The P1500 code is fairly simple to decode: it’s an issue that has to do with your vehicle’s speed sensor, which is the sensor it uses to indicate how fast the car is moving. The vehicle will constantly check your speed sensor in accordance with other onboard sensors, ensuring that all of them are functioning as expected. If the speed sensor seems like it’s not working appropriately, given the readings from the other onboard sensors, then your vehicle may send this code.
More About the P1500 Code
The P1500 code may mean a variety of things depending on your vehicle’s make and model. This code often indicates an issue with the vehicle speed sensor for Ford, Hyundai, Kia, Lincoln, Mazda, and Mercury vehicles. Outside of this, you might see these codes:
- Starter Signal Circuit – Buick, Cadillac, Chevrolet, GMC, Lexus, Suzuki, Toyota
- Alternator Terminal Circuit Conditions – Chrysler, Dodge, Jeep, Mitsubishi
- Idle Speed Control Valve Stuck Open – BMW, MINI
There are also plenty of other manufacturer-specific code descriptions. Make sure you’re looking at the description for the code, not just the code itself, so you can get to the point of the problem as quickly as you can.

What Are the Symptoms of a P1500 Code?
One of the more prominent symptoms of the P1500 code is that the speedometer may not be functioning properly. This is most noticeable if the speedometer is especially broken, such as reading 30 MPH when you’re on the highway. Other problems can also include the engine running rough at certain speeds, especially higher speeds, which may happen due to the transmission shifting abnormally or the power cutting out, especially when downshifting. In some cases, your vehicle may enter Limp Mode. The check engine light should also come on to alert you to a problem.
What Are Some Causes of a P1500 Code?
The problem with this code generally happens because of a problem with the vehicle speed sensor itself. These may have to do with the vehicle speed sensor wiring or with the vehicle speed sensor itself, whether because the sensor is in bad condition or because the sensor has failed in some way. While these are the most common causes, the P1500 code may also trigger due to other issues with the vehicle speed sensor process, including low battery or issues with other onboard sensors.
How Serious Is the P1500 Code?
The main reason that the P1500 code can be extremely serious is that you need to know how fast you’re going in order to stay safe on the road. While you may be able to match the speed of other people on the road when you’re in a well-populated area, that failsafe becomes much more difficult if you’re on a stretch of road without many other vehicles. Additionally, if you are having issues with your vehicle’s effective running, including Limp Mode or power outages, this can cause its own array of serious concerns, all of which indicate that you need to fix the problem as soon as possible.
Can I Still Drive with a P1500 Code?
While you may physically be able to drive with a P1500 code active, it’s likely to be difficult and result in motor irregularities and concerns with driving overall. Experts do not recommend that you drive with this code active; if you notice that your speedometer is showing issues, including measuring a very low MPH or not working at all, you should stop driving your vehicle immediately and start looking for ways to fix the problem.
How Easy Is It to Diagnose a P1500 Code?
The diagnostic process for the P1500 code can be a bit difficult; while it’s very likely that the problem is with the vehicle speed sensor, there are many areas where the problem might lie. This can include the vehicle speed sensor’s wiring, the electrical connections actually within the sensor itself, or the connections within other areas of the vehicle. If you’re not confident in understanding wiring and electricity within your vehicle, then you might want to leave this one up to an expert.
How Difficult Is It to Inspect a P1500 Code?
The inspection process for the P1500 code can be difficult because the vehicle speed sensor is not a common one for people who do a lot of DIY or hobbyist work on the engine. There are many other elements of the engine that you might be used to managing, but this generally isn’t one of them. If you’re not confident in handling this aspect of an engine, then this probably isn’t the time to learn, and it’s better to talk to an expert.
