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.
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.
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).
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.
