Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




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.

Possible source
- Signal cable interference.
- Defective throttle position (TP) sensor.
- Intermittent open-circuit in the signal cable.
- Intermittent short-circuit to supply voltage or ground in the signal cable.

Fault symptom[s]
- The DSA warning lamp lights.
- The anti-spin function is not operative while the DSA function is disengaged.
