Replacement of your speed sensor is your only option here,assuming connections have been checked and are good, idont know if you have kids but sometimes they get disconnected to hide extra miles put on the vehicle

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 ?????? .

1992 Subaru legacy wagon will not shift up from first gear. it is an AT.


run the fault but all you describe is operated from the VSS sensor ( vehicle speed sensor)
it tells the cruise control the vehicle speed , tells the TCM the vehicle speed so that ratios can be changed, activates the speedo,and will report with a check engine light to report a transmission problem
run the fault codes first

What will make my truck shut off while driving. The truck runs well, will shut off without indication. I can start it back in neutral or park, sometimes it will turn over once or twice then start.


its a brake failure system problem

those codes say
hey this truck doesn't have a working abs brake system
STOP this truck

abs module could be a leaky or failed pressure valve
wheel sensors ..dirty or insulation cracked

no rear speed signal is generated as abs system fails

P0440-Evap Emissions. code of is a different issue

I have a1999 cougar the speed on stop working now the transmission will not shift in less you manual shift your self what could be the problem


The speedometer stopped working ? is this what you meant ? You probably have a bad VSS - vehicle speed sensor . The VSS is an input to the PCM - engine computer , besides being a signal for the speedometer it is used for shift control and other thing's .
Vehicle Speed Sensor The vehicle speed sensor (VSS) (Figure 43) is a variable reluctance or Hall-effect 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. You could possibly have a DTC stored in the PCM.
P0500 - Vehicle Speed Sensor (VSS) Malfunction Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. Vehicle speed data is received from either the vehicle speed sensor (VSS), transfer case speed sensor (TCSS), anti-lock brake system (ABS) control module, generic electronic module (GEM), or central timer module (CTM). If the engine rpm is above the torque converter stall speed (automatic transmission) and engine load is high, it can be inferred that the vehicle must be moving. If there is insufficient vehicle speed data input, a malfunction is indicated and a DTC is set. On most vehicle applications the malfunction indicator lamp (MIL) will be triggered when this DTC is set.
  • Open in VSS+/VSS- harness circuit.
  • Open in TCSS signal or TCSS signal return harness circuit.
  • Short to GND in VSS harness circuit.
  • Short to GND in TCSS harness circuit.
  • Short to PWR in VSS harness circuit.
  • Short to PWR in TCSS harness circuit.
  • Open or short in the vehicle speed circuit(s) (VSC) between the PCM and appropriate control module.
  • Damaged VSS or TCSS.
  • Damaged wheel speed sensors.
  • Damaged wheel speed sensor harness circuits.
  • Damage in module(s) connected to VSC/VSS circuit.
  • Damage drive mechanism for VSS or TCSS.
Diagnostic Aids: - Monitor VSS PID while driving vehicle. This DTC is set when the PCM detects a sudden loss of VSS signal over a period of time. If vehicle speed data is lost, check source of where vehicle speed signal originates. Note TCSS does not have a PID, circuitry frequency must be checked for sudden loss of sensor signal. P0501 - Vehicle Speed Sensor (VSS) Range/ Performance Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. This DTC is set the same way as P0500, however the malfunction indicator lamp (MIL) is not triggered.
  • Refer to possible causes for P0500.
Refer to diagnostic aids for P0500.

Suddenly the ABS light came on. Fluid OK, sensors not broken. Is there a way to check the speed sensors?


The abs light,has to do with the brakes,if the sensors have been checked then the brake liners most likely need attention,if the vehicle does not stop correctly the abs light will come on.

ABS Fault indicator ? Is this an issue or just another money scheme ? Brakes seem to be working fine, truck has 155K on her.


The way the Brakes work on your Colorado, if there is an issue with your ABS, the brakes will still work. You may just not the have ABS brakes active. Most common cause of the ABS indicator is a faulty sensor to one of the 4 wheel. the common ones are the front wheels. Inspect the ABS sensor lead wire which should be along the A-arms to the ABS sensor on the inside wheel hub. Spray brake parts cleaner to the sensor and speed ring to ensure there clean and free of dirt that may be hindering the sensor to read the speed ring on the hub. Look at the condition of the lead wire and inspect for corrosion or any other type of damage. Most of the time a good spray of Brake parts cleaner will fix the problem. If there is an Auto Zone around your area, buy the brake parts cleaner there and have them scan the truck for the DTC codes which would indicate that it is the ABS sensor and not the ABS module, which will be costly and your most likely run it the way it is without ABS due to cost of replacing the module. Good luck friend.

Transmission codes:


I WOULD TRY REPLACING THE INPUT SPEED SENSOR..A DEFECTIVE SPEED SENSOR CAN CAUSE ALL OF THESE FAULTS..IT IS LOCATED IN FRONT OF TRANS ABOVE SOLENOID PACK..IT IS THE ONE CLOSEST TO THE ENGINE..IT SCREWS INTO TO TRANSMISSION..A 1 INCH SOCKET FITS IT..ALSO CHECK WIRING TO BOTH SPEED SENSORS..A SENSOR IS ABOUT 35 BUCKS,AVAILABLE AT YOUR LOCAL DODGE DEALER..GET A NEW ONE AND YOU'LL SEE WHAT IT LOOKS LIKE..FAIRLY COMMON PROBLEM..HAVE REPLACED LOTS OF THEM

Problem with my cruise control and ABS light on 03 Explorer


Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • Anti-lock brake control module (ECU)
  • rear wheel speed sensor
  • rear wheel speed sensor rings
  • yellow anti-lock brake warning indicator
The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:
  • active brake booster with integral solenoid
  • brake booster release switch
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • stability assist module (ECU)
  • stability assist event indicator
  • lateral accelerometer
  • longitudinal accelerometer (4x4)
  • rear wheel speed sensors
  • rear wheel speed sensor rings
  • steering wheel position sensor
  • yaw rate sensor
  • yellow anti-lock brake warning indicator
  • brake pressure transducer
  • traction control switch
---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation
  1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
    Cut the carpeting along the perforations.
  1. Disconnect the electrical connector.
  1. Remove the nuts and remove the accelerometer.

Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info
  • A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
  • Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.
  • The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.
  • During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.
  • Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.
  • Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.
  • Warning Lamp Indicator
    The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
    The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

    -----------------------------------------
    Please report back, I am curious if that is what it is. Good luck
