SOURCE: my 318 speedometer quit working replaced 2 speed

bad sensors are less common than a faulty ECU.
the OBDII readers they use to trace problems in the car are read through the ecu, not testing the sensor itself, but the reading of it from the euc.

my bmw experiences leads me to the wet eci box.

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that
compartment.

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other
sensors....

all the way to engine failure and worst case burnt and shorted wiring
harness.

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.

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.

Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the powertrain control module (PCM). The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4000 pulses/mile), class 2 message from the PCM in order to calculate the vehicle speed. If the IPC detects a malfunction in the vehicle speed signal circuit from the 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 with 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.

2001 Buick Century Limited speedometer problem, Speedometer not working but odomitor ok. Is there a fuse?


if the odometer is working then the problem is with the speedometer head unit as the odometer gets its information from the same source as the speedometer. you can have the speedometer head checked and fixed if its fixable.

Cannot find tranny oil fill plug for 1995 ford Escort


LEVEL CHECK -manual transmission The vehicle speed sensor (speedometer gear), which is located on the transaxle, serves as the manual transaxle's dipstick.
  1. Park the car on a level surface, turn the engine OFF and apply the parking brake.
  2. Locate the speedometer cable assembly where it enters the transaxle.
  3. Unplug the electrical connection from the vehicle speed sensor (speedometer gear).
  4. Disconnect the speedometer cable from the speed sensor.
  5. Wipe the area around the speed sensor with a clean rag, then loosen the speed sensor retaining bolt.
  6. Gently pry the speed sensor from the transaxle. Fig. 1: Location of the manual transaxle's fluid level marks — 1.8L engine 90981g14.gif
    Fig. 2: Location of the manual transaxle's fluid level marks — 1.9L and 2.0L engines 90981g15.gif

  7. Check the condition of the speed sensor O-ring and replace it if it is damaged.
  8. Check the fluid level on the speed sensor as illustrated.
  9. If the level is low, place a funnel in the speed sensor hole.
  10. Add the specified fluid to the transaxle until the FULL level is reached. Do not overfill the transaxle.
  11. Install the speed sensor and tighten the retaining bolt to 69–104 inch lbs. (8–12 Nm).
  12. Connect the speedometer cable.
  13. Engage the speed sensor electrical connection. Fig. 3: If necessary, add transmission fluid through a funnel into the speed sensor opening 90981g16.gif

Where is the speed sensor located?


The vehicle speed sensor is located below the air cleaner assembly, it is held in with one bolt (I believe 10mm):
  1. Remove the bolt and vehicle speed sensor assembly.
  2. Remove the clip and speedometer driven gear from vehicle speed sensor.
  3. Remove the O-ring from vehicle speed sensor
  4. Coat a new O-ring with ATF and install it to the vehicle speed sensor.
  5. Install the speedometer driven gear to the vehicle speed sensor and clip.
  6. Install the vehicle speed sensor assembly and torque the bolts. Torque: 16 Nm (160 kgf-cm, 12 ft. lbs.)

Speedometer stop working where's the cable?


Your vehicle does not have a traditional speedometer cable. Instead it uses a VSS (Vehicle Speed Sensor) to read speed of the vehicle below is a short test to help you determine if it is the VSS that has failed.

SPEEDOMETER VEHICLE SPEED SENSOR TEST

1. Press and release trip odometer button until function number 6 appears in display window.

2. Turn a front wheel and observe display (pulses are added to number in display. Check impulse signal for speedometer vehicle speed sensor. If 7 pulses are generated per wheel revolution, vehicle speed sensor is okay.

3. If specified number of pulses are not generated, check for open in wiring harness between speed sensor and instrument cluster. Repair wiring harness if necessary. If wiring harness is okay, replace speedometer vehicle speed sensor.

Broken speedometer on 1997 ford explorer


does your cruise control work? If not, check the wiring from the VSS to the speedo cluster. Check VSS connector closely for pin pudhout or corrosion

Sometimes, the VSS siganl is converted by the instrument cluster and sent to the PCM and speedo.

Check engine light on?


Speedometer
The electronic speedometer (17255) receives a speed signal from the vehicle speed sensor (VSS) (9E731). This sensor is also used to sense vehicle speed for the engine management system and to regulate the cruise control when equipped.
----------------------------------------------------------------------------------
Vehicle Speed Sensor The Vehicle Speed Sensor (VSS) (Figure 53) is a variable reluctance or Hall-effect type sensor that generates a waveform with a frequency that is proportional to the speed of the vehicle. If the vehicle is moving at a relatively low velocity, the sensor produces a signal with a low frequency. As the vehicle velocity increases, the sensor generates a signal with a higher frequency. The PCM uses the frequency signal generated by the VSS (and other inputs) to control such parameters as fuel injection, ignition control, transmission/transaxle shift scheduling and torque converter clutch scheduling.
