P0500 Code - What’s Causing My Speedometer Issues?

Technical Discussions
1

I’m having some trouble with my car’s speedometer recently. Every time I check the dashboard, it seems to be getting stuck, and the check engine light has come on with a P0500 diagnostic trouble code. Has anyone else dealt with this?

What I’ve Noticed:

  • The speedometer occasionally drops to zero, even when I’m driving.
  • It feels like the transmission isn’t shifting properly at times.
  • No apparent issues with the tire size or any recent changes to the vehicle.

Troubleshooting I’ve Done:

  • Checked the wiring around the vehicle speed sensor but didn’t find anything obvious.
  • Cleaned the sensor connection points, hoping it might be a corrosion issue.

What should I check next? Some friends suggested it might be something more severe, like issues in the transmission or even the ECU. Is it worth trying to replace the speed sensor first before going deeper?

Any advice or solutions that could help me out would be appreciated! Thanks in advance!

A common symptom of a malfunctioning vehicle speed sensor is erratic speedometer readings. You might notice that the needle jumps around or doesn’t reflect your actual speed at all.

Exactly! I’ve also experienced issues with my cruise control, which seems to lose connection when the speed sensor acts up.

In addition to speedometer issues, have you guys noticed any abnormal gear shifting? My car seems to hunt gears all the time when the sensor is off.

Totally! Gear shifting can become erratic too. My transmission started behaving weirdly before throwing the P0500 code, which has freaked me out a bit.

That’s a great point! It’s frustrating when you can feel the car struggling to shift properly.

I also want to point out that the speedometer can sometimes just freeze. Has anyone else experienced that?

Yes! My speedometer just stopped working completely once before it was replaced, really unnerving!

So, what do you all suggest for a fix? Is it a DIY project, or should I go straight to a mechanic?

I think it depends on your skill level. Some speed sensors are easy to access and change out yourself if you’re handy. But don’t hesitate to consult a mechanic if you’re unsure!

11

Great point! Just make sure you have the right replacement part. Some sensors can be pricey!

12

If it helps, I once tried to replace mine and ended up with more problems! So definitely know your limits…

Haha, that’s classic! Sometimes keeping it simple and going to a professional can save you from that headache.

Ultimately, it’s essential to address these symptoms sooner rather than later. Otherwise, you might find yourself in a tricky situation! Stay safe on the roads.

I’m dealing with a P0500 code as well! I’ve heard that it may involve either the vehicle speed sensor (VSS) or the wiring that connects to it. Has anyone tried using a multimeter to check the sensor’s resistance?

16

Absolutely! I recently had a similar issue. Double-checking the connectors helped me resolve it quickly. It was just some corrosion!

17

Don’t forget to inspect the tone ring! Sometimes a cracked or dirty tone ring can also throw a P0500 code. It’s worth a look!

Good point! I didn’t realize how crucial that was until I faced a similar problem. It’s often overlooked!

Exactly! A good scan tool can save you so much hassle. But don’t forget to verify the sensor’s integrity too!

Have you all checked the vehicle’s speed sensor signal? You can usually do this with a scan tool. It’s a straightforward test that can lead you in the right direction.
