Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Read off the signal from the manifold absolute pressure (MAP) sensor.
Check that the signal is within its permitted range.

Hint: The normal value (atmospheric pressure at sea level) is approximately 3.6 V at ignition on (open throttle).









Is the signal within its permitted range?
