P0809 code definition

The P0809 Trouble Code indicates that there is a clutch position sensor circuit intermittent malfunction.

What the P0809 code means

When you have the P0809 code in your vehicle, it means that the powertrain control module has found a problem in the clutch position sensor circuit. Also called a clutch start switch, this needs to be in the closed position in order for the starter to work and engage. If it is not working properly, there is a chance that the vehicle will not start.

What causes the P0809 code?

The following are the common causes of the P0809 code:

What are the symptoms of the P0809 code?

In some cases, you might not have any symptoms even though this code is present. However, you may also find that the vehicle does not start. In some cases, the vehicle might start without the clutch depressed. Both of these issues can be very serious, and you do not want to wait too long to take the vehicle to a mechanic. There will likely be a Check Engine Light that turns on as well.

How does a mechanic diagnose the P0809 code?

The mechanic will start by using the OBD-II scanner to check the vehicle, as this can be a helpful tool when trying to determine the cause of the code. The mechanic will look for issues with the voltage and any other indicators of what is causing the code so they can find the best method of repair. The mechanic will also want to reset the code and then drive the vehicle, if it will start, to see if the code returns. This lets them know that the code wasn’t activated accidentally.

Common mistakes when diagnosing the P0809 code

Because this code can mean that the vehicle will not start, and the starter won’t engage, many mechanics mistakenly blame the starter. They might replace the starter and then realize that the problem is still there. The mechanic would then have to go over the vehicle again and try to find the actual cause of the problem.

How serious is the P0809 code?

Although some vehicles might not have any noticeable problems when this code first appears, it’s not a problem that you will want to drive around with. As soon as the Check Engine Light appears, it is important to take the vehicle to a mechanic who can service it and find the cause of the problem. As mentioned, in some cases, the vehicle might fail to start. This is naturally a huge issue. You do not want to come out of work or out of the store only to find that your vehicle no longer starts.

What repairs can fix the P0809 code?

The following are some of the repairs that the mechanic can make when trying to fix the P0809 code.

Additional comments for consideration regarding the P0809 code

Most of the time the powertrain control module is not at fault, and it will not need to be repaired or replaced. However, in vehicles that have more than 100,000 miles, the code, and other codes, could appear due to a problem with the PCM. It is never a good idea to assume that this is the problem though. Instead, make sure you bring your vehicle to a mechanic who has the skills and experience to take care of the problem.
