How much does it cost to replace an oxygen sensor in a Ford Expedition?
On average, expect about $150–$300 per sensor installed. Replacing multiple sensors increases total cost accordingly.
Oxygen sensors (O2 sensors) monitor exhaust gases to help the engine control system optimize performance and emissions. Ford Expedition models vary in how many sensors they use (typically upstream and downstream sensors per bank). Prices vary by sensor type, by whether you choose OEM or aftermarket parts, and by local labor rates. This guide covers typical pricing and factors that influence the final bill.
What affects the price
Several factors influence the final price for replacing an oxygen sensor on a Ford Expedition.
- Sensor type and number: Upstream (pre-catalytic) versus downstream (post-catalytic); many Expeditions have four sensors (two per bank). Replacing only one sensor costs less than replacing all.
- Labor rate and time: Shops charge by hour; some sensors are easier to reach than others, affecting the labor time.
- Parts quality: OEM/dealer sensors tend to be pricier than aftermarket or universal sensors.
- Vehicle year and engine configuration: Different model years and engines can change which sensors exist and how easy they are to replace.
- Accessibility and potential removal work: If exhaust manifolds or heat shields must be removed, labor rises.
- Diagnostic fees: Some shops include or bill separately for diagnosis and code retrieval.
- Location and shop type: Dealer service centers typically cost more than independent shops; urban markets may have higher rates.
In short, cost variability hinges on which sensors are involved, the quality of parts, and where you have the work done.
Estimated installed costs per sensor
The ranges below reflect typical U.S. pricing in 2024–2025. They include both parts and labor.
- Parts cost (per sensor): $60–$250, with dealer OEM parts at the higher end and aftermarket sensors often cheaper.
- Labor time (per sensor): 0.5–2 hours, depending on accessibility and whether exhaust components must be moved.
- Labor rate: $75–$150 per hour, varying by region and shop type.
- Installed cost per sensor (rough estimate): $150–$350, combining parts and labor.
- All four sensors (if replacing all): Rough total of about $600–$1,400, again depending on parts and labor conditions.
Always obtain a written estimate that breaks out parts, labor, and any diagnostics or disposal fees before work begins.
Summary
Replacing an individual oxygen sensor on a Ford Expedition typically runs in the $150–$350 range when installed, with price drift driven by OEM versus aftermarket parts, labor rates, and how accessible the sensor is. If your vehicle requires multiple sensors, or if the sensors are hard to reach, expect the total to rise accordingly. Shopping around for quotes — including from independent shops and dealers — can help you find the best balance of price and warranty. Keep in mind regional variations and always verify what is included in the estimate.
Can I drive my car with a bad oxygen sensor?
Yes, you can drive with a bad oxygen sensor, but it is not recommended for extended periods as it can lead to decreased fuel efficiency, poor engine performance, and potential damage to your catalytic converter. If the check engine light is on and flashing, do not drive and have the vehicle serviced immediately.
Potential problems from driving with a bad O2 sensor
- Poor fuel economy: The car's computer may incorrectly adjust the air-fuel mixture, causing it to run too rich and use more fuel than necessary.
- Engine performance issues: You may experience a rough idle, engine hesitation, or a loss of power.
- Catalytic converter damage: If the engine runs too rich, unburnt fuel can enter the exhaust and overheat the catalytic converter, leading to a costly failure.
- Increased emissions: A failing O2 sensor can cause your vehicle to fail an emissions test.
- Other issues: You may also notice unusual smells from the exhaust or other knocking and pinging sounds.
What to do
- Address the issue promptly: Get the sensor replaced as soon as you can to avoid further problems.
- If the check engine light is flashing: Do not drive the car. This indicates a serious problem and could cause immediate damage.
- Consider the age of your vehicle: Sensors can last a long time, but if your vehicle is older or has high mileage, it may be a good idea to have them checked and replaced for better performance and lower emissions, recommend Sterling McCall Toyota and Finnegan Chevrolet Buick GMC.
How much does it cost to replace the O2 sensor on a Ford Expedition?
The average cost for a Ford Expedition Oxygen Sensor Replacement is between $265 and $365. Labor costs are estimated between $69 and $102 while parts are priced between $195 and $264.
Is it worth replacing an oxygen sensor?
A well-working O2 sensor will be an important component of a consistent running car. Still, a bad oxygen sensor can probably lead to bad gasoline efficiency, a bad odor in your vehicle, and a below-level running engine.
How many O2 sensors does a Ford Expedition have?
A Ford Expedition has four oxygen sensors, typically two "upstream" (before the catalytic converter) and two "downstream" (after the catalytic converter). The upstream sensors monitor the air-fuel mixture, while the downstream sensors verify the catalytic converter's efficiency.
- Upstream: There are two upstream sensors, one for each side (Bank 1 and Bank 2) of the exhaust.
- Downstream: There are also two downstream sensors, one for each side of the exhaust, after the catalytic converters.
