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.
• When checking for leaks in the Air Intake system:
  • Make sure to closely check hard plastic brake booster lines near check valves and barbed adapters where cracks are most frequently found.
  • Make sure the PCV system is not malfunctioning and that the dipstick tube (when applicable) is not cracked or leaking at the junction to the cylinder block.

2.5L Gasoline specific notes

• Measuring block 201.3 appears to contain the F96 ECM Baro pressure sensor in the CBTA 2.5L in addition to older MAF equipped 2.5L engines such as the BGP. ST?ID=79232
• 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".
• When found in NAR (North American Region) 2011-2014 Jetta, Golf, Passat and New Beetle vehicles with 2.5L engine codes CBTA and CBUA see TSB 01-14-23 -or- TPI 2034012. When applicable, DTCs P050A, P0507 and P0106 are resolved after flash updating the Engine controller.

1.4T Gasoline specific notes

• When this DTC is stored in North American Region (NAR) vehicles with the 1.4T make sure the software level in the 01-Engine control module is up to date. It may be stored in conjunction with P0237. Internal ref to ST?ID=108190
