* Location: Labor rates vary significantly by region and shop. A big city shop will generally charge more than a smaller town mechanic.
* Which sensor: The Impala has multiple oxygen sensors (usually one before and one after the catalytic converter). The sensor location affects accessibility and therefore labor time. Replacing the sensor after the converter is often more involved.
* Parts cost: The price of the oxygen sensor itself depends on the brand (OEM vs. aftermarket) and the retailer. A genuine GM part will be more expensive than a high-quality aftermarket equivalent.
* Shop type: Dealerships typically charge the most, followed by independent repair shops, and then possibly the least expensive option being a DIY repair.
Rough Estimates:
* Parts: $30 - $150 (depending on the sensor and where you buy it).
* Labor: $50 - $150 (depending on location and sensor location).
Total Estimated Cost: Expect to pay anywhere from $80 to $300. This is a wide range, and getting specific quotes from local mechanics or auto parts stores is recommended to get an accurate estimate for your situation.
Before you get any work done:
* Get multiple quotes: Call several shops to compare pricing.
* Specify which sensor needs replacing: Knowing the exact location of the faulty sensor will help get a more accurate quote.
* Inquire about the brand of sensor: Ask if they're using an OEM or aftermarket part, and get the brand name if it's aftermarket. This allows you to check the reputation of the part independently.
By being informed and getting quotes, you can avoid paying too much for the oxygen sensor replacement.
