All three of those codes are for different items. How much diagnosis/repair are you going to do yourself?
Do you have a scan tool?
Are you certain that they are active codes and not history codes? Ie, have you reset them once already and they came back after normal driving?
OK. The p0106 is a MAP sensor code. The sensor is either faulty or has a bad connection.
Here is the test procedure from GM for this code:
⇒XIf decrease in pressure is not consistent, then test for intermittent and poor connections at the MAP sensor. If connections test OK, replace the MAP sensor.
J-23738-A is just a vacuum pump like this one:
P0113 is a MAF sensor code. This and the p0106 could be triggering one another. Here is how it is tested:
1. Check the Tan/Black wire for an open from the Mass Air Flow (MAF) to pin 42 of the Black Powertrain Control Module (PCM) connector. This is the ground wire for the intake air temperature sensor in the MAF.2. Check the solid Tan wire for an open or short to ground from the MAF to pin 62 of the Black PCM connector, this is the 5 volt from the PCM.3. If the 5 volt and ground are OK, jump the wire together and the scanner should read a high temperature, if OK, replace the MAF.
I would probably focus my efforts on checking for a broken wire at the connector before doing too much testing.
The p0449 is usually a bad evap canister vent solenoid/valve. The best thing to do with it is just replace it.
Please let me know if you need additional info.
I don't list the vent valve part # ***** the Malibu Maxx. I think it's 12592015 but you might verify with the dealer.
