Where is the rev limiter on a 2005 Chrysler PT Cruiser?

The rev limiter on a 2005 Chrysler PT Cruiser isn't a physical component you can point to like a switch. It's a function within the Powertrain Control Module (PCM), also known as the Engine Control Unit (ECU). The PCM uses sensors to monitor engine speed and, when it reaches a predetermined RPM, it cuts or limits fuel delivery to prevent over-revving. There's no visual indicator on the dashboard; you'll only notice it when the engine abruptly stops accelerating near its maximum RPM.
