True or False: Two- and three-wire configurations are more common than four-wire sensors in today's engine-control systems.

The assertion that two- and three-wire configurations are more common than four-wire sensors in today's engine-control systems is indeed accurate.

Two-wire sensors generally use the power supply line for both the power and the signal, reducing wiring complexity and installation costs. Similarly, three-wire sensors typically separate the power and ground leads from the signal wire, which can provide improved performance with minimal additional complexity. These configurations are widely utilized due to their efficiency and ease of integration into various engine control systems, particularly in applications where space and weight are constrained.

In contrast, four-wire sensors, though they have their own advantages like improved accuracy by compensating for voltage drop across the wires, tend to be less prevalent in standard engine-control systems where simplicity and cost-effectiveness are prioritized. This trend can vary with specific systems or applications, but in general engineering practice, two- and three-wire configurations are favored for their balance of performance and ease of use.

Thus, the answer confirming the higher prevalence of two- and three-wire configurations is well-supported by the current trends in engineering design and application.
