Review AC DELCO GENUINE GM Ambient Temp Sensor Chevy fits IMPALA 2006–2020

The **AC Delco GM 85GRQG Ambient Sensor** is a precision-engineered, high-performance replacement part designed specifically for General Motors vehicles, including the **2006 2020 Chevrolet Impala**, ensuring optimal climate control and passenger comfort. This sensor plays a critical role in the vehicle s HVAC (heating, ventilation, and air conditioning) system by continuously monitoring the ambient air temperature outside the cabin, allowing the system to adjust airflow, temperature, and defrost functions with remarkable accuracy. Crafted with durable, corrosion-resistant materials, the **85GRQG Ambient Sensor** is built to withstand harsh environmental conditions, from extreme heat to freezing temperatures, ensuring long-term reliability and consistent performance. Its sleek, compact design allows for easy installation, fitting seamlessly into the vehicle s existing wiring harness and mounting bracket without the need for modifications. Whether navigating scorching summer days or brisk winter mornings, this sensor ensures that the Impala s climate control operates at peak efficiency, maintaining a comfortable interior environment for both driver and passengers. Ideal for OEM replacement or upgrade projects, the **AC Delco GM 85GRQG Ambient Sensor** delivers the same high-quality performance as the factory-equipped component, backed by the trusted reliability of a brand synonymous with automotive excellence.

### **Pros and Cons of buying a AC Delco GM 85GRQG Ambient Sensor for a 2006-2020 Chevy Impala**

1. **Direct Fitment** This sensor is specifically designed for the 2006-2020 Chevy Impala, ensuring compatibility without modifications. It should plug into the same connector and mount in the same location as the original part.

2. **OEM Quality** As an AC Delco (General Motors brand) part, it meets GM s engineering standards, which generally means reliable performance and durability compared to aftermarket knockoffs.

3. **Prevents HVAC Malfunctions** The ambient sensor detects outside air temperature, allowing the climate control system to adjust heating/cooling more efficiently. A faulty sensor can cause erratic temperature readings, leading to poor comfort or system errors.

4. **Easy Replacement** The sensor is typically located near the windshield or dashboard, making it accessible for a DIY replacement with basic tools.

5. **Warranty Coverage** Purchasing from a reputable seller (e.g., Amazon, AutoZone, or a GM parts dealer) may include a warranty, offering protection against defects.

6. **Cost-Effective Fix** Replacing the sensor is often cheaper than troubleshooting other potential HVAC issues (e.g., faulty climate control module, wiring problems).

---

1. **Potential Counterfeit Risk** Some sellers may offer fake or low-quality parts labeled as AC Delco. Always verify the seller s reputation and check for authenticity (e.g., GM part number matching, packaging quality).

2. **Limited Longevity** While OEM parts are durable, sensors can still fail over time due to environmental exposure (moisture, dust, or electrical wear). Replacement may be needed again in a few years.

3. **Diagnostic Confusion** If the sensor is faulty but symptoms (e.g., incorrect temperature readings) are intermittent, it might be mistaken for another issue (e.g., a bad thermistor in the HVAC system). Proper diagnosis with a scan tool (e.g., OBD-II reader) is recommended before purchasing.

4. **No Performance Upgrade** This is a replacement part, not an upgrade. It will restore functionality but won t improve the HVAC system s efficiency beyond stock specifications.

5. **Installation Challenges** If the sensor is corroded or the connector is damaged, replacement may require additional cleaning or part removal (e.g., dashboard trim). Some users may need to consult a manual or professional help.

6. **Price Variability** Prices can fluctuate based on seller, demand, or region. While generally affordable, budget-conscious buyers might find cheaper aftermarket alternatives (though with less reliability).

The **AC Delco GM 85GRQG ambient sensor** is a **reliable, direct-fit OEM solution** for fixing HVAC temperature sensor issues in your 2006-2020 Chevy Impala. It avoids the guesswork of aftermarket parts and ensures compatibility, making it a **practical choice for DIYers or those who value GM s quality**. However, buyers should **verify authenticity** to avoid counterfeits and **confirm the sensor is indeed faulty** (via diagnostic trouble codes or symptom testing) before purchasing.

For most users, the **pros outweigh the cons**, especially if the sensor is confirmed as the root cause of HVAC problems. If budget is a concern, a **high-quality aftermarket alternative** (e.g., from brands like ACDelco Gold or Bosch) could be considered, but OEM remains the safest bet for long-term reliability.

---

- **Buy from a trusted seller** (e.g., Amazon, AutoZone, or a GM-authorized parts dealer) to ensure authenticity.

- **Check for diagnostic trouble codes** (e.g., P0113, P0115, or P0116) using an OBD-II scanner to confirm the sensor is the issue.

- **Follow installation instructions carefully**, especially if the connector or mounting area is corroded.

- **Consider a backup sensor** if replacing multiple sensors or if the vehicle is frequently driven in extreme climates.

**Final Verdict:** **Purchase the AC Delco GM 85GRQG sensor** if you ve confirmed the sensor is faulty and want a dependable, direct-fit replacement. It s a straightforward fix for a common but frustrating HVAC issue.
