» If the displayed value is equal to the setpoint value:
–
Delete the fault code.
–
Make a test ride.
–
Read out the fault code.
» If the displayed value is below the setpoint value:
–
Check the next possible cause:
Manifold absolute pressure sensor - signal line has a short circuit to sensor ground (
p. 168)
Manifold absolute pressure sensor - signal line has a short circuit to sensor ground
Condition
Th e diagnostic tool is disconnected.
The EFI control unit is disconnected.
The manifold absolute pressure sensor is disconnected.
