P0500 Infiniti Code - Vehicle Speed Sensor
Quick Answer
The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. Common causes include Faulty Vehicle Speed Sensor, Faulty Wheel Speed Sensor, Vehicle speed sensor harness or connectors is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0500 Infiniti Description
Most Infiniti Models 2006-2011:
When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current signals (rectangular wave) and transmits them to the Anti-lock Brake System (ABS) Actuator and Electric Unit (Control Unit). The vehicle speed signal is sent to the combination meter from the ABS Actuator and Electric Unit (Control Unit) by Controlled Area Network (CAN) communication line. The combination meter then sends a signal to the Engine Control Module (ECM) by CAN communication line.
Most Infiniti Models 2012 + :
The Engine Control Module (ECM) receives vehicle speed signals from two different paths via CAN communication line: One is from the Anti-lock Brake System (ABS) Actuator and Electric Unit (Control Unit) via the combination unit and the other is from Transmission Control Module (TCM).
What are the Possible Causes of the DTC P0500 Infiniti?
- Faulty Vehicle Speed Sensor
- Faulty Wheel Speed Sensor
- Vehicle speed sensor harness or connectors is open or shorted
- Vehicle speed sensor circuit poor electrical connection
- Wheel speed sensor harness or connectors is open or shorted
- Wheel speed sensor circuit poor electrical connection
- Faulty Anti-lock Brake System (ABS) Control Unit
- Faulty Engine Control Module (ECM)

can you please post a digital picture of the sensor and where it located in the car exactly
-
What model and year is your Infiniti? each model have a different sensor location
-
Unfortunately We don't have a picture, but you can find and image of the location here: https://www.autocodes.com/p07...

It's not part of the ABS system. There is a separate sensor to measure the vehicle speed:

I have a 1997 infinity i30 with the code po500 I have changed the speed sensor already n the speedometer is working fine but the code this comes up. What else could the problem be???

The speedometer receives the signal from the speed sensor and then transform the signal and sends the signal to the Engine Control Module (ECM). The speedometer is showing the correct speed, but it's probably not sending the signal to the ECM or it's sending the wrong signal. Start by checking the screws that connects the speedometer to the circuit board.

I have a 2008 infiniti G35 and it's showing me P0500 Sensor A i can't seem to find sensor A and what's really the problem the car has the abs light on, brake, traction control the slip , i think the key light also witch it's weird do i need to change the trans axle sensor or the front one's i have a back up camera and it has the guide lines that tell you where you are backing up into but mine are to an angle they are suppose to move when the steering wheel is being moved.

I have Qx70 2014 with P0500 code sensor A ,need help to find the location, someone know ?

Hello I have an M45 2007 with p0500 would that be the the trans speed sensor it comes up twice and my speedometer doesn't work along with a p0460 code but I'm not sure what's triggering what
-
The Speed Signal it's actually a calculation signal. All four ABS Sensors (One on each wheel) sends the signal to the ABS Control Unit and then sends the signal to the "Unified Meter" (Meter Gauges Assembly) to control the speedometer. Unfortunately, the P0500 code does not specified if the problem is one of the ABS Sensors, the ABS Control Unit or the Unified Meter, more tests need to be done to find the exact problem. The most common problem is the Unified Meter, but I recommend taking your vehicle to a shop to diagnose the problem.
The P0460 code is for the Fuel Level Sensor, which is also related to the Unified Meter.

Thanks for the question. On your 2017 Infiniti QX70, with P0500 (Vehicle Speed Sensor) and P0720 (Output Speed Sensor), both codes are related to how the transmission and ECM read vehicle speed.
Here’s the breakdown:
- The P0720 usually points to the output speed sensor on the transmission — this sensor measures how fast the transmission output shaft is spinning and is critical for shift timing and speed calculations.
- The P0500 can be triggered if the ECM doesn’t get a proper speed signal, often because of a bad output speed sensor, bad wiring, or even a bad ABS sensor in some cases.
Location:
The output speed sensor is mounted directly on the transmission, usually on the rear section (tail housing) near where the driveshaft connects. You’ll typically find it screwed into the side of the transmission with a small two-wire connector attached.What I would recommend:
- Inspect the sensor and the wiring harness for damage, corrosion, or loose connections first.
- If wiring looks clean, the sensor itself is likely bad and will need to be replaced.
- Make sure the replacement is a good quality sensor — sometimes cheaper aftermarket ones cause issues again.

On the 2015 Infiniti Q50, there isn’t a traditional output speed sensor like on older transmissions. Instead, the transmission uses internal speed sensors that are built into the transmission control module (TCM) and valve body.
The output speed is typically calculated using data from these internal sensors and the wheel speed sensors—especially the rear wheel speed sensors. If you're dealing with a P0500 code or related issue, it's worth checking the rear ABS wheel speed sensors and their wiring first.
If you're chasing a transmission-related speed sensor problem, that usually requires dropping the transmission pan and inspecting the internal harness and sensors. Let me know what symptoms you're having and I can help narrow it down.
