Ambient pressure sensor open circuit, or short circuit to ground, or short circuit to supply.
Replace the COO. The atmospheric pressure sensor is integrated in the coordinator and can not be renewed separately.
What you'll see
No driver-visible symptom recorded.
System reaction
• Functions dependent on atmospheric pressure information is degraded. Examples listed below. - EMS will lose the ability for high altitude compensation - instrument cluster display of barometric pressure and boost pressure
Diagnostic depth
Internal fault. Impermissible signal from the internal atmospheric pressure sensor. The sensor voltage level is too low or to high.. The internal atmospheric pressure sensor has an open circuit, or is short circuit to ground, or is short circuit to supply voltage.
• Faulty internal atmospheric pressure sensor unit.
