Checking The Status

Check whether the fault is permanent or intermittent by reading 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). 

The fault is permanent if the signal is incorrect. The fault is intermittent if the signal is correct.
