DTC P0107 - Map Sensor

  1. Turn ignition on. Check MAP sensor using scan tool. If approximately zero in. Hg is not indicated, problem is intermittent. Check for poor connections or loose wires at 14-pin connector (on right shock tower), MAP sensor connector, and PCM connector. If approximately zero in. Hg is indicated, turn ignition off and disconnect MAP sensor connector.
  2. Turn ignition on. Check MAP sensor using scan tool. If approximately zero in. Hg is not indicated, replace MAP sensor. If approximately zero in. Hg is indicated, measure voltage between MAP sensor connector terminals No. 1 (VCC1) and 2 (SG1). See Figure . If approximately 5 volts exists, go to step 4). If approximately 5 volts does not exist, repair open in VCC1 circuit between PCM connector terminal D4 and MAP sensor connector terminal No. 1. See WIRING DIAGRAMS  section.
  3. Turn ignition off. Disconnect PCM connector "D". See Figure . Measure resistance between MAP sensor connector terminal No. 3 and ground. See Figure . If continuity exists, repair short in MAP circuit between PCM connector terminal D3 and MAP sensor connector No. 3. See WIRING DIAGRAMS  section. If continuity does not exist, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM.
