Solution Toyota Auto Trouble code P1010

If you’re a Toyota owner who’s been experiencing trouble with the Check Engine Light, then this blog post is for you. We’ll be discussing the Auto Trouble code P1010 and how to identify and fix it. So, let’s get started!

What is Toyota Trouble Code P1010?

Toyota Trouble Code P1010 is a trouble code that relates to the Exhaust Gas Recirculation Sensor B Circuit High. This code can be triggered by an injector circuit malfunction, an open or short in the OCV circuit, or a faulty MAF sensor. Symptoms of this code include decreased fuel economy, engine misfires, stalling, and reduced power output. If left unchecked, this code can cause further damage to the vehicle’s engine and fuel system.

Identifying the Symptoms of Toyota Trouble Code P1010

Toyota trouble code P1010 is a diagnostic trouble code (DTC) which points to an issue with the vehicle’s throttle body. Identifying the symptoms of this trouble code can help you determine if this is the underlying cause of any issues you may be experiencing with your Toyota. Common symptoms of P1010 include reduced engine power, stalling, hesitation or jerking when accelerating, poor fuel economy, and a check engine light. If you are experiencing any of these symptoms it is best to diagnose the issue as soon as possible to avoid further damage to your vehicle.

Potential Causes of Toyota Trouble Code P1010

Toyota Trouble Code P1010 can be caused by a number of things, including a faulty throttle body sensor, a faulty mass air flow sensor, a broken oxygen sensor, or a busted catalytic converter. The PCM counts the number of times vehicle speed transitions from 0 to 1 mph and if the PCM detects an open or short in the OCV circuit, it will throw the P1010 code. This code can be especially costly as replacing a broken oxygen sensor can lead to a busted catalytic converter which can cost upwards of $1,300.

Diagnosing Toyota Trouble Code P1010

If you’re experiencing symptoms of Trouble Code P1010, it’s important to diagnose the underlying cause. To diagnose this code, you’ll first need to connect a scanner to your Toyota’s onboard diagnostic port. Once the scanner is connected, it can read the stored trouble codes and provide more detailed information about the cause. If the code is P1010, it’s likely related to one of the following potential causes: an open or short in the OCV circuit, an insufficient pressure change when the A/C clutch engages, or a VVT-supply voltage control motor high input.

Once you’ve identified the cause of the Trouble Code P1010, you can move forward with repairing it. In most cases, a DIYer can make the necessary repairs. However, some repairs may require a professional mechanic. In any case, it’s important to test your vehicle after repairs are completed and clear any stored trouble codes before taking your Toyota back on the road.

DIY Solutions for Toyotas With Trouble Code P1010

If you suspect that your Toyota may have trouble code P1010, there are a few DIY solutions that you can try before taking your car to a mechanic. One of the most common solutions is to replace the air conditioning pressure sensor (ACP). This sensor is responsible for monitoring the pressure of the air conditioning system, and if it doesn’t register a change in pressure each time the A/C clutch engages, then the PCM will throw a P1010 code. Replacing this sensor is relatively easy and only requires a few tools.

Another potential solution is to replace the throttle body sensor. This sensor monitors the pressure of the air entering the engine and is responsible for controlling engine idle speed. If this sensor has become faulty, then it can cause your Toyota to throw a P1010 code. Replacing this sensor will require a few tools and some basic understanding of car mechanics, but is still relatively simple.

Finally, you may need to replace your mass air flow (MAF) sensor. This sensor measures the amount of air entering the engine and helps regulate fuel delivery. If this sensor is malfunctioning, then it can cause your Toyota to throw a P1010 code. Replacing this sensor requires some knowledge of car mechanics, but can usually be done with minimal tools.

Replacing Faulty Sensors or Components

When diagnosing and solving a Toyota trouble code P1010, it is important to identify the faulty sensor or component that is causing the issue. Depending on the particular model and year of your Toyota, some of the most common components to check are the air conditioning pressure sensor (ACP), mass air flow sensor (MAF), and the throttle body sensor. If any of these sensors are found to be faulty, they must be replaced in order for the engine light to be reset and for the Toyota to run properly.

Throttle Body Sensor Replacement

If you’re experiencing symptoms associated with Toyota Trouble Code P1010, particularly a delay in acceleration or engine stalling, then you may need to replace the throttle body sensor. The throttle body is an important component of your vehicle’s fuel system, as it regulates the amount of air that passes into your engine and helps determine the speed of acceleration. To replace the throttle body sensor, you’ll need to remove the air intake assembly, the wiring harness, and the throttle body itself. Once you have access to the sensor, you’ll need to disconnect it from the wiring harness and install a new one. Once it’s secured in place, you can reassemble the air intake assembly, attach the wiring harness, and start your engine to test for proper operation.

Mass Air Flow Sensor Replacement

If the Mass Air Flow (MAF) Sensor is determined to be the cause of Toyota trouble code P1010, it must be replaced. The MAF sensor measures the amount of air entering the engine, and when it fails, it can cause a variety of engine issues, as well as a decrease in fuel efficiency. The MAF sensor is located inside the air filter housing and is easily replaced with a few basic tools. Before replacing the MAF sensor, the air filter should be replaced and the MAF sensor should be cleaned with compressed air. After the new MAF sensor is installed, the engine light should be reset to ensure that all of the codes are cleared from memory.

Clearing the Engine Light After Repairs

After repairs are made to the engine, it is important to clear the trouble code from memory. This can be done with a scan tool or code reader which can be purchased for around $50-100. Once the code is cleared, the engine light will no longer be illuminated. However, it is important to note that if the same conditions are present that caused the code to appear in the first place, then the engine light will come back on. Therefore, it is important to make sure that all repairs are made correctly and any faulty sensors or components are replaced with new ones. Additionally, it is important to test the vehicle after repairs are completed to ensure that the issue has been resolved and there are no other underlying problems.

Professional Repair Advice for Toyota Trouble Code P1010

If you are having trouble diagnosing and repairing a Toyota with trouble code P1010, it is important to seek the advice of a professional. A qualified mechanic will be able to diagnose the exact cause of the problem and determine the necessary repairs. They can also test the system after repairs are completed to ensure that the problem has been resolved. Professional repair advice for Toyota trouble code P1010 will help ensure that your car runs smoothly and safely.

Testing After Repairs Are Completed

Testing the vehicle after repairs are completed is the final step in resolving Toyota Trouble Code P1010. Using a diagnostic scan tool, check to see if the trouble code has been successfully cleared. If the code is still present, then further diagnostics may be needed. After repairs are completed, it is best to take the vehicle for a test drive to ensure that all systems are working properly. It is important to monitor the vehicle during the test drive for any potential issues that may arise. If any issues are found, it is best to return the vehicle for further diagnostics and repairs.


When it comes to resolving Toyota trouble code P1010, it’s important to have a solid understanding of all the potential causes, symptoms, and solutions. By diagnosing and testing the vehicle accurately, you can ensure that any faulty sensors or components are replaced as needed and that the engine light is cleared after repairs are completed. If you’re unsure of how to best diagnose and repair your Toyota vehicle, then it’s best to seek out professional help. A qualified technician can provide the expertise needed to ensure that the repair job is done correctly and that your vehicle is running smoothly once again.
