If the codes are the same for your model as mine:

13 is the intake air sensor - located in the air filter housing as the MAF sensor unit. It's a multi-role sensor that is difficult to test accurately for all functions. There is a resistance test for at least one function, but I'd suggest substituting one from a running truck and see if anything changes.... those sensors are expensive if bought new.

25 is the barometric pressure sensor - also a part of the air flow meter sensor group.

My guess is a bad MAF sensor - try one before buying it. If you want to run the simple test, pull the connector and test with an ohmmeter between terminal 4 & 6.... resistance should be ~2.7K ohms (2700 ohms) at 68F degrees. If it passes that test, heat the sensor with a hair dryer and the resistance reading should decline as temperature increases.

If the sensor seems ok and replacing it with another doesn't help, you might need an ECU.... hope not.

[EDIT] Before you go to too much effort, make sure the sensor plug isn't loose or disconnected... check the terminals for corrosion.... plug and unplug it a few times to get a good clean connection and try it.... if that does no good, try the above.[EDIT]
