P0808 code definition

When the PCM in your vehicle records a P0808 trouble code, it means that there is a problem with the clutch position sensor circuit.

What the P0808 code means

When this code is recorded, it is because the clutch start switch has failed to close, and the starter can not engage. This is only an issue with manual transmissions. If it appears in a vehicle that has an automatic transmission, then there is probably a programming error within the PCM.

Keep in mind that the PCM will not always detect a problem on the first go-round. Sometimes, a code will be stored without the Check Engine Light coming on. In fact, it may take several cycles for the PCM to activate the Check Engine Light, and some vehicles may not activate the Check Engine Light at all in response to a P808 code.

What causes the P0808 code?

Most of the time, this code ends up being stored because the clutch position sensor is either defective or maladjusted. Other causes include open, shorted, or corroded wiring or connectors.

What are the symptoms of the P0808 code?

There may be no symptoms at all. Or you could experience:

How does a mechanic diagnose the P0808 code?

Your mechanic will first use a code reader and an ohmmeter to find out what is causing the P0808 code to appear. Then he or she will check the clutch position sensor. Other diagnoses will include”

Common mistakes when diagnosing the P808 code

The PCM I is hardly ever the problem, so replacing it before considering other causes for the P808 code is a mistake. Often, too, the starter or solenoid is blamed when the problem is actually with the clutch position sensor.

How serious is the P808 code?

Your Check Engine Light could come on, and a P808 code stored without you ever experiencing any problems. On the other hand, if your engine fails to start, then obviously you are not going to be going anywhere. This could be inconvenient. An engine that starts without you wanting or expecting it to, though, could be very dangerous. This is not something that you should neglect. For your own safety, and for the safety of other motorists and pedestrians, you should get this taken care of at your earliest convenience.

What repairs can fix the P808 code?

Often, it is a matter of replacing corroded or damaged wiring. Frequently, too, the clutch sensor needs to be replaced. In very rare instances, the PCM itself can be at fault, and may need to be replaced. Usually, though, the problem is with another component or series of components within the vehicle, since PCMs hardly ever fail.

Additional comments for consideration regarding the P808 code

Any wiring problem in your vehicle can be dangerous. If you suspect an issue, it’s best to see a mechanic as soon as possible.
