Code B1947 Lincoln Description
The B1947 diagnostic trouble code for Lincoln vehicles indicates a Climate Control A/C Post Evaporator Sensor Circuit Short To Ground. This means that there is an electrical issue in the circuit that connects the A/C post evaporator sensor to the vehicle's climate control system. The post evaporator sensor is responsible for monitoring the temperature of the air after it has passed through the evaporator in the A/C system. When this sensor circuit is shorted to ground, it can cause inaccurate temperature readings, leading to improper climate control system operation.
Common Causes of B1947 Lincoln
- Damaged post evaporator sensor.
- Shorted wiring in the sensor circuit.
- Faulty climate control module.
- Corrosion or loose connections in the sensor circuit.
- Electrical issues in the climate control system.
Symptoms of B1947 Lincoln
- Inconsistent cooling or heating from the A/C system.
- Climate control system not responding to temperature adjustments.
- A/C system blowing hot air when set to cool or vice versa.
- Climate control system displaying error messages or warning lights on the dashboard.
How to Fix B1947 Lincoln
- Begin by diagnosing the specific cause of the short to ground in the sensor circuit using a diagnostic scanner.
- Inspect the post evaporator sensor for any visible damage and test its functionality.
- Check the wiring harness for any signs of damage, corrosion, or loose connections.
- Test the climate control module to ensure it is functioning correctly.
- Repair or replace any damaged components, such as the sensor, wiring harness, or climate control module, as needed.
