Code B1310 Chevrolet Description

The Instrument Panel Module (IPM) monitors the temperature sensors to maintain the comfort level inside of the vehicle. The temperature sensors are a 2 wire negative temperature co-efficient thermistor. The IPM applies 5 volts to internal input resistors that are connected to the signal circuits of the air temperature sensors. The IPM provides the ground to the air temperature sensors through the low reference circuit. The IPM monitors the voltage drop across the air temperature sensors and uses the inputs for automatic control calculations. When the air temperatures are cold, the resistance of the sensors are high and the voltage signals are high. When the air temperatures are hot, the resistance of the sensors are low and the voltage signals are low. The IPM converts the voltage values to count values where one volt is approximately equal to 51 counts.

Frequently Asked Questions about B1310 Chevrolet Code

1. What does OBDII code B1310 mean on a Chevrolet?

Code B1310 refers to an issue with the Ambient Air Temperature Sensor, indicating a problem with the sensor's circuit or its ability to provide accurate temperature readings.

2. What are the common symptoms of code B1310 in a Chevrolet?

Symptoms include incorrect outside temperature readings on the dashboard, issues with automatic climate control operation, or no temperature reading at all.

3. What causes the B1310 code on a Chevrolet?

Causes can include a faulty ambient air temperature sensor, damaged wiring or connectors, sensor circuit issues, or in rare cases, a malfunctioning Body Control Module (BCM).

4. Can I drive my Chevrolet with code B1310 active?

Yes, you can drive with the B1310 code, but it may impact climate control functions and provide inaccurate temperature readings.

5. How do I diagnose code B1310 in a Chevrolet?

Start by inspecting the ambient air temperature sensor and its wiring for damage or corrosion. Use a multimeter to test sensor resistance and verify proper voltage at the connector.

6. Where is the ambient air temperature sensor located on a Chevrolet?

The ambient air temperature sensor is typically located near the front grille, behind the bumper, or close to the radiator.

7. How do I fix the B1310 code on my Chevrolet?

Repairs may involve replacing the ambient air temperature sensor, repairing damaged wiring or connectors, or reprogramming the Body Control Module (BCM) if needed.

8. How much does it cost to fix code B1310 in a Chevrolet?

Replacing the ambient air temperature sensor typically costs between $50 and $150, depending on the model and labor rates. Wiring repairs or BCM programming may cost more.

9. Can a bad ambient air temperature sensor affect other systems?

Yes, a faulty sensor can disrupt automatic climate control systems and, in some models, may impact engine performance if temperature data is used in calculations.

10. How can I prevent code B1310 from occurring again in my Chevrolet?

Regularly inspect the ambient air temperature sensor and its wiring for damage, keep the area around the sensor clean, and avoid physical impacts to the front grille or bumper.
