In order to do this, simply unhook the positive terminal from your car battery for a minimum of 10 minutes. This can be easily done through a good old hard reset. If you do not have the equipment to clear the error code, you will have to do it manually. If you need to replace the MAF sensor, you will find that the light will not automatically go off. When the P0102 error appears, you will get a check engine light on the dash. How Do you Reset Check Engine Light After Replacing MAF Sensor? The good thing is that all the possible causes can be addressed inexpensively. In other scenarios, you will need to repair the affected part. In the most basic of cases, simply cleaning the affected part will enable you to sort the problem out without much effort. To fix the problem, you will need to repair or replace the part that is the cause of the restriction. IF you haven’t caught on already, the P0102 code is triggered by insufficient or restricted airflow to the engine. How do I fix code P0102 on a Chevrolet Silverado? This, in particular, will prevent the sensor from giving accurate readings leading to poor performance and ultimately the P0102 code being shown. If it is dirty, it needs to be replaced.Ĭarbon build-up on the MAF Sensor screen is another possible cause of this particular problem. The air filter is an important part of the whole air intake mechanism and if it is dirty, the air intake is throttled leading to insufficient amounts of air coming in.Ī simple test to see whether the air filter is clean is to take it out and hold it against the light. In such a scenario, the sensor needs to be replaced immediately.Ī dirty air filter will also lead to a P0102 code. When the sensor is faulty and not working as it should, the results are pretty obvious. The next possible cause is a faulty MAF sensor. This scenario actually leads to poor fuel economy. When the voltage being sent to the MAF sensor is too low, the sensor will send inadequate amounts of air into the combustion chamber leading to low power as the air/gas mix will be disproportionate. What happens is that when you press the accelerator pedal, the MAF works with the throttle position sensor to regulate how much gas and air is released into the engine. The first possible cause is low voltage going to the MAF sensor. So, what exactly causes the code? Well, there are several possible causes and if you want to solve the problem, you need to check through all of these possible causes. If the sensor is impeded in one way or another from regulating the right amount of air into the engine, the result will be reduced power output. When you press on the throttle, more air should be released into the engine for the combustion process. This sensor is responsible for regulating the amount of air that is released into your engine. When you see this code, it means that there is something wrong with your Mass Airflow sensor. When your mechanic runs diagnostics, they get the P0102 code. You are driving your Silverado and notice that it starts being jerky with very little power output regardless of the pressure you put on the throttle. Conclusion What is a P0102 Code on a Chevy Silverado?
