This may indicate a dirty filter or a defective mass air flow sensor. All this means is that the PCM is showing an error. Here’s what to expect if you’re seeing a P0113 error code.

This is the most expensive possibility, but normally a faulty PCM will be doing more than just misreading the air temperature.Ĭommon Symptoms Associated With the P0113 Code

This is less common, but it can cause your car to try to draw too much air, which can be the root cause of an overheated air intake. It can even be the root cause of a damaged sensor. Short circuits or stripped wires can cause all kinds of things to go wrong with your electrical systems. This will cause your intake to overheat but is relatively easy to fix. Here are some of the things that could be causing your IAT sensor to return a high voltage. These include issues with the air to fuel ratio and the ignition spark timing and can lead to low gas mileage and high emissions. However, assuming the intake is indeed too hot, you can run into a number of issues with your car. This isn’t necessarily the case we’ll talk about other possible issues in a second. If your IAT sensor is reading too high of a voltage, your PCM will think that your air intake is excessively hot. What Does the P0113 Code Mean For My Car?

If your resistor is returning the full five volts, it triggers the P0113 error code. So a cold resistor will lower the voltage more than a hot one, and a sufficiently hot resistor won’t lower the voltage at all. This works because a resistor loses resistance as it heats up. The PCM sends it a continuous current of five volts, and monitors how much voltage it gets back. If your PCM is returning a P0113 error code, it means that your Intake Air Temperature (IAT) sensor is reading at too high of a voltage. For more information on what your car’s computer does, check out our previous article explaining automotive computers. It also controls a variety of other automotive systems. Its job is to regulate your fuel to air ratio, manage your transmission, control emissions, and maximize your fuel efficiency. The PCM is basically the brain of your car and monitors a wide variety of systems. The P0113 code is one of many codes that are created by your car’s Powertrain Control Module (PCM).

– Scanning tool for reading IAT sensor output.

– Temperature gauge for measuring air intake and coolant temperature.

– Flashlight for looking under the hood.

Tools Needed For Diagnosis and Repairīefore we go any further, here are the tools you’ll need to properly diagnose and fix a P0113 error code. We’ll explain what the P0113 error code means, potential causes, and what you can do to fix it. So you’ve read your error code and it says “P0113”. Of course, if you or a friend own a code reader, you can plug into the car and find out what error is causing the issue. Since any of these issues can cause your “ check engine” light to come on, it’s no surprise that that particular light causes a lot of frustration among motorists. Modern cars contain dozens of sensors that monitor everything from radiator pressure to engine temperature to the amount of CO2 in your emissions. On the right is an AEM 7-bar sensor, with a more universal threaded end and a ton of resolution.P0113 Code: Everything You Need To Know On the left is a FAST GM-style sensor, which is popular in the aftermarket, as evidenced by the fact that companies other than GM make GM-style. MAP sensors come in all shapes and sizes. The safe/limp mode is not optimal for long-term driving, and your engine needs the MAF sensor to run properly. Should You Drive Without The MAF Sensor? While unplugging the MAF sensor to test whether it’s the cause of your problems is fine, you should not continue driving without it. Where is the mass air flow sensor on a 2004 GMC Envoy? (video)Ĭan you drive a car without a mass air flow sensor? via Where is the mass airflow sensor on a 2005 Trailblazer? (video) Because it is in the intake tract, A MAF sensor will also have its own housing (usually plastic) to hold it in place. What are some differences between a MAP and MAF sensor? While a MAF sensor is always located before the throttle body, a MAP sensor can usually be found attached to the intake manifold. via Is a mass air flow sensor the same as a MAP sensor? How do you change the MAP sensor on a 2004 Trailblazer? (video)ĭoes a 2004 Chevy Trailblazer have a mass air flow sensor?Ģ004 Chevrolet Trailblazer Mass Air Flow Sensor – from $84.99+ |.
