Hg is indicated, turn ignition off and disconnect MAP sensor connector.
- 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.
