Feb 8, 2010
Noticed today that I can have the multi-function display -- AKA MFD -- show the speed. Is it more accurate than the "analog" speedometer?

Golf IV / Jetta IV :: Speedometer Reading Accurate Only Till Around 45 Mph
My speedometer reads accurate only till around 45 mph. The needle begins to float around gently, and the faster I go, the more discrepancy it reads. It may hang a while, floating around 60 and the speedometer app on my phone says I'm going 74.
The speed sensors were replaced for another issue a year and a half ago. The dealership initially wanted me to put a new transmission in it for $3800 after they said the trans was slipping past 45. Then they said something instead about a valve plate (could be wrong vernacular) for $1000 instead of an entire transmission.
When I finally told them that my cruise control is completely erratic, trying to track the needle movements with upshifts and downshifts, they said it's $200 in parts for the drive gears and that they were made with plastic that can wear out.
So I said I would sit on it, since the ideas about the issue seem to vary greatly, and my father set me up to go to a transmission shop to have the car checked out. They had it for two days and changed the fluid out but we can't fix your speedometer issue... take it to the speedometer shop, but btw we think your transmission is fine.
Now, do I take it back to the dealer for the drive gears, or do I take it to another specialist? I have seen people say all it needed were the drive gears replaced and a new sensor. My odometer seems to still be working. There is no issue with my gas gauge.
Ford Super Duty (1999-2016) :: Speedometer Is Accurate To Within 1 Mph Or So
I've got a 99 F-250 7.3 with the 6 speed manual. My speedometer is accurate to within 1 mph or so. However when compared to a GPS unit, my odometer is off by about 50%...meaning it registers approximately 1 mile for every 2 traveled.
I was under the impression the mechanism that results in the speed being displayed is the same one driving the odometer and therefore if one was off, the other would be (conversely, if the speedo is accurate, so would be the ODO). How do I resolve this issue?
Ford Super Duty (1999-2016) :: Got 20" Rims - Odometer Or Speedometer Accurate?

Not that it matters but its a 99 F350 CC LB 3.73 axle ratio
Ford Super Duty (1999-2016) :: 2013 - Speedometer Give Accurate Reading?
The 19.5" wheels are not an option on the 2013 F-450, unless you order a Chassis Cab. I'm certain many have made this change. My question is can the dealership make the necessary changes so the speedometer correctly measures the vehicle speed?

I have previously noted that the Prius display of speed is about 1 mph higher than actual as measured by GPS and those ubiquitous street radar signs. However, the OBD-2 display using the Garmin Mechanic exactly agrees with the GPS. I wonder how this relates to the well known display mpg being 3mpg or so higher than actual measured by tank fill-ups.
View 5 RepliesGolf VI R :: P3Cars Gauge With Analog Boost Noise?
I purchased a P3Cars gauge and an analog boost sensor with an ECS boost tap. I seem to be getting some fluttering noise at higher boost (greater than about 15 psi).
It was my understanding that digital boost gauges didn't buzz, so I thought I high have some movement of the boost sensor, hose, or the interface box for the gauge. I've got these pretty well padded and fixed with zip ties.
Do I need to get an inline restrictor (cotton swab, filter or otherwise) to eliminate this fluttering noise?
Golf V R32 :: MIL With 3 Codes But Can't Find Accurate DTC Lookup
Got a MIL today, and the 3 codes I found are P0047, P0204, and C0204. Only reference to P0047 is for boost control solenoid, that can't be right. Is there a good place to look up our specific car's codes?
Also, whats the difference between Current DTCs and Pending DTCs? The reader I'm using shows these codes under pending.
Golf IV / Jetta IV :: MFA And Climatronic Panel Don't Give Accurate Reading
My display on the MFA and Climatronic panel is really wrong (-44C now). I was taking a look at the sensor in the front left grille but the only thing that's changing into the readings with my Vag-Com is the outside temperature sensor but not the displayed temperature.
I didn't find any other sensor on my car. Nothing into the rain tray...
Tiguan :: Speedometer Reads Less Than Actual Speed
I timed my Tiguan for ten miles with the cruise control at 60mph on the way home tonight. This is the first car I've had where the speedometer reads less than actual speed. Average speed was 62.36mph. It varied between 60 and 65 on a mile by mile basis, but I can't put my finger on what caused the variation. The speed limit is 65 on that stretch, and there are a couple hills, but I was lucky and avoided slowpokes that would have taken me out of cruise.

