Check the wire connector at the sensor for the proper voltage and ground. if this is good then replace the transmission speed sensor. if these are not in spec then you will have to back probe the wiring from the sensor back into the wiring harness to find the problem.

SOURCE: 2002 Chevrolet Cavalier wiring harness for radio

absolutely not true. when you take your stock radio out of your vehicle there are clips in it and when u take the clips out and the antenna the radio is free when you buy an aftermarket radio from best buy or wherever it will come with a harness for that specific radio now wherever you buy the radio from they probably have a selection of wiring harness for specific makes and models you just buy that and when u take it to the clips installed in the cavalier it will just snap in then the wires on the radio harness will be color coded to the ones on your new harness good luck!

ps i recommend walmart to buy the harness its about $10 there..

Ask dealer if it has a towing package on it. If it does, you usually just pop fuse in under hood for electric brakes, and harness to adapt into is usually near or at rear bumper. Even if it doesn't have brake wire, you should still be able to install adapter at rear,for lights etc. which is available from dealer or auto supply places, then you may have to run electric brakes separate.

I have a 2000 chevy Cavalier 2.2, the service light track off and ABS lights are on. I replaced the ABS sensor and the lights are still on. How do I fix it.


check fuses and relays --their is more than one sensor-also if the hub is bad replacing the sensor will not fix problem --check and clean all the sensors and harness connections sometimes the debris interferes with the sensor

Brent, Check and clean connections(use electronic contact cleaner), make sure wires are not damaged. Check grounds from EBCM controller. Check links below and don't be afraid to google search for more info.
C 0222 Missing Right Front Speed Signal
C 0226 Missing Left Front Speed Signal
- Faulty Right/Left Front Speed Sensor
- Right/ Left Front Speed Sensor harness is open or shorted
- Right/ Left Front Speed Sensor circuit poor electrical connection
- Faulty EBCM

C 0237 Erratic rear speed signal

You may need a wiring diagram to make sure, but I think the gray wire is reference voltage and it also powers the throttle position sensor. The sensors get power from the engine computer.

How to test front speed sensors that are built into the wheel hub assembly on a 1996 buick riviera using a multimeter


these sensors put out a small amount of AC voltage. If you ohm them they should give some resistance. A lab scope or a graphing meter will show a pattern and sometimes its just not high enough in amplitude. What is your ABS trouble code? the harness for the speed sesnor goes bad, and is very common where the wires flex when you are turning. if the harness is bad, you should be able to get a new one from the Dealer or a AC DELCO parts house.

1995 Chevy 2500 TBI 350 4X4 Long Box - 50K actual. when i started it, i lost the speedometer readings - ABS light came on and stayed on and stays in second hear and doesn't want to shift properly ...


Hi, it is likely your speed sensor has failed or the wiring is broken. The speed sensor is mounted near the rear of the transmission and has 2 wires attached. Check to see if the wires got pulled. If the wires look good, you can test the sensor if you have some jack stands to put under the back wheels. Make sure the transfer case is set to 2WD. Test procedures are pasted below. Please let me know if you have any questions, and thanks for using FixYa.

OPERATION

The vehicle speed sensor is made up of a coil mounted on the transmission and a tooth rotor mounted to the output shaft of the transmission. As each tooth nears the coil, the coil produces an AC voltage pulse. As the vehicle speed increases the number of voltage pulses per second increases.
TESTING

See Figure 1


jturcotte_2211.gif

Fig. Fig. 1: Vehicle Speed Sensor (VSS) and vehicle speed signal buffer wiring diagram

  1. To test the VSS, backprobe the VSS terminals with a high impedance voltmeter (set at the AC voltage scale).
  2. Safely raise and support the entire vehicle using jackstands. Make absolutely sure the vehicle is stable.
  3. Start the vehicle and place it in gear.
  4. Verify that the VSS voltage increases as the drive shaft speed increases.
  5. If the VSS voltage is not as specified the VSS may be faulty.

REMOVAL & INSTALLATION

See Figure 2
  1. Disconnect the negative battery cable.
  2. Disengage the electrical connection.
  3. Unfasten the sensor retainers.
  4. Remove the sensor and gasket or O-ring.

To install:
  1. Install the sensor with a new gasket or O-ring.
  2. Fasten the sensor retainers.
  3. Engage the electrical connections.
  4. Connect the negative battery cable.

Where do i locate speed sensor? 98 cavalier


Speed sensors are usually located on the differential in RWD cars and on the transaxle (which combines the transmission and differential) in FWD cars. The cavalier is a FWD (front wheel drive) car, so the speed sensor is located on the transaxle.
The exact location in the 98 cavalier is behind the engine toward the passenger side mounted onto the transmission with one nut and it has a plug with 2 wires on it. Can be easily accessed by jacking up the car and removing the passenger side front wheel.

I have a 1994 chevy astro awd that the transmission will not shift out of 1st the abs light is always on and my electronic speedometer always reads 0 mph what is wrong Ps hit a bump and all these things...


Hi, you will need to check out the speed sensor on the transmission. See if the sensor or it's wiring harness was damaged from hitting the bump. The sensor is mounted with a single bolt in the tail of the transmission and looks like the picture below. If everything looks OK from the outside, it may be that the sensor has failed. There is a sensor test procedure below, but please be very careful if you do this. A new sensor is about $35. Please let me know if you have any questions, and thanks for using FixYa.
