What is the P0106 fault code? What does it signify?
Engine performance and excessive exhaust emissions can indicate many problems. Your OBD-II scanner may detect a P0106 code after testing. This could indicate that your barometric air pressure (BARO) or manifold absolute (MAP) sensors are faulty.
Description of trouble code P0106 is included with it “Manifold Absolute Pressure / Barometric pressure (BARO) Sensor Circuit Range/Performance Issue” . This code is activated when the Powertrain Control Module / ECM receives an erratic reading from the MAP/BARO sensor. An engine load will affect the signal strength, so a functioning MAP sensor should send a signal of between 1 and 4 volts to its PCM. If the PCM detects that MAP/BARO sensor signals are above or below a preset threshold for a given time, it will report error code P0106.
Chevrolet (especially Cruze), Ford, Hyundai, Ford, Infiniti and Volkswagen are all affected by P0106.
The MAP sensor monitors the intake manifold pressure. The BARO sensor measures atmospheric tension. Most vehicles have both the MAP sensor or the BARO sensor combined into one sensor.
The MAP sensor data is used by the PCM to calculate engine load, fuel delivery and, in some cases, ignition timing and EGR operation. Some vehicles do not include a MAP sensors. The fuel delivery is calculated using the Mass Air Flow (MAF), sensor. You can also have vehicles that rely solely upon a MAF sensor but have a MAP sensors as a backup.
Note: Range/Performance-related fault codes are created when information from sensors is not within the range that the PCM expects to see when current engine RPM/speed calculations take place.
Other fault codes for MAP sensors include P0105 and P0107.
Although all MAP sensors are located within the intake manifold, there are some differences in design between different manufacturers. The image below shows where the MAP sensors are located on four-cylinder engines.
What are the Possible Reasons for P0106 Fault Codes?
The most common issues that could trigger a code P0106 are:
- – Vacuum leaks, cracked or loose connections to air inlet pipe.
- – Electric fault (circuit opened, short circuit or high resistance).
- – Damaged or worn cables connections
- – Defective MAP/BARO sensor
- – EGR system malfunction
- – In rare cases, defective control module
Note: There may be other codes in addition to P0106. The common causes and symptoms could differ from the ones listed here. The following issues can trigger fault code P0106:
- – A prolonged or severe misfire on one or more cylinders
- – Clogged catalytic converter(s).
- – Defective throttle positioning sensor
- – Defective mass flow sensor
- – Defective exhaust gaz recirculation device
- – Defective Idle Air Control Motor
What are the symptoms for P0106 Malfunction Codes?
- – Illumination for check engine lights
- – An increase in exhaust emissions values
- – Increased fuel use
- – Engine performance and acceleration problems with sudden accelerations.
- Engine Stalling and Stalling
- – Idle irregularity
- – The exhaust emits black smoke
How do I fix the P0106 fault code?
- Road test should be performed to verify that the code is returning.
- If the code is returned, vacuum lines and connections to air inlet pipes should be checked.
- – Check cables and circuits, loose connections and corroded cables should be repaired.
- When the engine is in use, it should be run a voltage test on the sensor. Normally, the idle voltage is 1 to 1.5 volts. Full throttle usually is around 4.5 V.
- – If none of the above actions have resolved the problem, replace your MAP sensor.
- – If neither of these failed, the ECU should also be tested.
How Serious Is the P0106 Fault Coding?
Fault code P0106 is a fault code that causes an engine to run poorly. This requires immediate attention. It is important to diagnose the problem as soon as you can. An MAP sensor problem may cause excessive fuel consumption and rough running. It can also make it difficult to start under certain conditions. Further damage could occur if the vehicle is driven in this way.
