P1599 and p2138?

P1599 - means that the computer detected that the engine stalled when the ignition had not been turned off.
Does your vehicle have a stalling problem?

P2138 - is the Accelerator Pedal Position Sensor 1-2 correlation.
The accelerator pedal has a sensor and the throttle actuator has the one as well. the computer expect thats both sensor will read the same as the accelerator pedal is operated. If one sensor read differently from the other the computer will set this code.

Long story short, you'll have to have shop to check this code out for you since a scan tool will be needed in the diagnosis of this code.

What does check engine light P2138 code mean and how to fix it?

P2138 Throttle/Pedal Pos Sensor Voltage Correlation

Potential Causes of P2138 DTC It's been my experience that the wiring connector or "pig tail" on the throttle body gives problems in the form of a poor connection.The female terminals on the pigtail corrode or pull out of the connector. Possible bare wire on pigtail shorting to ground. The top cover on the throttle body distorted preventing the gears from turning properly. The electronic throttle body is faulty. The accelerator pedal sensor or its wiring failed. The engine management computer has failed. The TPS sensors were not correlating for a few seconds and the computer needs to be cycled through its relearn phase to restore active response to the throttle body, or the computer needs reprogramming at the dealer.
