What does the idle control system code mean?
The role of the Idle Control System is to manage the engine’s idle speed and meet the fluctuating load placed on the vehicle’s engine, which varies from the use of air-conditioning, heater, wiper, etc. Error Code P0507 means the idle speed is faster than normal. This code is sometimes triggered on vehicles with electronic throttle control.
When is the p0507 idle air control system higher than expected?
In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM.
How to check Idle Speed Control ( IAC ) function?
When testing IAC function with the steering wheel, be sure to check that the PSP VSV is functional. You can check this by plugging or pinching the inlet VSV inlet hose or filter and seeing if the idle speed changes. With the power steering system inactive, no idle-up should be expected.
Where is the idle air control motor located?
The idle speed is usually controlled by the Idle Air Control Motor, which is mounted on or the back side of Throttle Body’s Intake Manifold. Vehicles made since 2000 use ‘drive by wire system’, where the Idle Air System is incorporated straight to Electronic Throttle Body’s assembly.
What does DTC stand for in idle air control?
Idle Air Control (IAC) System RPM Lower Than Expected This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
What is the diagnostic code for idle control system rpm higher?
P0507 is a diagnostic trouble code (DTC) for “Idle Control System RPM Higher Than Expected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
