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. If MAP sensor value changes more than 33 kPa from engine off to engine idle, 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 FREEZE FRAME conditions. If DTC P0106 resets, go to next step. If DTC P0106 does not reset, check for an intermittent problem. See appropriate TESTS W/O CODES article.
Check MAP sensor vacuum source for a leak or restriction. Ensure vacuum source supplies MAP sensor only. Repair as necessary. If vacuum source is okay, 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. Replace MAP sensor if values are not as specified. If MAP sensor is okay, check engine compression and ensure false air is not entering intake system. If no problems are found, replace PCM. Retest system.
