Check Engine Light

P0805 code definition

When the PCM (powertrain control module) detects a problem with the clutch position sensor (also referred to as the clutch start switch) in a manual transmission vehicle, the P0805 code is stored and the Check Engine light is illuminated.

What the P0805 code means

When this code is stored, it indicates that there is a problem with the clutch position sensor, which can have a number of negative effects on the drivability of the vehicle.

What causes the P0805 code?

In most cases, a P0805 code is stored because the clutch position sensor has been improperly adjusted or has come out of adjustment. This code may also occur as a result of a problem in the wiring and/or connectors for the clutch position sensor, as well.

What are the symptoms of the P0805 code?

While the Check Engine light will always be illuminated when a P0805 code is stored, the driver may not notice any other problems or symptoms affecting the vehicle’s performance or drivability. Some symptoms that may occur include:

  • Higher or lower than normal engine speeds when the clutch is depressed.
  • Ability to start the vehicle without depressing the clutch.

How does a mechanic diagnose the P0805 code?

After detecting the code with an OBD-II scanner, the mechanic will then perform a visual inspection of the clutch position sensor circuit and all related components. They will also use an ohmmeter to test the circuit to find out if there are any shorts or if there is any other damage to the circuits wiring or connectors.

After performing each test and taking each diagnostic step, the mechanic will use a scanner to clear the code(s) in the PCM and then take the vehicle for a test drive to see if the P0805 code is stored again. Then they will move on to the next step.

Common mistakes when diagnosing the P0805 code

The most common mistake when diagnosing a P0805 code is to assume that the problem is with the starter or solenoid when the actual cause of the issue lies with the clutch position sensor and/or its circuit.

How serious is the P0805 code?

Though the symptoms associated with a P0805 code are generally rather benign, this code can actually be quite dangerous for vehicle with remote start features. Because the vehicle may start without the clutch depressed, this could result in a situation in which the vehicle can start to move before the driver has a chance to get inside and control it.

What repairs can fix the P0805 code?

In most instances, re-adjusting or replacing the clutch position sensor will solve the problem and allow the code to clear without returning. In some cases, the wiring or connectors for the clutch position sensor’s circuit will need to be replaced, and/or the clutch position sensor may be faulty and may need to be replaced.

Additional comments for consideration regarding the P0805 code

Even if you do not notice any other symptoms and you do not have a remote start feature on your vehicle, it is important to have this issue addressed as soon as possible. Simply having the Check Engine light illuminated is enough to prevent your vehicle from passing an OBD-II emissions test, which – in most states – will prevent you from renewing your vehicle’s registration and legally driving it.

Extremely knowledgeable and nice. Informed in depth of everything that was going on with the car because when I took it to a car shop they wanted me to pay $3000 for a transmission but Kevin explained that that was far from the case. Kevin saved me alot of money. I would highly recommend him.
