The throttle position (TP) sensor signal from the engine control module (ECM) is a pulsed signal (between approximately 0 V and battery voltage) with a fixed frequency (approximately 50 Hz). The pulse ratio (% duty) changes as the throttle opens. Diagnostic trouble code (DTC) DSA-232 is stored if the DSA control module registers that the frequency deviates or that the pulse ratio is based on implausible maximum or minimum values.

Substitute Value 

The DSA function is disengaged.
