Hopefully your crank sensor is not located on gearbox as you placed it in your post! VOLVO puts their VSS on the inboard side of an output shaft, usually. You should be looking at the axles, and the holes in the transaxle they extend out of... There will be a sensor reading the inner end of one of these output shafts (axles.) This is your VSS. It operates independently of your ABS, but its accuracy is vital to the ABS's proper function. Its reading is used for many things in the car, not the least of which is speedometer readout. Hope this helps, let me know if you don't see it, I'll get you a more exact location if need be, but if you look carefully, you'll find it. It's reading the speed of one of those axles, but not at the wheel, at the transaxle, get it???

2000 GMC Jimmy 4×4 The ABS light is on, the speed odometer does not work, and it does shift out of 1st gear, if I manually put it into second gear then it will shift fine, it has a changed VSS


Did you have it check for DTC'S - diagnostic trouble codes ?
Speedometer
The speedometer is an analog gauge that is located in the instrument cluster. The PCM/VCM receives an analog input from the vehicle speed sensor and converts it to a digital signal containing 4,000 pulses per mile (PPM) for the instrument cluster.
The PCM/VCM sends this digital output (4,000 PPM) to the instrument cluster on a designated circuit. These pulses can be measured in Hertz (Hz) using a digital multimeter (DMM) on the AC scale. The PCM/VCM calibration is matched to the final drive and tire size of each vehicle. If the final drive or tire size is changed for any reason, the PCM/VCM must be updated in order to match the new final drive or tire size. If not, the signal will not be accurate for proper speedometer/odometer operation. An incorrect signal can affect the antilock brakes and the cruise control systems.
The speedometer system consists of the instrument cluster, vehicle speed sensor (VSS), PCM/VCM and related wiring. The VSS is a permanent magnet signal generator that sends an analog signal proportional to the propeller shaft speed to the PCM/VCM. The VSS mounts to the transmission tailshaft extension housing on 2-wheel drive (2WD) models and the transfer case output shaft housing on 4-wheel drive (4WD) models.
Repairs to the instrument cluster can only be performed by an authorized instrument cluster service center. DTC P0502 Vehicle Speed Sensor (VSS) Circuit Low Input and DTC P0503 Vehicle Speed Sensor (VSS) Circuit Intermittent in Automatic Transmission - 4L60-E
- DTC P0500 Vehicle Speed Sensor (VSS) Circuit in Engine Controls - 4.3L Important: If the instrument cluster is completely inoperative, refer to Instrument Cluster Inoperative .
Install a scan tool.
Raise the vehicles drive wheels. Refer to Lifting and Jacking the Vehicle in General Information.
Start the engine.
Place the transmission into drive for automatic transmission and third gear for manual transmission.
Compare the displayed vehicle speed on the Instrument Cluster with the monitored speed on the scan tool.
Does the vehicles speedometer and the scan tool both display 0 km/h (0 mph)? You really need a Factory scan tool or equivalent to check this . The VSS is an input to the PCM/VCM . engine computer . You can test with a DVOM - digital volt ohm meter , for signal to engine computer .
I know most people don't like hearing this , but I suggest you take it to a ASE certified repair facility .

Asb light is on & speedometer quit working


does car drive? (ill presume no)

you mean ABS, antilock braking system.

the Check engine light is not on , running, if is scan it.



of car runs perfect.

but ABS is on, read operators guide, it say take it to service.

if you open the FSM it says what to test, all tools you dont have

but most ABS fails are BRAKES bad or dirty sensors , or got hit sensors (wheel sensors, see those tone rings???)

fix the brakes first, normal brakes.

the speedompeter., that is hopefully just a bad fuse.

if not a fuse post back there are other tests

here is just one:

1: attach, scan tool does MPH at VSS sensor read rigth at all speeds.

yes, then the speedo is bad.

no, then the VSS is bad. and ECU will puke lots of DTC errors for that.

Scan the ECU/PCM for errors.

Speed sensor


there are many on some cars 5 or more.
what engine,? what transmission?
1: crank shaft rpm CKP sensor.
2: VSS 1 tranny front sensor Automatics.
3: vss 2 tranny rear. """
4:speedo back up VSS to vss 1.
5: cam speed, or Angle.

why not say the symptoms and why VSS is on your mind.
did you use a scan tool, if not why not?
the scan tool will tell you which sensors readings are wrong
and just because one is, dont mean the sensor is bad.
the PCM /ECU never knows what is bad, ONLY what tests
failed (called monitors) and its the job of the technician
to do the FSM tests. and find TRUE CAUSE.


SCAN it and stop guessing, or go broke.

Where is my speed sensor located?


Hi.

The vehicle speed sensor or VSS is located on top of the transmission, on the output shaft. This sensor provides input to the speedometer on instrument cluster. There are also 4 wheel speed sensors (one on each wheel). Their primary function is to detect wheel speed to control ABS.

Below a picture of the VSS sensor:

Trac light& abs light stay on need to know how to get them off


Have the ABS scanned and it will tell ya which VSS vehicle speed sensor is not working, once you change that particular wheel hub then those light will go away. Good luck.

ABS stays on a 2001 GMC Jimmy


This is a common issue, and is pretty easy to fix. There are ABS sensors on the wheels, and you have a bad one. Usually the wires become corroded, and are easy to spot. The unit is on the back side of the wheel assembly.

Why does my traction active & service traction system lights keep coming on?


most likely a bad wheel speed sensor

have a technician drive it with a scan tool and monitor all VSS

I suspect one if off
You can also confirm this buy trying to lock up the brakes in a safe location

if ABS activates early/late or not at all this too is a sign of a VSS concern

My 1996 S-10 Blazer will not shift sometimes and the ABS light comes on. This problem goes away after I drive it for awhile. The code I get is P0502 (vehicle speed sensor low imput). Would a bad speed...


A faulty VSS (Vehicle Speed Sensor) or related wiring can cause both of your problems, trans and ABS. If the computer doesn't know the vehicle is moving, then it won't shift the trans. If the ABS controller sees wheel speed, but not vehicle speed, it will turn on the ABS light. The VSS is located in the rear transfer case housing. But remember, it may be the VSS, related wiring, a faulty speedo buffer (usually located in the dashboard), ECM, or even the reluctor on the transfer case output shaft. You may want to have a shop scan "data stream", or even have them diagnose the problem.

Abs require service


The code is for the Vehicle Speed Signal (VSS). The VSS is produced by the ABS electronic control unit by averaging wheel speed sensor inputs and sending a digital signal via CAN bus to other modules that use the VSS. To test the ABS, a Volvo-compatible scan tool is necessary. If one is not available, the car should be sent to a Volvo dealer for ABS diagnosis. I can tell you however that most of the cars are fixed by replacing the ABS Control Module.
