Hi,

Code P2104 is an informational code indicating a forced idle. When this code shows up, the manual indicates to diagnose other codes before focusing on it. See pic 1 below.

Coder P2112 indicates the throttle plate is at an angle further than commanded by the PCM. This leads me to a list of diagnostics specific to the P2112 which I have attached below.

The diagnostics include 30 tests, so they are somewhat extensive. However, you may find the issue within the first few tests.

Let me know if this helps or if you have other questions.

Take care,

Joe
