P0106 Code: Meaning, Symptoms, Causes & Fix

Overview

Symptoms

• ABS/traction light on
• longer braking intervention
• reduced stability control performance

Common causes

• Sensor drift or delayed actuation affecting manifold absolute pressure/barometric pressure circuit range/performance problem
• Component out of calibration
• Connector pin damage/corrosion or harness stress near related components

How to diagnose P0106

1. Confirm P0106 and capture freeze-frame data with a professional scan tool.
2. Inspect wiring, connectors, and grounds related to manifold absolute pressure/barometric pressure circuit range/performance problem for obvious defects.
3. Compare commanded vs actual values in live data under the same operating condition.
4. Check for related DTCs to identify the root-cause chain before replacing parts.
5. After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P0106

High: This code is high severity because the affected system can directly impact drivability, safety, or catalyst/engine protection.

Can you drive with P0106?

Driving with P0106 should be limited to a short trip for diagnosis/repair. Continued driving can cause expensive secondary damage.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

1. Repair obvious wiring/connector faults first to prevent repeat parts replacement.
2. Address the root fault mode (performance) in the manifold absolute pressure/barometric pressure circuit range/performance problem circuit/system.
3. Apply the required relearn/adaptation procedure if specified by service information.
4. Road-test and verify P0106 remains cleared under the conditions that originally set the code.

Fix options

• Replace out-of-range component and verify live data.
• Clean/repair mechanical restriction where applicable.
• Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$500-$2600

Common mistakes when diagnosing P0106

• Replacing parts without verifying voltage, ground, and signal integrity first.
• Ignoring related stored/pending codes that indicate upstream faults.
• Skipping post-repair verification drive cycle and readiness checks.

P0106 in common vehicles

P0106 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0106?

P0106 is commonly set by performance faults affecting manifold absolute pressure/barometric pressure circuit range/performance problem.

How much does it cost to fix P0106?

For P0106, repair costs are typically $500-$2600 depending on exact root cause, labor rates, and part quality.

Can I clear P0106 without repair?

You can clear P0106 temporarily, but the code usually returns until the underlying fault is corrected.
