If you own a 2008 or newer Chevy truck with a 5.3 liter engine, you may have experienced the check engine light and reduced power mode issue. In this video, we’ll walk you through a common problem with Chevy trucks and demonstrate how to fix it. The specific issue involves the throttle position sensors on the electronic throttle body, which can cause the code P2135 to appear.
Diagnosing the Problem
The code P2135 indicates a problem with the throttle position sensors. As explained in the video, the data from the throttle position sensors may show a variance that triggers the code. The solution to this problem involves replacing the throttle body cover and ensuring that the sensors are properly aligned.
Step-by-Step Guide to Fixing the Issue
The video provides a detailed walkthrough of the process, from removing the throttle body to cleaning it and installing the new throttle position sensor cover. It also mentions the importance of reprogramming the ECM with the latest software calibration after completing the repair.
Final Testing and Results
After completing the repair, the video demonstrates how to clear the codes and perform a functional test to ensure that the new throttle position sensor is working correctly. The engine is started, and the data from the sensor is monitored to verify its performance.
Conclusion
The video concludes with a summary of the repair process and reiterates the importance of having the PCM reflashed by a professional. The host encourages viewers to subscribe for more helpful content and expresses confidence in the effectiveness of the demonstrated solution for the Chevy truck issue.
If you encounter a similar problem with your Chevy truck, this video can serve as a helpful guide for resolving it. With clear explanations and practical demonstrations, the repair process is made more accessible to truck owners facing this common issue.
What is the issue with the 2009 Chevy truck with the 5.3 liter engine?
The check engine light came on and the reduced power mode was activated, causing the vehicle to only crawl along. The error code P2135 is a common problem for Chevy trucks from 2008 onwards, usually related to throttle position sensors on the electronic throttle body.
How can the problem with the throttle position sensors be fixed?
GM has released a kit to repair the throttle position sensors, which is cheaper than replacing the whole throttle body. The process involves removing the throttle body, cleaning the inside, replacing the throttle position sensor kit, ensuring the PCM has a software update, and reprogramming the ECM with the latest software calibration.
What are the steps to replace the throttle position sensor kit?
The steps involve removing the throttle body cover, ensuring the gear is not impacted, discarding the old cover gasket and terminals, installing the new throttle position sensor cover, and testing the TP sensor data to verify proper functioning.
How to relearn idle after replacing the throttle position sensor kit?
There is a process to reset the minimum TPMS and airflow in the ECM, and the vehicle will relearn on its own. Additionally, a scan tool can perform the function test and module setup for idle learn reset.
How can the video be helpful for viewers?
The video aims to provide insight into diagnosing and fixing the P2135 code related to throttle position sensors. It offers a step-by-step guide for replacing the throttle position sensor kit and reprogramming the ECM, with the intention of helping viewers understand the process and gain confidence in handling similar issues with their vehicles.
