Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Manifold Absolute Pressure - Barometric Pressure Correlation.

Severity

moderateCan drive, but performance issues may occur.

Summary

P0069 indicates a correlation issue between the Manifold Absolute Pressure (MAP) sensor and Barometric Pressure (BARO) sensor in your vehicle's engine management system.

Symptoms

  • Illuminated check engine light
  • Surging
  • Rough idle
  • Detonation
  • Loss of power

Common Causes

  • Faulty MAP sensor
