Presentation Description

P0106 is the general code for a problem with the MAP circuit having problem of incorrect voltage output range or an issue with engine performance. A break in the flexible air intake duct between the MAF and the intake manifold Often expensive mass airflow sensors and barometric pressure or manifold air pressure sensors are replaced when a simple cleaning then replace the MAP sensor. If all checks are good, then a final test to determine if the ECU is bad must be done feel free to contact us at PartsAvatar, Canada our professional mechanics will help you to diagnose and fix it.

Diagnose P0106 OBD-II Trouble Code of a car: Issue with Manifold Air Pressure and Performance Problem What the P0106 code means P0106 is the general code for a problem with the MAP circuit having problem of incorrect voltage output range or an issue with engine performance. The MAP sensor is an integral part of the fuel injection system and provides signals to the Engine Control Unit ECU for smooth operation and good fuel economy along with proper performance and power. What causes the P0106 code Bad MAP sensor Water/dirt intrusion affecting MAP sensor connector Intermittent open in the reference ground or signal wire for Car’s MAP sensor Intermittent short in the reference ground or signal wire for the MAP sensor Ground problem due to corrosion causing intermittent signal problem A break in the flexible air intake duct between the MAF and the intake manifold

What are the symptoms of the P0106 code 1. Check Engine Light will illuminate. 2. In some cases the engine may be hard starting and/or get poor fuel economy. 3. In some cases noticeably poor engine performance may occur. Common mistakes when diagnosing the P0106 code: Often expensive mass airflow sensors and barometric pressure or manifold air pressure sensors are replaced when a simple cleaning of the MAF “hot wire” could rectify the condition. Corroded wiring and/or connectors have also been reported by technicians. What repairs can fix the P0106 code 1. Verify the code with an OBD-II scanner. Reset the fault codes and perform a road test of the vehicle.

2. If the P0106 code comes back then follow the test procedure. 3. Inspect the vacuum lines and intake hoses for cracked lose or missing parts and electrical connector and wiring. Disconnect the electrical connector and then reinstall to insure a fresh and positive electrical connection. Then check the voltage output on the MAP sensor to see if it is in the correct range. 4. At this point it is best to determine if the MAP sensor is defective and if it has no or incorrect output then replace the MAP sensor. If all checks are good then a final test to determine if the ECU is bad must be done
