Causes

Open or shorted sensor element
Damaged wiring or chafed insulation in the sensor harness
Corroded or loose connector terminals
Poor ground or intermittent connector contact
Faulty HVAC (climate control) module or input circuit
Sensor contaminated, obstructed or incorrectly positioned in the duct

Symptoms

Incorrect cabin face-vent temperature (too hot or too cold compared to setting)
Slow or poor air temperature control from face vents
Climate control displays inconsistent or implausible temperature readings
DTC/B13E2 stored and may illuminate HVAC warning/message
Automatic climate functions (dual-zone balancing, auto mode) behaving erratically

What to check

Connect a diagnostic scan tool, read freeze frame and live data for the face air duct temp sensor
Clear the code and operate HVAC to see if code returns
Visually inspect sensor and harness for damage, water ingress or obstruction in the duct
Check connector terminals for corrosion, bent pins or poor mating
Back-probe connector and measure reference voltage and signal while changing temperature at the sensor
Measure sensor resistance at ambient and while warming/cooling (ice/warm air) to confirm NTC behavior

Signal parameters

Sensor type: typically an NTC thermistor (resistance decreases as temperature rises)
Nominal behavior: resistance vs temperature should change smoothly when warmed/cooled
Typical module interface: module supplies reference (often 5V) and measures voltage across sensor—expected signal typically between ~0.2–4.8 V depending on temperature (manufacturer specifics vary)
Example reference point (example only): ~10 kΩ at 25 °C for many HVAC NTC sensors (verify with vehicle-specific data)
Fault indications: open circuit (very high resistance/OL), short to ground (very low resistance), or a fixed/stuck voltage indicate sensor or wiring fault

Diagnostic algorithm

Use a scan tool to confirm B13E2 is current or historic, note freeze-frame data and monitor face air duct temp live value.
Clear the code and reproduce conditions to see if code returns and observe live sensor data behavior.
Locate the front-left face air duct temperature sensor (consult vehicle-specific guide) and visually inspect for contamination, dislodgement or damage.
With ignition ON, back-probe the sensor connector: verify reference voltage from HVAC module and the sensor signal voltage while monitoring live data.
Remove the sensor and measure its resistance at ambient; then warm and cool sensor (warm breath or warm water / ice) and confirm resistance changes smoothly (NTC behavior).
If resistance does not change or is out of expected range, replace the sensor. If resistance is OK but signal voltage is erratic, inspect/repair harness and connector or test continuity to the HVAC module.
Perform wiggle tests on harness while watching live data; repair any intermittent wiring or connector faults found.
If wiring and sensor check OK, test or replace the HVAC control module input circuit only after verifying software calibration and after consulting manufacturer technical service bulletins.
After repairs, clear codes, verify proper operation in all climate modes and confirm no recurrence of the fault.

Likely causes

Connector corrosion or loose pin at the sensor
Broken/chafed wiring between sensor and HVAC module
Failed NTC-type temperature sensor element
Intermittent contact due to vibration/wire routing

Fault status

⚠️ Status

Front left face air duct temperature sensor circuit fault — implausible/open/short or out-of-range signal detected.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-1.5 hours
