Chevy O2 Sensor OEM Pricing and Fitment Table

When a Chevy Silverado or Equinox throws a P0420 or P0430 code, drivers often wonder how much a replacement Oxygen (O2) sensor will cost. Because genuine OEM sensors are crucial for permanently clearing the light and restoring fuel efficiency, we have compiled a pricing and fitment guide for common Chevrolet models.

Quick Answer: How much is an OEM O2 sensor for a Chevy?

A genuine GM OEM or ACDelco Oxygen (O2) sensor for a Chevrolet typically ranges from $60 to $150 per sensor, depending on the model and whether it is an upstream (before catalytic converter) or downstream (after catalytic converter) sensor. Trucks and SUVs with V8 engines will have up to four O2 sensors total.

Why You Cannot "Cheap Out" on Chevy O2 Sensors

You can easily find $25 universal O2 sensors on Amazon. Buying them is the fastest way to guarantee you'll be doing the repair a second time.

X Universal Fitment Issues

Cheap universal sensors require you to splice the old wiring harness onto the new sensor. Splicing sensor wires alters the electrical resistance, which immediately throws a code to the Engine Control Module (ECM).

Direct Fit OEM Value

OEM ACDelco sensors come with the exact factory plug and the correct wire length. They plug in directly and provide the exact voltage the Chevy computer expects. Read more in our GM Check Engine Light & Sensor Replacement Guide.

Frequently Asked Questions

How many O2 sensors does a Chevy Silverado 1500 have?

A typical V8 Chevy Silverado has four O2 sensors: Bank 1 Sensor 1 and Bank 2 Sensor 1 (upstream, before the catalytic converters), and Bank 1 Sensor 2 and Bank 2 Sensor 2 (downstream, after the catalytic converters).

Should I replace all my O2 sensors at the same time?

If one sensor fails due to high mileage (over 100k miles), the others are likely near the end of their lifespan as well. While not strictly required, replacing the upstream sensors in pairs is recommended to keep the engine's fuel trims balanced.

Can a bad O2 sensor cause my Chevy to idle rough?

Yes. A failing upstream O2 sensor provides incorrect oxygen readings to the computer, causing it to inject either too much fuel (running rich) or too little fuel (running lean). This leads to rough idling, hesitation, and poor gas mileage.

What does Bank 1 Sensor 2 mean?

"Bank 1" refers to the side of the engine that houses the #1 cylinder. "Sensor 2" indicates the downstream sensor located after the catalytic converter. This sensor monitors the efficiency of the converter itself.
