B11D5 Possible Causes
- Faulty EVAP Temperature Sensor
- EVAP Temperature Sensor harness is open or shorted
- EVAP Temperature Sensor circuit poor electrical connection
- Faulty A/C Heater Module
First diagnose B11D5 code
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 terminals.
Cost of diagnosing the B11D5 code
Labor: 1.0The cost of diagnosing the B11D5 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
B11D5 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
B11D5 MeaningThe Evaporator Temperature Sensor is a variable resistor that changes in conjunction with temperature, or otherwise known as a thermistor. The Evaporator Temperature Sensor is located in the HVAC housing downstream of the A/C evaporator. The A/C Heater Module monitors the evaporator temperature by monitoring the voltage change of the Evaporator Temperature Sensor Signal circuit. If the monitored voltage drops below or rises above a predetermined voltage, a Diagnostic Trouble Code (DTC) will set.
