  1. Turn the ignition switch to ON (II).
  1. Check the MAP SENSOR in the DATA LIST with the HDS.
Is about 3 kPa (26 mmHg, 1.0 in.Hg), or 0.23 V or less indicated?
YES -
Go to Step 3 .
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM.■
