P0507

Idle control system RPM higher than expected.

The engine's downturns were above the computer's target.

What should be checked

The air flow and control of the accelerator determine whether the engine reaches the target revolutions.

In plain language: It may be getting more or less air in than the computer needs to keep the engine stable.

How to check it: Check data, connections and leaks before cleaning or adapting electronic components.
Before correcting it: Do not force or clean an electronic accelerator without proper procedure. The correction is decided only after locating and confirming the defect.
Related components: This path may involve the throttle body, idle control if fitted, ducts, hoses, gaskets, or connectors. None has been confirmed.
When to stop: Consult a professional if the test requires the accelerator to be turned on, an adjustment made or the engine to be turned on.

Auxiliary loads, mixing corrections and learned values can shift the slowdown from the target.

In plain language: Another vehicle load or a learned adjustment may be causing revolutions to stay high or low.

How to check it: Record active loads, other codes, mix corrections and exact conditions when they occur.
Before correcting it: Do not delete learning or disconnect the battery as a substitute for the diagnosis. The correction is decided only after locating and confirming the defect.
Related components: This path may involve accessory loads, the charging system, electronic throttle control, or learned values. None has been confirmed.
When to stop: Stop if the vehicle is accelerating alone, is shut off in traffic or cannot be kept stable.
