P1532 GMC Code - A/C Evaporator Temperature Sensor Circuit Low Voltage
Quick Answer
The P1532 GMC diagnostic trouble code indicates that there is a low voltage condition in the A/C evaporator temperature sensor circuit. Common causes include Faulty A/C evaporator temperature sensor: The sensor itself may be malfunctioning and sending incorrect voltage readings, Damaged wiring: The wiring connecting the sensor to the control module could be frayed, corroded, or otherwise damaged, leading to a low voltage condition, Faulty control module: The control module that interprets the sensor readings and regulates the A/C system may be faulty, causing a low voltage condition. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P1532 GMC Description
The P1532 GMC diagnostic trouble code indicates that there is a low voltage condition in the A/C evaporator temperature sensor circuit. The A/C evaporator temperature sensor is responsible for monitoring the temperature of the evaporator core in the air conditioning system. This sensor plays a crucial role in regulating the temperature of the air that is blown into the cabin of the vehicle. When the sensor detects a low voltage condition, it means that there is a problem with the circuit that could lead to inaccurate temperature readings and potentially affect the overall performance of the air conditioning system.
Common Causes of P1532 GMC
- Faulty A/C evaporator temperature sensor: The sensor itself may be malfunctioning and sending incorrect voltage readings.
- Damaged wiring: The wiring connecting the sensor to the control module could be frayed, corroded, or otherwise damaged, leading to a low voltage condition.
- Faulty control module: The control module that interprets the sensor readings and regulates the A/C system may be faulty, causing a low voltage condition.
- Electrical issues: Other electrical problems within the vehicle's wiring system could be affecting the voltage in the A/C evaporator temperature sensor circuit.
Symptoms of P1532 GMC
- Inconsistent cooling performance: The air conditioning system may not cool the cabin consistently, leading to discomfort for the occupants.
- Reduced efficiency: The A/C system may take longer to reach the desired temperature, or it may not cool the air as effectively as usual.
- A/C system cycling on and off frequently: The system may cycle on and off more frequently than normal due to inaccurate temperature readings from the sensor.
- Check Engine Light: The illumination of the Check Engine Light on the dashboard could indicate a problem with the A/C evaporator temperature sensor circuit.
How to Fix P1532 GMC
- Diagnose the issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the exact location of the problem within the A/C evaporator temperature sensor circuit.
- Inspect the sensor and wiring: Check the sensor for any signs of damage or malfunction, and inspect the wiring for any visible issues such as corrosion or breaks.
- Replace the sensor: If the sensor is found to be faulty, replace it with a new one that is compatible with the vehicle's make and model.
- Repair or replace damaged wiring: If the wiring is damaged, repair or replace the affected sections to restore proper voltage flow in the circuit.
- Clear the trouble code: After completing the repairs, use the diagnostic scanner to clear the trouble code and reset the Check Engine Light.
Cost to Fix P1532 GMC
The cost of repairing the A/C evaporator temperature sensor circuit low voltage issue can vary depending on the extent of the damage and the specific components that need to be replaced. On average, the cost of parts for this repair could range from $50 to $150, while the labor cost may range from $100 to $200. However, it is important to note that labor rates can vary depending on the location and the repair shop. It is advisable to contact local auto repair shops for a more accurate estimate based on the specific make and model of the vehicle.
