adequate handling for me, and I value fuel economy highly, so I've just stayed with the original tires/wheels which came on this 1991 base model Dodge Spirit 2.5L 5-spd, 34 mpg at 70 mph with the a/c on.

    If you change to a tire/wheel combination which is significantly larger at the tread then you would be increasing the effective gear ratio throughout the gear range and this should save fuel when cruising at light accelerator pressure, but you will not have as good acceleration. If you habitually have the van relatively lightly loaded and don't use it in hilly terrain, then this may be the right thing to do. But if you use an unapproved tire size, then you will have substituted your own judgment for that of the MB engineers as to what is the best tire for the Sprinter. I wouldn't do this lightly.

    As mentioned, the gear ratio will be different with different tires. Sure, you may save a few bucks on fuel, but how long until you need engine work due to the strain on the engine?

    Hi Jim,
    I'm changing my rims and tires for several reasons: I can't stand those Goodyear Cargo Vectors that came on the van; they have ultra-stiff sidewalls and ride too rough. My (118", low-roof, passenger model) van is almost always lightly loaded. Also, my speedometer & odometer are registering high as is, so the larger-circumference tires will correct some of this.
    (Why does DC do this? My cynical side tells me that they save millions in warranty work by having warranties expire sooner. My wife's Honda CRV came with a high-registering odometer also (we had it checked, and it was almost 8% high), and when I took it into the dealer for recalibrating they said they couldn't do it, and besides, 10% leeway is the legal parameter. So apparently, manufacturers are turning out cars with high-registering speedometers and odometers on purpose. The service advisor told me that that's so I wouldn't get a surprise speeding ticket. Riiiight.)
    As far as acceleration, the van has plenty of low-end power, and I do a lot of highway cruising. And I want to go to not only taller but wider rims so I can put on wider tires to improve the vehicle's stability in cornering and crosswinds. (It's already surprisingly good, though.) Yes, I know that the wider tires might lower the MPG somewhat, depending on the tire type.
    And lastly, I don't like the looks of the stock steel wheels. I've looked at a lot of rims, but I'll probably just end up going with the OEM painted alloy ones that come on some 3500s and are available at dealers or I'm not into fancy. I don't like the looks of the Borbets, I understand the AT Italias have been discontinued, and I can't afford the 18" G-Wagens.
    BTW, as of my second tankful, my MPG increased to 24.79, so it's breaking in, apparently.
    My conundrum was that the new larger-circumference tires will lower the odometer registry, thereby offsetting measured increase in highway MPG I might realize.
    But that's only measurement; my real-world highway MPG will increase, I think.
    Thanks for your input.

    Thanks for the tire calculator; that's real handy. As far as engine strain, my tire circumference won't be much larger, if any, than some of the optional tires that come on Sprinters, so I think I'll be okay. Mine is a low-roof, 118" passenger model with rear seat removed, and my cargo, when I carry any, doesn't weigh much at all. Thanks again.

    Be very careful changing tire sizes on the Sprinter. They use LT metric tires or the European equivalent. It is very important that you get sufficient load capacity. Overloaded tire failures can sometimes have tragic results.

    So it's best to work with a tire shop who knows what they are doing.
  • jim314jim314 Posts: 491
    Interesting about the 10 % variance allowed on the accuracy of the odometer and speedometer. However, I would think that a consistent bias of the calibration would be uncovered by either the government or by auto journalists.

    What are the sizes of the original tire/wheel combination and the proposed new ones? This vehicle has dynamic stability and traction control. It's at least theoretically possible that the DSTC is engineered to work best with the stock tires.
  • kenbob88kenbob88 Posts: 21
    I know; it seems unbelievable that such extreme variance could be allowed, but that's what the Honda service advisor told me.
    And yeah, we would HOPE that a consistent bias by auto manufacturers would be exposed, but there's little government oversight going on in any area these days (mine safety, for example), and investigative journalists are a vanishing breed; bloggers seem to do all the heavy lifting.
    My existing stock tires are 27.4" dia. and the 245/70 16s would be about 29.5". I hope they will fit without having to modify the wheel wells and mudflaps as some owners have had to do when changing wheels/tires.
    Thanks for raising the issue of the DSTC; if anyone has any further insight, I would appreciate it.
  • jim314jim314 Posts: 491
    Wow! An increase of 2.1 inch in diameter would nominally raise the entire vehicle 1 inch higher. Of course, if you use softer tires the true increase in radius may not be a full 1 inch.

    I do not think there could be any reasonably expected benefit which would justify this, first from the cost, but second and mainly you would be raising an already high and narrow vehicle significantly higher. This could reduce stability and increase the effect of cross winds.

    Raising the vehicle could increase the air resistance and negate the fuel saving effect of higher gearing. Then there is the potential for interference of the tires with the wheel wells.

    Well, took my Sprinter to the dealer this A.M. and sure enough, the air flow sensor was bad. What a difference this made. The van has more power, runs quieter and smoother. Even the shifting pattern seems to have changed. I was also told that the rust spots on the white paint were caused by brake dust and would rub out with wax. We'll see when the weather breaks. Thanks to all for your replies. :)

    You hit it right on the button. I was in and out of the dealership in an hour. Truck runs great again. Thanks for the info.
