Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P1193 Dodge code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
The Inlet Air Temperature (IAT) Sensor is a 2-wire thermistor, as intake air temperature increases, thermistor resistance, and signal voltage decrease. Cold Engine, voltage is sent through a high resistance circuit in Powertrain Control Module (PCM). Warm Engine, voltage is sent through a low resistance circuit in PCM. PCM dual circuit improves IAT accuracy overall temp ranges. PCM monitors IAT voltage to help determine air density, due to temperature, for fuel calculations. The circuit is monitored when the engine is running. Diagnostic Trouble Code (DTC) will set when Inlet Air Temperature (IAT) sensor voltage is more than 4.9 volts.
