2004 Hyundai Santa Fe P1193 Fault: Throttle Actuator Control System Limp Home at Low RPM
I own a 2004 Hyundai Santa Fe with a 3.5L engine that is currently displaying Diagnostic Trouble Code (DTC) P1193, indicating a 'Throttle Actuator Control System' fault resulting in limp-home mode at low engine RPM. What are the recommended steps to diagnose and fix this issue?
According to repair manuals such as Alldata.com or equivalent, thorough diagnostic testing is required to identify the root cause of P1193 in a Hyundai Santa Fe. Possible causes include: a faulty Electronic Throttle System (ETS) motor, defective ETS control module, an open or shorted ETS harness, or poor electrical connections within the ETS circuit.
