The P2183 is a fairly straight forward code pointing to a fault in the ECT #2 sensor. It's a fairly common fail item on these vehicles. Inspect the wire harness and connector to the sensor for any loose, broken or rubbed through wires. If the visual inspection checks ok, suspect a faulty sensor, and replacement should solve the problem. It's mounted just under the throttle body.

I am SO sorry! Wow! I totally misread that! The heat is getting to me today! Sorry!

 

The P2138 is also a fiarly straight forward code pointing to a fault in the Accelerator Pedal Position Sensor. This sensor is mounted to the top of the Accelerator Pedal. Again, inspect for any loose, broken rubbed through or melted wires. If the visual inspection checks ok, suspect a faulty sensor.

I'm getting conflicting information. One source says, on this model year, the APP Sensor is under the hood, mounted to the firewall, towards the passenger's side.
