DTC P0102: MAF Sensor Circuit Low Voltage
1. Turn the ignition switch ON (II), and wait 2 seconds.
2. Check the MAF SENSOR in the DATA LIST w i t h the
HDS.
Is about 0 gm/s or 0.1 V or less indicated?
Y E S — G o t o step 3.
NO—Intermittent failure, system is OK at this t i m e .
Check for poor connections or loose terminals at
the MAF sensor and the PCM. •
3. Check the No. 18 ACG (15 A) fuse in the under-dash

Is the fuse OK ?
Y E S — G o t o step 4.
NO—Repair short in the w i r e between the MAF
