Testing & Diagnostics ~282 words
  1. Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle. Check MAP sensor using scan tool. If MAP sensor reading is 30.0 in. Hg or more, go to next step. If MAP sensor reading is less than 30.0 in. Hg, failure is intermittent. System is okay at this time.
  2. Turn ignition off. Disconnect MAP sensor 3-pin connector. Install jumper wire between MAP sensor harness connector terminals No. 2 and No. 3. (Схема №4) Turn ignition on. Check MAP sensor using scan tool. If MAP sensor reading is 30.0 in. Hg or more, go to next step. If MAP sensor reading is less than 30.0 in. Hg, replace MAP sensor.
  3. Turn ignition off. Remove jumper wire from MAP sensor connector. Turn ignition on. Measure voltage between MAP sensor connector terminals No. 1 and No. 2. (Схема №4) If approximately 5 volts exists, turn ignition off and go to next step. If approximately 5 volts exists, go to next step. If approximately 5 volts does not exist, repair open in wire between PCM 16-pin connector D12 and MAP sensor connector terminal No. 2. See the «WIRING DIAGRAMS»(ref-16319) article.
  4. Turn ignition off. Install jumper wire between PCM 16-pin connector terminal D3 and terminal D12. (Схема №2) Turn ignition on. Check MAP sensor using scan tool. If MAP sensor reading is less than 30.0 in. Hg, repair open in wire between MAP sensor and PCM connector terminal D3. If MAP sensor reading is 30.0 in. Hg or more, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM.
