DTC P0106: Map Sensor Performance

NOTE: If DTC P1450 or P1451 is set, diagnose that DTC first.

Connect scan tool to Data Link Connector (DLC). Turn ignition on. Select MAP sensor parameter. Ensure MAP sensor value on scan tool indicates barometric pressure at 100 kPa. Start engine and allow it to reach normal operating temperature. Momentarily increase engine speed to more than 3000 RPM and return to idle. Record MAP sensor value. MAP sensor value should change by more than 33 kPa from key on engine off value of 100 kPa. If MAP sensor value changes as specified, go to next step. If MAP sensor value does not change as specified, go to step 3).
Clear DTCs using scan tool. Operate vehicle within scan tool FREEZE FRAME conditions. If DTC P0106 resets, go to next step. If DTC P0106 does not reset, problem is due to a freeze in the vacuum passage or an intermittent connection. See TESTS W/O CODES article.
Check MAP sensor vacuum source for a leak or restriction. Ensure vacuum source supplies ONLY MAP sensor. If a problem exists, repair as necessary. If a problem does not exist, go to next step.
Connect a hand-held vacuum pump to MAP sensor. Turn ignition on. Observe scan tool display while applying vacuum to MAP sensor. Ensure display changes as specified. See MAP SENSOR VALUES table. If values are not as specified, replace MAP sensor. If values are as specified, check engine compression and ensure false air is not entering intake system. If no problems are found, replace PCM.
