P0106: Manifold absolute pressure sensor performance issue
Drive carefully. Get it checked within a week or two.
Can I drive with P0106?
Yes, but drive carefully and get it checked soon. Manifold pressure readings disagree with throttle position, reducing engine efficiency.
What does P0106 mean?
P0106 stands for Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance.
Symptoms you may notice
- Engine hesitates or jerks when stepping on the gas
- Rough, unsteady idle at stoplights
- Reduced engine power and delayed gear shifts
How much does it cost to fix?
Repair costs for code P0106 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:
- Intake manifold vacuum leak or damaged gasket
- EGR valve stuck open pulling vacuum
- Clogged or carboned MAP sensor nipple
- Failing MAP sensor
What to do next
- Listen for hissing vacuum leaks around intake gaskets and vacuum lines.
- Remove the MAP sensor and inspect the vacuum hole for carbon blockage.
- Verify the throttle body gasket and PCV hose integrity.

About this code
P0106 occurs when the MAP sensor registers pressures outside expected thresholds during deceleration or wide-open throttle. A stuck-open EGR valve or leaking PCV hose often introduces unmetered air that fools the sensor. Diagnosing vacuum leaks usually solves the underlying problem without replacing the sensor.
