The P0106 code on a Chevrolet Cruze refers to a problem with the Manifold Absolute Pressure (MAP) sensor. This sensor measures the intake manifold pressure and sends a signal to the engine control module (ECM) to help determine the correct air/fuel ratio and ignition timing.
P0106 on a Chevrolet Cruze
When the ECM detects that the signal from the MAP sensor is outside of its expected range, it will trigger the P0106 code and illuminate the check engine light.
This could be caused by a variety of issues such as a faulty MAP sensor, a vacuum leak, a clogged or dirty air filter, or a problem with the wiring or connections to the sensor.
To diagnose and fix the issue, you may need to perform some tests on the MAP sensor and related components.
It is recommended to consult a certified mechanic or dealership for proper diagnosis and repair. They may use a scan tool to read the code, perform tests on the sensor and its connections, and replace any faulty components as necessary.

Table: P0106 on a Chevrolet Cruze possible causes and comments for them
| Possible Causes | Comments |
|---|---|
| Faulty MAP sensor | A faulty MAP sensor can cause incorrect readings to be sent to the ECM, which may result in poor engine performance and decreased fuel economy. Replacing the MAP sensor is the most common solution for this issue. |
| Vacuum leak | A vacuum leak can cause an incorrect MAP sensor reading by allowing unmetered air to enter the engine. This can result in rough idling, stalling, and poor performance. The source of the vacuum leak needs to be identified and repaired. |
| Clogged or dirty air filter | A clogged or dirty air filter can restrict airflow to the engine, leading to a reduced MAP reading. This can cause decreased performance and fuel economy. The air filter should be inspected and replaced if necessary. |
| Wiring or connection issues | Wiring or connection issues can cause intermittent or incorrect readings from the MAP sensor. This can be caused by damaged wiring, loose connections, or corrosion. The wiring and connections should be inspected and repaired as necessary. |
| Failed ECM | A failed ECM can cause a variety of issues, including a P0106 code. However, this is a rare occurrence and should only be considered after ruling out other possible causes. If the ECM is found to be faulty, it will need to be replaced and reprogrammed. |
P0106 on a Chevrolet Cruze Tech Note
If you’re experiencing a P0106 code on a Chevrolet Cruze, there are several possible causes that you should investigate. The most common cause is a faulty MAP sensor, which can be diagnosed by testing the sensor with a multimeter or scan tool.
However, before replacing the sensor, you should also check for vacuum leaks, clogged air filters, and wiring or connection issues that could be affecting the MAP reading.
To diagnose a vacuum leak, you can use a smoke machine or propane torch to locate any areas where air is entering the engine. The air filter should also be inspected and replaced if it is dirty or clogged.
Wiring or connection issues can be diagnosed by inspecting the MAP sensor wiring and connections for damage or corrosion. You can also test the wiring with a multimeter to ensure that it is carrying the correct voltage and signal.
If you determine that the MAP sensor is faulty, it should be replaced with a genuine OEM part. After replacing the sensor, you should clear the code and test drive the vehicle to ensure that the issue has been resolved.
If none of these solutions resolve the issue, it is possible that the ECM may be faulty. However, this is a rare occurrence and should only be considered after ruling out all other possible causes. If you suspect a faulty ECM, you should consult with a certified mechanic or dealership for further diagnosis and repair.

| Stalling or hesitation | Check for vacuum leaks or clogged air filters. Clean or replace the air filter as necessary. |
| Increased emissions | Check the MAP sensor, vacuum lines, and wiring for faults. Replace any faulty components as necessary. |
It is important to note that these symptoms can have multiple causes, and proper diagnosis is necessary to determine the underlying issue. If you are experiencing any of these symptoms, it is recommended to consult with a certified mechanic or dealership for proper diagnosis and repair.
P0106 on a Chevrolet Cruze Description
The P0106 code on a Chevrolet Cruze indicates a problem with the Manifold Absolute Pressure (MAP) sensor.
The MAP sensor measures the pressure inside the intake manifold and sends a signal to the engine control module (ECM). This signal helps the ECM determine the appropriate air/fuel ratio and ignition timing for the engine to operate efficiently.
If the ECM detects that the signal from the MAP sensor is outside of its expected range, it will trigger the P0106 code and illuminate the check engine light. This can be caused by a variety of issues, such as a faulty MAP sensor, vacuum leaks, clogged air filters, or wiring or connection issues.
Symptoms of a P0106 code on a Chevrolet Cruze may include rough idle, poor acceleration or performance, stalling or hesitation, reduced fuel economy, and increased emissions.
Proper diagnosis is necessary to determine the underlying cause of the code, and it is recommended to consult with a certified mechanic or dealership for proper diagnosis and repair.
How much does it cost to diagnose and fix the P0106 on a Chevrolet Cruze?
The cost to diagnose and fix the P0106 code on a Chevrolet Cruze can vary depending on several factors, such as the underlying cause of the issue, the severity of the problem, and the mechanic or dealership you choose to work with. Here are some estimated costs:
- Diagnostic fee: Expect to pay around $100 to $150 for a diagnostic test to determine the cause of the P0106 code.
- MAP sensor replacement: The cost of a new MAP sensor can vary from $50 to $150, depending on the brand and model of the sensor.
- Labor costs: The labor cost to replace a MAP sensor can range from $50 to $150, depending on the complexity of the repair and the hourly labor rate of the mechanic or dealership.
Therefore, the total cost to diagnose and fix the P0106 code on a Chevrolet Cruze can range from $200 to $450, depending on the specific circumstances. Keep in mind that these are estimates, and the actual cost may be higher or lower depending on your location and the extent of the repairs required.
How to fix the P0106 on a Chevrolet Cruze?
To fix the P0106 code on a Chevrolet Cruze, you will need to diagnose and repair the underlying issue causing the code. Here are some general steps you can take:
- Use a scan tool to read the code and any associated freeze frame data. This will help you determine what part of the engine control system is malfunctioning.
- Check the MAP sensor to see if it is damaged or faulty. This can be done using a multimeter or a scan tool. If the MAP sensor is not working correctly, it may need to be replaced.
- Inspect the vacuum lines and hoses for any signs of damage or leaks. A vacuum leak can cause incorrect MAP readings, leading to a P0106 code. Repair or replace any damaged vacuum lines or hoses as necessary.
- Check the air filter to see if it is dirty or clogged. A dirty air filter can restrict airflow to the engine, causing incorrect MAP readings. Clean or replace the air filter as necessary.
- Inspect the wiring and connections to the MAP sensor. Loose connections or damaged wiring can cause intermittent or incorrect MAP readings. Repair or replace any damaged wiring or connections as necessary.
- After the underlying issue has been fixed, clear the code with a scan tool and test drive the vehicle to ensure that the issue has been resolved.
If you are not comfortable performing these steps on your own, it is recommended to consult with a certified mechanic or dealership for proper diagnosis and repair. They can use specialized diagnostic equipment to diagnose and repair the issue, and ensure that the repair is done correctly.
