Code P0171 2010 Toyota Camry Description
The P0171 code for a 2010 Toyota Camry indicates that the air/fuel mixture in the engine is running lean on Bank 1. This means that there is an imbalance in the ratio of air to fuel being delivered to the engine, resulting in a mixture that is too lean (too much air, not enough fuel). This can lead to issues with combustion efficiency, causing the engine to run rough, lack power, or even misfire. The engine control module (ECM) monitors the air/fuel mixture and adjusts it accordingly, but if it consistently detects a lean condition, it will trigger the P0171 code.
Common Causes of P0171 2010 Toyota Camry
- Vacuum leaks
- Faulty oxygen sensor
- Dirty or clogged fuel injectors
- Malfunctioning mass airflow sensor
- Fuel pump issues
Symptoms of P0171 2010 Toyota Camry
- Rough idle
- Decreased fuel efficiency
- Engine hesitation or stalling
- Check Engine Light illuminated
- Increased emissions
How to Fix P0171 2010 Toyota Camry
- Inspect and repair any vacuum leaks in the intake system.

I drove my 2010 4 cyl Camry from Indiana to fla.100 miles out it started jerking intermittently and slowing down in power I got off highway code said po 171 so I replaced MA's airflow got back on highway and drove 5 to 10 miles started doing same thing. took it to shop they tested everything .couldn't fine the problem.now when I drive the car about 30 miles at speeds of 55 or so it starts doing same thing.what's wrong

There are some test that needs to be done to determine exactly what the problem is, but the most common problem is the "Air/Fuel Ratio Sensor". Before you replace any more parts, check the hose (duct) that goes from the air filter box to the intake. Sometimes the hose gets cracked and cause the same symptoms.
