Fuel Economy Drops and Engine Performance Issues in the 2022 Camry
Fuel economy drops and power loss in the 2022 Camry are often caused by minor maintenance issues, but early attention makes all the difference. A few simple checks can restore performance and keep your car running efficiently.
Some 2022 Toyota Camry owners have noticed a decline in fuel economy or sluggish acceleration that wasn’t present when the vehicle was new.
This issue can manifest as lower miles per gallon (MPG), reduced throttle response, or the feeling that the engine is working harder than usual. While occasional fluctuations in mileage are normal, persistent drops can indicate an underlying mechanical or software related problem.
The Camry’s four cylinder and V6 engines are built for long term efficiency, but factors such as driving habits, weather, and maintenance play a big role in overall fuel performance.
If your Camry’s fuel economy has dropped significantly or the engine feels underpowered, several common issues may be to blame. The following table outlines the most frequent causes and their solutions.
Problem | Description | Recommended Fix |
Dirty Air Filter | Restricted airflow causes the engine to burn more fuel to maintain power. | Replace air filter every 15,000 to 20,000 miles |
Faulty Oxygen Sensor | Incorrect readings can cause the engine to run rich and reduce MPG. | Replace oxygen sensor |
Clogged Fuel Injectors | Deposits prevent proper fuel atomization, affecting power delivery. | Use fuel system cleaner or professional injector service |
Low Tire Pressure | Increases rolling resistance, reducing efficiency. | Inflate tires to factory recommended PSI |
Outdated Engine Software | Calibration updates improve throttle mapping and fuel control. | Dealer software reflash |
These issues are relatively easy to fix but can cause noticeable performance loss and reduced efficiency if ignored.
Depending on the cause, repairs to restore fuel efficiency and engine performance can vary widely in cost. Below is a breakdown of common services and their price ranges.
Service | Estimated Cost (Parts + Labor) |
Replace air filter | $40–$80 |
Clean or replace fuel injectors | $150–$300 |
Oxygen sensor replacement | $200–$400 |
Software update or ECU reflash | $100–$200 |
Spark plug replacement | $250–$400 |
For vehicles still under warranty, diagnostic scans and software updates are often free through Toyota dealerships. If multiple systems are affected, a full tune up may be recommended to restore performance.
The best way to maintain strong fuel economy and consistent power is through preventive maintenance. Follow these key tips to keep your Camry running efficiently:
Routine attention to these areas not only improves MPG but also prolongs engine life and reliability.
A minor dip in MPG during cold weather or short trips is normal, but a consistent drop of more than 10 percent often points to a mechanical or sensor issue. If you notice rough idling, weak acceleration, or illuminated warning lights, schedule a diagnostic inspection.
Ignoring power loss symptoms can lead to carbon buildup, catalytic converter damage, or even engine misfires over time. Addressing the issue early is key to avoiding costly repairs and keeping your Camry’s performance at its best.
