16490/P0106/000262 - Manifold / Barometric Pressure Sensor (G71) / (F96): Implausible Signal

Possible Symptoms

  • Erratic Idle

Possible Causes

  • Wiring and/or Connections from/to Manifold/Barometric Pressure Sensor (G71)/(F96) faulty
  • Leak in Air Intake and/or Exhaust
  • Manifold/Barometric Pressure Sensor (G71)/(F96) faulty
  • Manifold/Barometric Pressure Sensor (G71)/(F96) wrong part installed, see notes.
  • Engine Control Module faulty

Possible Solutions

  • Check Engine Control Module Software Version
    • See Special Notes for Details
  • Check Timing
    • See Special Notes for Details
  • Check Wiring and/or Connections from/to Manifold/Barometric Pressure Sensor (G71)/(F96)
  • Check for Leak in Air Intake and/or Exhaust
  • Check/Replace Manifold/Barometric Pressure Sensor (G71)/(F96)
  • Check/Replace Engine Controle Module

Special Notes

  • On certain smaller Engines we've seen cases where a buggy Engine Control Unit Firmware can cause these fault codes, additionally there are known Problems with the Timing Chain Tensioners which can also result in these fault codes. Please refer to the related TPL/TSB for more instructions.
  • The F96 can be an internal part of the ECM.
  • On some 2.5L engines, there can be a Secondary Air Injection (SAI) sensor, G609. This sensor and the MAP sensor can have the same physical shape and be mixed up. MAP sensors will start with part number "03C" and SAI sensors will start with part number "07C".
