DTC P0107: MAP Sensor Circuit Low Voltage
1. Turn the ignition switch ON (II).
2. Check the MAP SENSOR in the DATA LIST w i t h the
HDS.
Is about 3 kPa (1.0 in.Hg, 26 mmHg), or 0.23 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 MAP sensor and the PCM.B
3. Turn the ignition switch OFF.
4. Disconnect the MAP sensor 3P connector.
5. Turn the ignition switch ON (II).
6. Check the MAP SENSOR in the DATA LIST w i t h the
HDS.
Is about 3 kPa (1.0 in.Hg, 26 mmHg), or 0.23 V, or
less indicated?
Y E S — G o t o step 9.
N O — G o t o step 7.
7. Measure voltage between MAP sensor 3P
connector terminals No. 1 and No. 3.
