Diagram Ref No 3

The park / neutral position switch is an essential safety component fitted to Porsche models with automatic transmissions. Over time, internal electrical contacts can wear, contamination can affect operation, or the switch can become damaged or misaligned, leading to intermittent starting issues or incorrect gear position recognition. This OE Match replacement restores dependable operation and factory-style functionality, making it ideal for routine maintenance, repairs, and Porsche restoration projects.  

What This Product Does:
  • Detects when the transmission is in Park or Neutral.
  • Allows the engine to start only in the correct selector positions.
  • Prevents accidental engine starting while a drive gear is engaged.
  • Sends accurate gear position signals to the vehicle's electrical systems.
  • Supports safe and reliable automatic transmission operation.
  • Replaces worn or faulty original switches.
  • Provides an OE-style fit and dependable performance.

Symptoms Of Wear Or Failure:
  • Engine will not start in Park or Neutral.
  • Intermittent starting problems.
  • Vehicle starts while in gear.
  • Incorrect gear position indication.
  • Transmission warning lights or fault codes.
  • Inconsistent operation of the gear selector.
  • Worn, damaged, or contaminated switch contacts.
  • Age-related deterioration of the original component.

Why Replacement Matters:

  • The park / neutral position switch is a critical safety component that ensures the engine can only be started when the automatic transmission is in Park or Neutral. A worn or faulty switch can lead to intermittent no-start conditions, inaccurate gear position signals, or, in severe cases, allow the engine to start while a drive gear is selected, creating a potential safety risk.
  • Replacing a defective park / neutral position switch restores reliable starting, accurate transmission position detection, and the safe operation of your Porsche's automatic transmission system. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match component provides the correct fit, dependable performance, and long-lasting durability, making it an excellent choice for maintenance, repairs, and restoration projects.
