P0106 on Opel: Causes, Symptoms and Fix Cost
Quick Answer
Safe to drive (short-term)
P0106 on a Opel means the MAP (Manifold Absolute Pressure) sensor is sending readings outside the expected range for current engine operating conditions. The ECU uses MAP sensor data to calculate air density and determine fuel delivery, so incorrect readings directly cause poor engine performance and reduced efficiency.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Opel models that log P0106.
Opel Astra
2006-2015
On the turbocharged Astra petrol engines (1.6 Z16LET in the Astra H, 1.4 A14NET in the Astra J) the MAP sensor sits after the turbo. A loose or split charge-air hose can therefore disturb its reading, so check the hoses and clamps between the turbo and the engine before replacing the sensor.

What causes P0106 on a Opel?
Beyond the generic causes listed on the main P0106 page, these are the patterns noted for Opel models:
Loose, split or disconnected charge-air hose between the turbo and the engine
: Opel Astra
Faulty MAP sensor or connector
: Opel Astra
How to diagnose P0106 on a Opel with OBD2
- With the engine off and ignition on, read the MAP sensor value with a scan tool. At sea level, it should read approximately 100 kPa (atmospheric pressure). A significantly different reading suggests a faulty sensor
- Start the engine and observe MAP readings at idle. Typical idle readings are 25-45 kPa. If the reading stays near 100 kPa, check for a disconnected or cracked vacuum hose
- Inspect the vacuum hose from the intake manifold to the MAP sensor. Look for cracks, kinks, or disconnections. Replace if damaged
- Remove the MAP sensor and inspect the sensing port for carbon buildup. Clean with electrical contact cleaner if needed
- Check the MAP sensor wiring and connector for corrosion, moisture, or damage. Repair any wiring issues found
- If the sensor, hose, and wiring are all good, perform a smoke test to check for vacuum leaks elsewhere in the intake system
