OTe P0107: MAP Sensor Circuit Low Voltage
1. Turn the ignition switch ON (II).
2. Check the MAP with the scan tool.
Is about 101 kPa (760 mmHg, 30 in.Hg)
or
2.9 V
indicated?
YES-Intermittent failure, system is OK a!this time.
Check for poor connections or loose terminals at
the MAP sensor and at the ECM .•
NO-Go to step 3.
3. Turn the ignition switch OFF.
4. Disconnect the MAP sensor 3P connector.
5. Turn the ignition switch ON (II).
6. Measure voltage between MAP sensor 3P
connector terminals No.1 and No.3.

Wire side of female terminals
Is there about 5 V?
YES-Go to step 8.
NO-Go to step 7.
7. Measure voltage between ECM connector
terminals All and A21.

Wire side of female terminals
11-52
Is there about 5 V?
YES-Repair open in the wire between the ECM
(A211 and the MAP sensor .•
NO-Update the ECM if it does not have the latest
software, or substitute a known-good ECM, then
recheck (see page 11-61. If the symptom/indication
goes away with a known-good ECM, replace the
original ECM .•
8. Check the MAP with the scan tool.
Is 2 kPa (15 mmHg, 0.6 in.Hg)
or
less
or
0 V
indicated?
YES-Go to step 9.
NO-Replace the MAP sensor .•
9. Turn the ignition switch OFF.
10. Disconnect ECM connector A (31PI.
11. Check for continuity between MAP sensor
connector terminal No.2 and body ground.

Is there continuity?
YES-Repair short in the wire between the ECM
(A191 and the MAP sensor..
NO-Update the ECM if it does not have the latest
software, or substitute a known-good ECM, then
recheck (see page 11-6). If the symptom/indication
goes away with a known-good ECM, replace the
original ECM .•
