The most common causes are: Vacuum leak in the intake manifold or hoses; Clogged or disconnected MAP sensor vacuum hose; Carbon buildup blocking the MAP sensor port; Failing MAP sensor; Restricted exhaust raising manifold pressure.

How much does it cost to fix P0106?

Typical repairs range from $20–$100 for replace vacuum hose up to $100–$300 for replace map sensor. Costs vary by vehicle and region.

P0106 – Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

What does P0106 mean?

The manifold absolute pressure (MAP) sensor is producing a reading that is electrically valid but inconsistent with engine operating conditions. The MAP sensor measures intake manifold vacuum/pressure so the computer can calculate engine load.

SystemP — Powertrain

TypeGeneric (standardized SAE / OBD-II code — same meaning across most manufacturers)

SubsystemFuel and air metering

Common symptoms

Check engine light on
Rough idle and hesitation
Poor acceleration
Increased fuel consumption
Possible black smoke

How to diagnose

1Inspect the MAP sensor vacuum hose for cracks, disconnection, or blockage.
2Remove the sensor and check its port for carbon buildup.
3Smoke-test the intake for vacuum leaks.
4Compare live MAP readings against barometric pressure with the key on and engine off — they should match closely.
5Watch MAP at idle and under acceleration; readings should change smoothly and predictably.

Incorrect load calculation causes wrong fuel and timing decisions, hurting drivability and economy.

Common fixes and estimated costs

Repair	Estimated cost
Replace vacuum hose	$20–$100
Clean MAP sensor and port	$50–$150
Repair vacuum leak	$100–$500
Replace MAP sensor	$100–$300

Costs are rough US estimates including parts and labor. Actual pricing varies significantly by vehicle, region, and shop rates.

Good to know

With the key on and the engine off, the MAP sensor should read close to atmospheric pressure. That quick check separates a failed sensor from a vacuum problem in about a minute.
