If you own a 2006 Toyota Corolla, you may have experienced an issue with the transmission. The most common symptom of this problem is the transmission slipping out of gear. This can happen while driving, and it can be extremely dangerous.

Fortunately, there is a fix for this problem. The cause of the transmission slipping is due to a faulty pressure control solenoid. This solenoid controls the amount of fluid that goes to the clutch packs in the transmission.

When it fails, it causes the transmission to slip out of gear. To fix this problem, you will need to replace the pressure control solenoid. This is a relatively easy repair that can be done at home with basic tools.

You can find replacement solenoids online or at your local auto parts store. Be sure to get one that is compatible with your vehicle’s year, make, and model.

How Do I Fix the Code P0171 on My Toyota Corolla?

If you’re getting the P0171 code on your Toyota Corolla, it’s likely due to a lean condition in the engine. This can be caused by a number of things, but most often it’s due to a vacuum leak or an issue with the fuel injectors. To start, check all of the vacuum hoses for any cracks or leaks.

If you find any, replace them and see if that clears up the code. If not, then it’s time to move on to checking the fuel injectors. The first step is to make sure they’re all clean and free of debris.

If they look good, then test their spray pattern using a fuel pressure gauge. If the pattern is uneven or there’s low pressure, then one or more of the injectors needs to be replaced. Once you’ve replaced any faulty parts, reset the engine light and see if the code comes back.

If it does, then there may be another issue at play that will need to be diagnosed and repaired.

What Does P0171 System Too Lean Bank #1 Mean?

If you own a car, you may have experienced a P0171 system too lean bank 1 code. This code is triggered when the computer detects that the air-fuel mixture in the cylinders is too lean. The computer then adjusts the fuel injectors to compensate for this condition.

P0171 is often caused by a dirty or faulty mass airflow sensor (MAF). The MAF measures the amount of air flowing into the engine and tells the computer how much fuel to inject. If it’s not working properly, it can cause the mixture to be too lean.

Other possible causes include a vacuum leak, leaking fuel injectors, or an exhaust leak.

If your car has a P0171 code, there are several things you can try to fix it. Start by cleaning or replacing the MAF sensor.

You can also check for vacuum leaks and repair any that you find. If those don’t work, you may need to replace one or more of your fuel injectors.

How Do I Fix System Too Lean Bank 1 And 2?

If your vehicle is displaying the “system too lean” error, it means that the engine control unit (ECU) has detected an imbalance in the air-to-fuel ratio. This can be caused by a number of factors, including a dirty or damaged mass airflow sensor (MAFS), a vacuum leak, or a problem with the fuel injectors. To fix this issue, you’ll need to diagnose and repair the underlying cause.

Start by checking for any vacuum leaks in the engine bay. If you find one, seal it up with silicone sealant or replace the affected component. Next, check the MAFS for dirt or damage and clean or replace it as necessary.

Finally, have your fuel injectors serviced to rule out any issues there.

What Would Cause One Bank to Run Lean?

There are a number of reasons why a bank might run lean. One reason could be that the bank is trying to save money. Another reason could be that the bank is trying to avoid making risky investments.

Finally, the bank might simply be trying to minimize its losses.


In 2006, Toyota issued a recall for the Corolla due to a problem with the P0171 code. The recall affected approximately 1.3 million vehicles. Toyota issued the recall after receiving reports of the problem from customers.

The recall stated that the problem could cause the engine to stall or fail to start. Toyota advised customers to take their vehicle to a dealer for repair.
