Question about 2004 Chrysler Pacifica

2 Answers

My speedometer registers about 40 mph over actual speed. I have standard tires, no transmission work has been done, did have new rotors put on last week, but it worked fine for several days after that. Started up this morning and the speedometer went crazy. Any suggestions?

Check the wires to your wheel speed sensors. Sounds like possibly the connectors were not put on completely tight when doing your brakes...if they had to remove them. If not, you have a problem with one or all of those sensors. I believe you have 2.

It does sound like it is related to your speed sensors. They are located at the close to the rotors. If a shop performed the service, be sure to have them take care of the repair, as it sounds like their error.

Speedometer off


Over the years I have had many complaints of the speedometer being inaccurate, few times has it actually been the case, about 5% I would say. You can have the speeds checked for accuracy by any dealer using a known good vehicle speedometer pace car, done the test dozens of times. Normal speedo accuracy is plus or minus 3 MPH.

I have a 92 GMC stepside and its lifted about 4.5 inches. I think its making my speedomiter be off. It says im going 50mph when i feel like im going 20mph. It also has a rebuilt motor and transmision....


If you have got taller tires on then what it came with from the factory it will definitly throw the speedometer off.You will need it to be recalibrated for a different speedometer gear put in the transmission.This will correct the odometer

Well i'm going 60 mph but my speedometer read 70 plus for avery mile that i travel the meter read 1 1/3 so my car is gona hit 1k if i still friving like that?


In most cars especially those older models, the speed sensor for the speedometer is located in the transmission. Check for physical wear on the cable that leads from the transmission to the back of the dashboard. If you have increased the size of the tires dramatically, the actual car speed would be slower then the speedometer. Either the components responsible for measuring speed (speed cable, dashboard, speedsensor) is damaged or tire size or transmission parts or the transmission itself was replaced.

Nissan Maxima speedometer reads 20 mph but actual speed is 40-50 mph, is my transmission going bad?


NO, IT'S NOT THE TRANSMISSION! SOUNDS LIKE A SPEEDOMETER PROBLEM! THAT WOULD BE ONE OF THREE THINGS! EITHER THE SPEEDOMETER, THE CABLE, OR THE SPEED SENSOR! THE SPEED SENSOR WILL USUALLY GIVE YOU A P0500 CODE ON AN OBD-II CODE READER! THE SPEED SENSOR IS ELECTRONIC SPEED CONTROL LOCATED ON THE TRANSMISSION! SOME HAVE A SPEEDOMETER CABLE HOOKED TO THEM, AND SOME JUST HAVE A 2 WIRE PLUG THAT HOOKS TO IT!

you might need a new speedo cable but if its a sensor you could need a new sensor and that might not be cheap.
