P0106 code popped up

Good morning,

This code could be the MAP sensor but needs to be confirmed. You need to verify voltage to the sensor and the sensor operation. Make sure the vacuum line is attached and has vacuum at idle.

I attached a picture of the part from rock auto.

I also attached a flow chart for you to follow. If you have a scan tool, that would make it easier.

DM15 DTC P0106: MAP RANGE/PERFORMANCE

Note:If MAP DTC(s) P0107, P0108 or P0109 are present, diagnose those DTC(s) first. If any mass air flow (MAF) sensor related DTCs are present, diagnose those DTCs prior to diagnosing MAP DTC P0106. Disregard any DTC(s) generated as a result of this test.
