Trouble Code Number
- Scan tool 36
- General scan tool P0107
- MIL 14

Fault Message
- MAP Sensor Voltage Too Low

Background
- When this code is produced, the MAP sensor voltage has fallen below the minimum acceptable voltage of 0.02 volts
- As in the situation above, the PCM estimates MAP value to allow the engine to run.

Range of Check
- Engine: 400-1500 r/min
- Throttle position sensor output voltage: Less than 1.3V

Set Condition
- MAP sensor output voltage remains less than 0.02 V for 2 seconds.

Probable Cause
- Open 5-volt supply circuit
- Signal circuit shorted to ground
- Sensor failed
- PCM failed
