The clutch pedal switch on a Porsche 986 Boxster (1997–2004) is a small but critical component. It signals the engine control unit (ECU) that the clutch pedal is fully depressed, allowing the starter motor to engage and enabling cruise control. When this switch fails, you may experience a no-start condition, intermittent cruise control, or a check engine light. This guide covers symptoms, diagnosis, replacement options, and where to buy a quality part—including from Pelican Parts.

Symptoms of a Faulty Clutch Pedal Switch
A failing clutch pedal switch typically causes one or more of these issues:
- Engine won’t crank: The starter motor does not engage when the ignition key is turned.
- Cruise control inoperative: The system may not activate or drops out unexpectedly.
- Check engine light: The ECU detects a signal fault and stores a diagnostic trouble code (e.g., P0704 or P0833).
- Intermittent starting: The car starts fine sometimes but not others.
- Electrical anomalies: In rare cases, the switch failure can affect other systems tied to the clutch pedal.
Diagnosing the Problem
Before replacing the switch, confirm it is the culprit. Here’s how.
Visual Inspection
Locate the clutch pedal switch behind the pedal assembly. It is a plastic plunger-type switch that contacts the pedal arm when the pedal is pressed. Check for:
- Broken or missing plunger.
- Loose connector or corroded terminals.
- Visible cracks or damage to the switch body.
Testing with a Multimeter
If the switch appears intact, test its continuity:
- Disconnect the electrical connector.
- Set your multimeter to resistance (ohms).
- With the pedal at rest (up), the switch should be open (infinite resistance).
- Press the pedal fully – the switch should close (near zero resistance). If readings differ, the switch is defective.
Choosing a Replacement Switch: OEM vs Aftermarket
You have two main options: OEM Porsche or aftermarket parts like those sold by Pelican Parts.
OEM Porsche: The genuine part (996-613-111-00) offers guaranteed fit and longevity. It costs around $60–$80 from a dealer. For many owners, the higher price is worth the peace of mind.
Aftermarket (e.g., Febi, URO): Pelican Parts stocks several quality aftermarket switches priced between $20 and $40. These are often made in the same factories as OEM parts, but materials and durability can vary. Some users report premature failure with budget switches, while others have had good luck with brands like Febi. For a part that is easy to replace, an aftermarket option can be a cost-effective choice.
Recommendation: If you plan on keeping the car long-term, consider OEM. For a quick fix or if you are on a budget, a reputable aftermarket switch from Pelican Parts is fine.
Step-by-Step Replacement Procedure
Replacing the clutch pedal switch on a 986 is a straightforward DIY job that takes about 30 minutes.
Tools and Parts Needed
- New clutch pedal switch (OEM or aftermarket)
- Flathead screwdriver or trim tool
- Flashlight
- Possibly a T20 Torx bit (for some pedal cover screws)
Removing the Old Switch
- Disconnect the battery negative terminal (optional but recommended for safety).
- Remove the lower dash panel under the steering column. It is held by a few screws or clips.
- Locate the clutch pedal switch – it is clipped into a bracket above the pedal arm.
- Unplug the electrical connector by pressing the locking tab and pulling gently.
- Twist the switch 90 degrees counterclockwise (or press the release tab depending on design) and pull it out.
Installing the New Switch
- Align the new switch with the mounting hole.
- Insert and twist clockwise until it clicks into place.
- Plug in the electrical connector – it should snap firmly.
- Reinstall the lower dash panel and reconnect the battery.
Testing the Repair
- Press the clutch pedal fully and try to start the engine. It should crank normally.
- If your car has cruise control, test it on a safe road.
- Use an OBD-II scanner to clear any stored codes and ensure the check engine light stays off.
