P0500
Fix within a few daysYour vehicle's computer isn't getting a proper signal from the Vehicle Speed Sensor (VSS). This sensor tells the car how fast it's moving.
Code P0500 means your vehicle's speed sensor has a malfunction. Common causes: faulty speed sensor (70%), wiring issues (20%). Drivability: Yes, but fix within a few days. Repair cost: $20-$100 DIY, $70-$300 professional.
Can I Drive With P0500?
Yes, for short trips only
Essential trips under 10 miles, avoid highways and situations requiring precise speed control. Be aware of your speed using a GPS app.
Stop driving immediately if: Flashing CEL, significant power loss, or severe transmission issues like being stuck in gear.

Common Causes of P0500
Parts most likely causing this code, ranked by probability
The VSS itself has failed internally and is no longer sending an accurate speed signal to the vehicle's computer.
70% of P0500 cases are fixed by replacing this part
Damaged, corroded, or loose wiring and connectors prevent the VSS signal from reaching the computer correctly.
20% of P0500 cases are fixed by repairing wiring or connectors
If the VSS signal is routed through the ABS module, a fault in the module can prevent the speed signal from being properly transmitted.
8% of P0500 cases are fixed by replacing or repairing the ABS module
A rare internal fault in the main engine computer can cause it to misinterpret or fail to receive the VSS signal.
2% of P0500 cases are fixed by replacing the PCM/ECM
Check These First (Before Buying Parts)
- 1. Visually inspect the Vehicle Speed Sensor (VSS) wiring and connector for any obvious damage, fraying, or corrosion.
- 2. Ensure the connector is securely plugged into the VSS.
How to Diagnose P0500
- 11. Connect an OBD-II scanner to confirm P0500 and check for other related codes.
- 22. Visually inspect the Vehicle Speed Sensor (VSS) and its wiring harness for any obvious damage, corrosion, or loose connections.
- 33. Use a multimeter to check for proper voltage supply to the VSS and signal output while rotating the wheel (if accessible) or driving slowly.
- 44. Use a scan tool with live data to monitor the VSS reading while driving; compare it to GPS speed if possible.
- 55. If the VSS signal is erratic or absent, disconnect the VSS and test the sensor directly if possible, or replace it.
- 66. If the VSS tests good, inspect the wiring continuity from the VSS connector back to the PCM/ABS module.
P0500 on Popular Vehicles
Toyota Camry
2002-2024P0500 on a Camry often points to the transmission output speed sensor. This sensor is crucial for speedometer function and transmission shifting. It's typically accessible on the transmission case.
75% fixed by replacing the VSS
Honda Accord
2003-2024Honda Accords frequently experience P0500 due to a failing VSS, often located on the transmission. Wiring issues are also common, especially near the sensor connector due to heat and vibration.
70% fixed by replacing the VSS
Ford F-150
2004-2024On Ford F-150s, the VSS location can vary. Older models might have it on the rear differential, while newer ones integrate it into the transmission or ABS wheel speed sensors. Always confirm the specific sensor location for your year and drivetrain.

Frequently Asked Questions
What does P0500 mean?
P0500 indicates that your vehicle's computer is not receiving a correct signal from the Vehicle Speed Sensor (VSS), which measures how fast your car is moving.
Can I drive with P0500?
Yes, you can drive with P0500, but you should fix it within a few days. Your speedometer might not work, cruise control will be disabled, and your transmission shifting could be erratic. This can be unsafe and uncomfortable.
Will P0500 clear itself?
No, P0500 will not clear itself. The underlying issue, usually a faulty sensor or wiring, needs to be repaired. Once the repair is made, you will need to clear the code with an OBD-II scanner.
How do I fix P0500 myself?
Start by visually inspecting the Vehicle Speed Sensor (VSS) and its wiring for damage. If the wiring looks good, replace the VSS. It's often a simple bolt-on component on the transmission or rear differential.
How much does it cost to fix P0500?
A DIY fix for P0500, typically replacing the VSS, costs $20-$100 for the part. Professional repair at a shop will cost $70-$300, including parts and labor.
P0500 keeps coming back - why?
If P0500 keeps returning, the initial diagnosis was likely incomplete. The problem might be in the wiring harness leading to the VSS, a faulty ABS module, or, in rare cases, an issue with the Powertrain Control Module (PCM) itself.
Will P0500 fail emissions/smog test?
Yes, P0500 will cause your vehicle to fail an emissions or smog test. A Check Engine Light (CEL) for any reason will prevent your vehicle from passing, and the VSS is a critical input for the emissions system.
What's the difference between P0500 and P0501?
P0500 indicates a general malfunction or no signal from the Vehicle Speed Sensor. P0501 specifically points to a 'Range/Performance' issue, meaning the sensor is sending a signal, but it's inconsistent or outside expected parameters for the vehicle's actual speed.
P0500 on Toyota Camry?
On many Toyota Camry models, P0500 is commonly caused by a faulty transmission output speed sensor, which acts as the VSS. It's usually located on the transmission housing and is a straightforward replacement.
Questions to Ask Your Mechanic
Did you check the live data from the Vehicle Speed Sensor (VSS) while driving?
Good answer: Yes, I monitored the VSS signal on the scanner and it was erratic/zero/inconsistent with the actual speed. This confirms the sensor or its circuit is faulty.
Have you inspected the wiring harness and connector to the VSS for corrosion or damage?
Good answer: Yes, I performed a visual inspection and also checked for continuity and proper voltage at the VSS connector. The wiring is solid, which points to the sensor itself.

Beginner-friendly - most VSS replacements require basic hand tools and are easily accessible on the transmission or differential.
Cost of Waiting
Ignoring P0500 can lead to unsafe driving conditions due to an inoperative speedometer and erratic transmission shifting. Continued driving with incorrect speed signals can also cause premature wear on transmission components. A $50 sensor replacement now prevents potential transmission damage costing $1,500-$4,000 later.
While You're In There...
Applying dielectric grease to electrical connectors prevents corrosion and ensures a solid electrical connection, which is crucial for sensor signals.
If you find any damaged or corroded wiring near the VSS, a simple wire repair kit allows you to fix it on the spot and prevent future issues.
Tools You'll Need
- OBD-II scanner
- Basic socket/wrench set
- Flathead screwdriver (for connectors)
- Multimeter (optional, for advanced diagnostics)
P0500 is a common sensor code. The repair is usually straightforward and inexpensive, and your vehicle's speedometer and transmission will function correctly again.

Your Next Steps
Step 1: Visually inspect the Vehicle Speed Sensor (VSS) and its wiring harness for any obvious damage, corrosion, or loose connections. Ensure the connector is fully seated.
Step 2: If the visual inspection doesn't reveal the issue, replace the Vehicle Speed Sensor (VSS). This is the most common fix for P0500.
Step 3: After replacing the VSS, clear the code with an OBD-II scanner and test drive the vehicle to confirm the repair. If the code returns, further electrical diagnosis of the wiring or ABS module is needed.
