It is typically a problem in the sensor for the MAF throttle body and vacuum leak.

Four Common Causes and Solutions P1101 Chevrolet Malibu

MAF Sensor for Mass Airflow (MAF)

A dirty or dirty mass airflow sensor could result in a P1101 error.
The sensor for mass airflow is located in the filter for air intake. It is simple to clean or replace.
It is recommended that the sensor be cleaned before replacing it, as sensors are usually dirty.

Throttle Body

In the event that the throttle’s body fails or has become filthy, it will emit a P1101.
It is situated in the rear of the engine and is positioned against the firewall. It has the hose for air intake attached.
If the vehicle is filthy, it can be cleaned by cleaning the body of your throttle and an abrasive.
Sometimes, it looks good, but it has dirt that needs to be cleaned.

If the leak is large, the likelihood is that it will be detected. However, more minor leaks are difficult to locate.
A spray bottle could be used to determine whether the idle change when the leak is sprayed in order to aid in locating the source.
A mechanic shop may employ equipment that releases smoking smoke to the systems. The smoke is then released from the leak to help locate the leak.
A typical weakness can be found in the PVC valve that, depending on what Chevy Malibu year it is, could contain two.
Most of the time, when the PVC valve is damaged, the valve will produce the sound of hissing.

Evaluate the O2 Sensors

Use an OBD-II scanner to check for additional error codes or use a voltmeter to check for proper operation. Replace if necessary.

To avoid future run-ins with P1101:

Regularly replace air filters according to your service schedule.
Keep tabs on your MAF sensor’s cleanliness.
Perform routine checks on intake and exhaust systems for signs of wear or leaks.

Conclusion

The Chevrolet Malibu is a great vehicle, but just like any automobile, it can face issues, mainly when it ages.

One of the most common issues is a P1101 OBDII error message.

When the engine check light turns up and an electronic code reader shows an error code P1101, it’s typically an airflow mass MAF, the throttle body, or a leak.

A leak in the air can create problems, with massive leaks typically easy to locate and mall leaks being more complex.

To find leaks that are difficult to locate, mechanics use smoke machines that pump fumes into the system. It then is released from the leak’s location.

The reference voltage can be tested along with leaks in the fuel, pressure of the fuel and vacuum system, fuel trim system if the system isn’t working, and self-testing the range.
