DTC P0106 - Manifold Absolute Pressure Sensor Low Vacuum
- Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING CODES
. Start engine and run it at 1000 RPM for one minute with transmission in Park or Neutral. If DTC P0106 is indicated, go to step 3). If DTC P0106 is not indicated, turn ignition off. Turn ignition on. Check Manifold Absolute Pressure (MAP) sensor data using scan tool or PGM tester. If atmospheric pressure is not indicated, replace MAP sensor. If atmospheric pressure is indicated, go to next step.
- Start engine. Raise and hold engine speed to 3000 RPM with transmission in Park or Neutral, until radiator cooling fan comes on. Turn ignition off. Restart engine. Check MAP sensor using scan tool or PGM tester. If MAP sensor reading is 12.0 in. Hg (40.0 kPa) or less one second after starting the engine, MAP sensor is okay at this time. If MAP sensor reading is not as specified one second after starting, replace MAP sensor.
- If DTC P0106 is indicated, check for blocked vacuum port, or restricted or leaking vacuum hose between throttle body and MAP sensor. Repair as necessary. If there is no blockage or leaks, turn ignition off. Turn ignition on. Check MAP sensor using scan tool. If atmospheric pressure is not indicated, replace MAP sensor. If atmospheric pressure is indicated, go to next step.
- Start engine. Raise and hold engine speed to 3000 RPM with transmission in Park or Neutral, until radiator cooling fan comes on. Turn ignition off. Restart engine. Check MAP sensor using scan tool. If MAP sensor reading is 12.0 in. Hg or less within one second after starting, substitute a known-good PCM and recheck for symptom. If MAP sensor reading is 12.0 in. Hg or less one second after starting, replace MAP sensor.
