P2228 / 108-4: Barometric pressure sensor error (Low side)
Behaviour during malfunction (At high altitude):
• Insufficient output
Detection item:
• Sensor / ECU internal circuit short to ground
DTC set preconditions:
• Battery voltage is normal
DTC set parameter:
• Barometric pressure sensor voltage: 1.6 V or less
Engine warning light:
• ON
System action:
• 65 kPa (0.6628 kgf/cm
Recovery from error:
• Diagnostic counter = zero
