In-Vehicle Temperature Sensor Circuit
The HVAC control module has detected an implausible signal from the in-vehicle temperature sensor — typically an aspirated sensor in the dashboard. Automatic climate control regulates cabin temperature using this signal.
Affected components
- In vehicle temperature sensor
- Hvac control module
Common causes
- High likelihood: In-vehicle temperature sensor failed
- Medium likelihood: Aspirator fan or duct blocked
Possible symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
