DTC P0734 Lincoln

Description

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. If the engine control module (ECM) registers a fault in the signal from the throttle position (TP) sensor, the engine control module (ECM) transmits a special throttle position (TP) sensor signal to the DSA control module. This informs the DSA control module that the throttle position (TP) sensor signal to the engine control module (ECM) is faulty. Diagnostic trouble code (DTC) DSA-233 is stored when the DSA control module has received this signal. Note!The diagnostic trouble code (DTC) is only stored as long as the ignition is on the engine is running and the fault is permanent. If the fault in the engine management system disappears (the fault becomes intermittent) the diagnostic trouble code (DTC) in the DSA control module will no longer be stored.
