The only thing you can do is buy another sensor. They are less than $100 new. The speed sensor has had a few part revisions too.

I recently sold my wife's Buell Blast to a nice young girl who called to say the speedometer has stopped working.  I did the speedo diagnostic and get a 02set code which will clear if the reset is held in but comes back immediately when you let go of the reset.  I removed the speed sensor and cleaned it but it still doesn't work and I realized that while the odometer does display accurate numbers and toggles between odometer and trip readings the mileage does not advance when the bike is ridden.  Any imput you may give will be appreciated.  As an aside I have a 92 RS1200.  Parts are hard if not impossible to find. Last year my rear caliper died and after much research found a comparable replacement.  Anyone who needs help with pre-Harley Buells can write me at any time.The only thing you can do about the speed sensor is buy a new one.  I got one this year for my 03 Firebolt as it was bad too and my speedo and tach didn't work when I first bought the bike. ,,,

My 2005 Cadillac Deville speedometer goes to zero and transmission seems get stuck and car will not go over 15-20 mph with high engine rpms. Unless I mash on the petal to make it skip gears. #help


problems with speed sensor for transmission. Computer uses a speed signal to shift transmission through the gears. Without speed input, the computer doesn't know when to shift the transmission. Either the speed sensor is bad or wiring from the ECM to the speed sensor is bad. Usually 2 wires lead to the sensor. The sensor generates a AC voltage signal with higher speeds generating more voltage and frequency. The ECM (computer), looks at the signal to see how fast the vehicle is traveling.

Code 22 flashed up and motor wont turn


Precor Error Code 22 Error Code: 22 Manufacturer: Precor
Model: All Models
Error Description: Error 22, No Motor Pulses at Start Up - Error indicates that the display has sent a command for the drive motor to start, however, the speed sensor has not returned the signal acknowledging that the drive motor has started. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Badly worn drive motor brushes.
  3. Incorrect gap between the speed sensor and the speed sensor target.
  4. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  5. Inoperative speed sensor.
  6. Faulty lower PCA.
  7. Faulty interconnect cable between upper and lower PCA.
  8. Faulty upper PCA.
Recommended Action:
  1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
  2. Bady worn drive motor brushes cannot make proper contact with the motor commutator, therefore the drive motor will not start when voltage is applied. Inspect and replace drive motor brushes if necessary.
  3. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
  4. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
  5. An inoperative speed sensor will allow the drive motor to start and run briefly before the error appears. If able to access the speed sensor wiring, measure the DC voltage between the speed sensor leads. Two of the leads will always read about 5 VDC. Two will toggle between 0 and 5 VDC as you slowly turn the speed sensor target. If both measurements are not seen, the speed sensor needs replaced. Some units have the speed sensor mounted on the lower PCA and the lower PCA needs replaced.
  6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
  7. Determine if the interconnect cable is bad by swapping with a know good cable.
  8. Determine if the upper PCA is bad by swapping with a know good upper PCA.

Speedometor is going 50mph in a 35mph zone and 90to100 in a 55mph in my 2004buick lesabre .help me thank you


your speed sensor is bad the housing for the sensor and sensor tend to go bad after a while(old car) but have you triend with another cluster, instrument panel? what you describe seems more likely to be the speed sensor at the transmission.

91 cherokee shifts fine at fist but after a minute or so it wont shift out of first gear. changed the output speed sensor but no change


Sounds like a bad out speed sensor.Are you sure you replaced the correct sensor?This trans(AW340)Has an output speed sensor and a vehicle speed sensor.The output speed sensor is located on the side of tail housing just next to where it bolts to transmission case.The vehicle speed sensor will be about midway of the tail housing or on the transfer case tail housing on the 4x4 models.It may be a good idea to have a tranny shop you trust run a diagnostic and see if you are getting output sensor signal to TCM( transmission control module behind glove box)and take a look at TPS (throttle position sensor)signal when it is hot to make sure you replace the correct part.I have seen bad TPS sensors on these jeep not affect engine drivability because the sensor is really two(one for trans and one for engine)thus the two plugs on the TPS sensor for the automatic Cherokee.Good Luck and let me know if I can help.

Transmission does not upshift. Shifts from park to reverse to neutral to drive but does not upshift from 1st gear. 117000 miles on the odometer HELP!!!


Sounds like one of the speed sensors are bad. It has an input speed sensor and an output shaft speed sensor. You need to have the TCM scanned for codes to see if one of them is bad.

My Precor 9.31 made a loud "click" sound and turned off while I was walking on it. Error 22. What does this mean?


Error 22 indicates that the drive motor (running belt) has been instructed to start, by either manual or program control, and the monitoring system has not received any response from the speed sensing system indicating that the drive motor has started.
1. Drive motor brushes are bad or the lower PCA is bad.

Can you tell me what Err22 is? Thanks!


Description
Error 22 indicates that the drive motor (running belt) has been instructed to start, by either
manual or program control, and the monitoring system has not received any response from the
speed sensing system indicating that the drive motor has started.
Possible Causes
1. The treadmill utilizes an optical (infrared) speed sensor and the line of sight between the
speed sensor and the speed sensor target is obstructed.
2. Drive motor brushes are bad.
3. The speed sensor position relative to the speed sensor target is incorrect.
4. The speed sensor potentiometer adjustment is incorrect (when equipped).
5. The speed sensor is inoperative.
6. The lower PCA is bad.
7. The lower PCA to upper PCA interconnect cable is bad.
8. The upper PCA is bad
Possible Remedies
1. Carefully, vacuum out the drive motor compartment with a static safe vacuum cleaner. Pay
special attention to the area between the speed sensor and speed sensor target.
2. If the motor brushes do not make sufficient contact with the motor commutator, the drive
motor will not start when drive voltage is applied. Replace both drive motor brushes.
3. Adjust the speed sensor position so that the space between the speed sensor and the speed
sensor target is 3/16 inch and so that the speed sensor photo eye is aimed at the larger
portion of the targets wedge shaped section. On hall effect speed sensors (magnetic sensor)
the space between the end of the speed sensor and the flywheel tooth should be 3/16 inch.
4. Locate the speed sensor potentiometer on the lower PCA. Set the speed sensor
potentiometer at mid-range. Start the treadmill and increase the speed to 6 mile per hour.
Carefully adjust the speed sensor potentiometer to the point where the treadmill is operating
the smoothest. Increase the treadmills speed to full speed at repeat the previous adjustment.
These two adjustments are typically small and are usually only a matter of fine tuning.
5. If the speed sensor in inoperative the drive motor will start and run briefly before the error 21
occurs. If it is possible to access the speed sensor wiring, measure the D.C. voltage between
the speed sensor leads Two of the leads will constantly read approximately 5 Vdc. Two of the
leads will toggle between 0 Vdc. and 5 Vdc. as you slowly rotate the speed sensor target. If
you do not see both measurements above, the speed sensor is inoperative and must be
replaced. In some cases the speed sensor is mounted on the lower PCA and the the lower
PCA must be replaced.
6. Substitute a known good lower PCA to determine if the lower PCA is bad.
7. Substitute a known good interconnect cable for the existing cable.
8. Substitute a known good upper PCA to determine if the upper PCA is bad.
