How to fix obd code 24 on 1985 chev el camino,vehicle speed sensor

There are several possible reasons why your cruise control may have stopped working. Here are some steps you can take to diagnose the issue:

1. Check the cruise control fuse: The first thing to check is the fuse that controls the cruise control system. Refer to your vehicle's owner manual to locate the fuse box and find the specific fuse for the cruise control. If the fuse is blown, replace it with a new one.
2. Check the brake light switch: The cruise control system is designed to disengage when you step on the brake pedal. If the brake light switch is faulty, the cruise control system may not work. You can test the switch by pressing the brake pedal and checking if the brake lights come on. If the brake lights don't come on, you may need to replace the brake light switch.
3. Check the speed sensor: The speed sensor is responsible for detecting the vehicle's speed and communicating it to the cruise control system. If the speed sensor is faulty or dirty, the cruise control system may not work. You can test the speed sensor with a multimeter or take your vehicle to a mechanic to have it tested.
4. Check the cruise control module: If all the above steps check out, the problem may be with the cruise control module itself. The module may be faulty and may need to be replaced. You can take your vehicle to a mechanic to have the module tested and replaced if necessary.

It's always recommended to consult with a certified mechanic or technician to diagnose and fix issues related to the cruise control system in your vehicle. They will have the expertise and necessary tools to troubleshoot the problem and provide the appropriate solution.

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

Note the diagram, at least check the fuse. Check trouble codes, related to cruise control. to check codes yourself, at least, you need an obd2 code reader that will read po codes as well as manufacturer specific codes. It is worth the investment, in my opinion. Make sure the brake lites work.

What engine speed sensor ? Location ? The vehicle speed sensor signal comes from the anti-lock brake control module , to the PCM -engine control module . Speed Information to the instrument cluster comes from the PCM on the CCD serial data bus , Suggest you google Chrysler CCD data bus . Are any warning lights lit on the instrument cluster ? ABS , Check engine etc... Sorry but I suggest you take your vehicle to a qualified repair shop that has the diagnostic tools to find the problem . http://www.cnblogs.com/shangdawei/p/3570499.html

In regions where smog checks are required to register your vehicle, YES. In regions where smog checks are not required, you should fix the CHECK ENGINE light anyway, as it is an important warning of engine issues.

According to http://repairpal.com/OBD-II-Code-P0500:

Vehicle Speed Sensor Malfunction
Symptoms

• Check Engine Light will illuminate
• Vehicle may not shift properly
• Speedometer may not operate correctly
• In some cases, there are no adverse conditions noticed by the driver
• In some cases, there may be performance problems and/or shifting problems.
• Other warning lights may come on such as the ABS light and Traction Control light.

Common Problems That Trigger the P0500 Code

• Defective Vehicle Speed Sensor
• Defective Speedometer
• Vehicle Speed Sensor wiring or connector
• Communication (CAN) bus problems
• Defective transmission or differential Vehicle Speed Sensor drive gear

Common Misdiagnoses

• Speedomter problem
• Internal Transmission problem
• ABS/Traction Control probelm
• Driveline problem

make sure 3rd brake light works, most likely you have a code in the EBCM (antilock brakes), some codes disable the cruise control, possible vehicle or output speed sensor or wheel speed sensor.

Try going to a local Checker, Autozone or O'Rielys for a code pull. Sounds like a " vehicle speed sensor" problem.

You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

Could be a problem with the wheel speed sensor or ABS sensor; first I suggest scanned the computer to know exactly what fault code is stored there. With this code number could send aditional details to fixed.
