Enabling Conditions And Possible Causes - Ambient Air Temp Sensor

2023 Dodge and Ram Durango R/T Plus, AWDSECTION Enabling Conditions And Possible Causes - Ambient Air Temp Sensor
WARNING: This page is about a different variant/trim than selected.
MONITORING CONDITIONS
Circuit Low/High Faults  - With the ignition on, battery voltage above a calibrated threshold.
Performance Fault  - With the ignition on after an eight hour cold soak on the previous engine off cycle. Ambient Air, Intake Air, and Engine Coolant Temperature values are above -64°C (-83°F).
FAULT SETTING CRITERIA
Circuit Low Fault  - The sensor signal voltage is below a calibrated threshold. The threshold is typically in the 0.1 volt range.
Circuit High Fault  - The sensor signal voltage is above a calibrated threshold. The threshold is typically in the 4.9 volt range.
Performance Fault  - The sensor signal voltage is irrational - typically not within 10°C - 15°C (18°F - 27°F) of the other engine temp sensors.
POSSIBLE CAUSES
TEMP SENSOR HARNESS CONNECTOR DAMAGED OR NOT CONNECTED COMPLETELY (CIRCUIT HIGH/PERFORMANCE FAULT)
TEMP SENSOR SIGNAL CIRCUIT SHORTED TO GROUND (CIRCUIT LOW FAULT)
TEMP SENSOR SIGNAL CIRCUIT SHORTED TO THE SENSOR GROUND CIRCUIT (CIRCUIT LOW FAULT)
TEMP SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE (CIRCUIT HIGH FAULT)
TEMP SENSOR SIGNAL CIRCUIT OPEN/HIGH RESISTANCE (CIRCUIT HIGH/PERFORMANCE FAULT)
TEMP SENSOR RETURN CIRCUIT OPEN/HIGH RESISTANCE (CIRCUIT HIGH/PERFORMANCE FAULT)
FAULTY TEMP SENSOR (OPEN, SHORTED OR DRIFTED OUT OF RANGE)
FAULTY ELECTRONIC CONTROL UNIT (ECU)
RENDER: 1.0x

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
