Question about Volkswagen Passat

1 Answer

I have a 2007 Passat 2.0 turbo wagon and the digital speedometer is very far off the actual speed indicated on the analog speedometer, about 45 mph indicated to 70 mph on the analog. Also the display switches to "miles range" from the speedometer at will.

Have you called transmission place? Did they also install it? Ask them if they changed speedometer adapter, and mention the difference in speed.

2007 Saturn Vue while driving, speedometer stops working and trans starts shifting funny


The electronics involved are unique to say the least .
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the body control module (BCM). The engine control module (ECM) calculates the vehicle speed based on the controlled area network (CAN) serial data message indicating the wheel reference speed from the electronic brake control module (EBCM). The ECM sends a CAN serial data message to the BCM indicating the vehicle speed. The BCM sends a class 2 message to the IPC indicating the vehicle speed.
The speedometer defaults to 0 km/h (0 mph) when any of the following occur:
• The EBCM detects a malfunction in the vehicle speed sensor circuit.
• The ECM detects a loss of CAN communications with the EBCM.
• The BCM detects a loss of CAN communications with the ECM.
• The IPC detects a loss of class 2 communications with the BCM.

Is the ABS light lit ? Having the vehicle checked for DTC'S - diagnostic trouble codes would be the best first step to finding the problem . Could be a wheel speed sensor or ?????? .

My speedometer on my 2005 Buick rendezvous starts off on zero and then shoots up to 110 when I am at a complete stop. I have changed the speed sensor module and checked the fuses. What else could it b


What module did you replace ? Was the vehicle transmission shifting OK ? The gauge is controlled by a stepper motor inside the instrument cluster , GM had bad stepper motors 03 to 06 .That is probably your problem .

Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM converts the data from the vehicle speed sensor to a 4,000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4,000 pulses/mile), class 2 message from the ECM/PCM in order to calculate the vehicle speed. If the IPC detects a malfunction in the vehicle speed signal circuit from the ECM/PCM, the IPC uses the class 2 message from the EBCM, indicating the vehicle speed as a backup. If the speedometer reaches (108 mph) the fuel will shut-off, and it will turn back ON when the speedometer is at (106 mph). The speedometer displays either miles or kilometers as requested by the activation of the english/metric button on the driver information center (DIC). The associated indicator (km/h or mph) illuminates.

Where is the speed sensor located on a 2003 buick rendezvous


Why ? speedometer not working ? Does the vehicle shift correctly ? The VSS - vehicle speed sensor is an input to the PCM - engine computer > Speed info is sent from the PCM to the microprocessor in the instrument cluster over the class 2 serial data bus . 2003 - 2006 GM vehicles had bad step motors in the instrument cluster . Step motors control gauge position. The VSS is located on the transmission case Vehicle Speed Sensor (VSS)
Lower right rear of the engine compartment, mounted to the right side of the transaxle.

My 05 Focus speedometer is wacky. All other gauges and systems work fine. The speedometer needle doesn't go to zero when vehicle stops moving.


Sounds like the speedometer is faulty. If the speed sensor were the problem, the odometer would not work correctly, the transmission would not shift correctly, and the check engine light would be on.

It is a 4x4 and I cant find the speed sensor that operates the speedometer. The speedometer sticks at 100mph at a dead stop. It also jumps around between 75 and 80 at random when I am only doing 45 mph.


On our Lincoln, the problem was the Alternator shorting and energizing the ground circuit with Positive juice. Our speedometer and odometer were both affected.

We had miles advancing and 45-50 MPH at a stop. Then inaccurate readings while the car was moving.

Car-stuff.com seems to have the best price for the actual speed sensor which is located in the differential @$11.94.

Please rate my solution and I hope I was helpful.
