Question

What should I look for on a 2004 Hyundai Santa Fe 3.5L with a P1193 code and no other codes? It will not idle

Answer 1

The diagnostic trouble code (DTC) P1193 on your 2004 Hyundai Santa Fe with a 3.5L engine indicates a problem with the Intake Air Temperature (IAT) Sensor Circuit High Input. This code is triggered when the Engine Control Module (ECM) detects an abnormally high voltage signal from the IAT sensor, suggesting that the intake air temperature reading is unusually low (since high voltage corresponds to low temperature in this sensor).

You probably need to replace the throttle body.
