There are, however, several *related* sensors and switches that could impact power steering function, though they wouldn't be *directly* on the power steering system itself:
* Low fluid level switch (or sensor): While not strictly a "switch" in the on/off sense, a low fluid level sensor might illuminate a warning light on the dashboard. This doesn't directly affect power steering operation but alerts the driver to a critical condition that could lead to power steering failure.
* Sensors related to the engine's performance: The power steering pump is driven by the engine. Sensors monitoring engine speed, oil pressure, and other parameters could indirectly affect power steering function if the engine isn't running correctly.
It's crucial to note that if you're experiencing problems with your 2002 Ford Falcon's power steering, it's more likely due to issues with the:
* Power steering pump: This is the most common culprit.
* Power steering fluid: Low or contaminated fluid.
* Power steering hoses or lines: Leaks or blockages.
* Power steering rack and pinion: Internal wear.
If you're having power steering problems, taking your vehicle to a mechanic for diagnosis is recommended. Mentioning specific symptoms (e.g., groaning noise, difficulty steering, loss of assistance) will help them pinpoint the exact problem. Don't just assume a sensor is the issue without a proper inspection.
