In this post, we will provide you with a comprehensive overview of the p1663 Toyota error code, including its causes, symptoms, and implications. If you’re a Toyota owner or simply curious about automobile diagnostics, this information will help you understand and navigate this particular issue with ease.


  • An outdated engine control module (ECM) software can trigger the p1663 error code, highlighting the need for a software update.
  • A faulty throttle actuator control motor can also be responsible for this issue. Due to wear and tear or internal malfunctions, the motor may fail to function properly, leading to the error code.


  • One of the most common symptoms associated with the p1663 error code is an illuminated check engine light on your Toyota’s dashboard. This serves as a warning sign indicating a potential problem within the throttle actuator control motor or ECM.
  • You may notice reduced engine performance or a lack of power during acceleration. The vehicle might have difficulty reaching high speeds or maintaining a constant speed.
  • Occasionally, the throttle actuator control motor may fail completely, causing the engine to stall or idle roughly.


The p1663 error code, if left unresolved, can have various implications for your Toyota. It can negatively impact fuel efficiency, leading to higher fuel consumption and increased expenses at the pump. Additionally, the compromised engine performance may affect the overall driving experience and potentially put you at risk if the vehicle fails to accelerate adequately in critical situations.

Common Diagnostic Challenges and Solutions for p1663 Toyota

When it comes to diagnosing the p1663 error code in Toyota vehicles, there are a few common challenges that technicians often encounter. Knowing these challenges and their corresponding solutions can save you time and effort during the diagnostic process.

1. Intermittent Check Engine Light: One of the main challenges with the p1663 error code is its intermittent nature. The Check Engine Light (CEL) may come on and go off, making it difficult to pinpoint the exact cause of the issue. To overcome this challenge, it is recommended to use a diagnostic scanner that can capture freeze frame data when the CEL is illuminated, providing valuable information about the conditions in which the error occurred.

2. Faulty PCV Valve: Another common challenge associated with the p1663 error code is a faulty Positive Crankcase Ventilation (PCV) valve. When this valve becomes clogged or stuck, it can lead to improper ventilation and affect engine performance. To address this issue, technicians should inspect the PCV valve and replace it if necessary. Regular maintenance and cleaning of this valve can help prevent future p1663 error codes from occurring.