Lexus SC430 :: Speed Needle Doesn't Work In Speedometer
In my current speedometer the speed needle doesn't work i did everything and changed all sensors and checked all related issues and all is fine turned out the issue was with the speed gauge it self. So i bought my self a used speedometer.
Now my question is, how to dismantle the speedometer cause I want to take out the speed gauge from my old one a replace it with the new one i know its much easy to change the whole thing but I don't want to play with the mileage I have on my car.

I'm curious why the speedometer on the Santa fe goes to 140mph when the speed limiter will only let you go to 105mph. I have done ECU upgrades with Nissan's and ECU "reflashes" with Toyotas in the past. How to eliminate the 105 PMH speed limiter?

I have a 2007 Toyota Camry Hybrid that is having a speedometer problem. The speedometer registers 3 MPH more than my actual speed regardless what speed I am traveling. For example, if I am going 25 MPH, my speedometer will read 28 MPH; if I am traveling at 60 MPH my speedometer will read 63 MPH. I took my car to the dealership and they replicated the issue, but said that it is operating within ?normal? range. They admitted that they do not know how to fix the problem. I did not need to worry for it is operating within normal range. I have never had this problem with any other car, including my previous Toyota Camry.
View 2 RepliesFord Ranger / B-Series :: Speedometer Will Reverse Despite Of Increasing Speed When Gets Over 75 MPH
1999 (built late 1998) Ranger 2.5 stick 2wd single cab. If I get much over 75 MPH the speedometer will reverse direction despite increasing speed. If I then let off the throttle completely, the speedo will jump right back up and indicate the correct speed. Continued operation without letting off the throttle to let the speedo recover will trip the ABS fault light, probably due to the erratic signal.
Disconnecting RABS module has no effect on symptoms. Speed sensor in the rear axle has been replaced already (by me) and the new unit ohm'd out good. Wiring between GEM and sensor checks out as well, good continuity (< 1 ohm) and no shorts to chassis ground. I wish I had an o'scope to take a look at the waveform, but I don't at the moment. It is on my future tool purchase list.
S-10 :: Blazer - Speedometer Is Jumping Around Sporadically - Tranny Slips At Highway Speed
So I'm having some fun issues with my S10 Blazer right now.
1992 S10 Blazer 4x4 4.3L TBI, 4-speed auto (not electronic)
ABS Codes- 41, 42, 46, 51, 52, 65, 67, 68
The speedometer is jumping around sporadically.
Gas mileage has dropped astoundingly. Tank has gotten me 80 miles!!!! Poorest MPG ever!!
Also, may be related, the tranny has shifted properly for awhile. Slips from 4th to 3rd when letting off the gas at highway speed, and won't detente shift 4th to 3rd even with the gas completely floored. I had the tranny rebuilt in November and had the detente cable replaced a couple of weeks ago. I'm going to make sure it was adjusted correctly today by using the shop manual method: shift the cable back and ratchet forward with throttle or gas pedal.
As far as the ABS and speedometer go, I'm going to test what I can with the vehicle speed sensor (VSS) and the DRAC module today. With my WinALDL scan tool, I found it is definitely not a speedometer issue because the speed coming from the computer is fluctuating as well.
There is a test in the shop manual to do, but are there any other tests for the VSS or DRAC module? Reason here is because I replaced the VSS after the tranny rebuild in November. So either the DRAC module is acting up or something in the transfer case is screwed.
Camry :: 2003 LE V6 - Changing Wheel Speed For Correct Speedometer Reading
I have a 2003 Toyota Camry LE V6, It has 15 inch stock wheels on it
If I go to a larger wheel, is it possible to change the wheel speed so that the speedometer reads correct? If I have read correct, the stock offset is +45 and the lug pattern is 5x114.3 and a 6.5inch wheel?
Prius (Gen 2) :: Warning Lights And Speedometer Flickers - Replaced Speed Sensors
I bought two new factory fresh speed sensors to replace the ones. So, after work tonight I get the car up on jack stands and replace both sensors in about 45 minutes. Get it off the jack stands, torque down the rims and reset the dash lights. Nice clean dash display with no warning lights.
I drive it down the street, nice speedometer display and then, after about 100 yards, the warning lights come on and the speedometer flickers from 22mph to 2 then 10 then 1 then zero. I drive it back home, check the sensors and the connections, reset the lights again, drive it down the street and, same story.
Impala - Chevrolet :: 2004 - Speedometer Will Shift 10 Or 20 Mph Faster Than Actual Speed
Got a 2004 Chevy Impala with 99K miles. Speedometer seems to be acting sporadically often. Sometimes, it will shift 10 or 20 mph "faster" than actual speed then, sometimes, it goes to the "maximum" speed on the dial and just stays there with the car on or off. Then a few days later, starts working normal again.
