What is the P0511 fault number? What is the definition of Idle Air Control Circuit Malfunction How can you fix P0511 fault code What are the causes and symptoms of the P0511 error code?
What is the P0511 fault code? What does it all mean?
Every vehicle manufacturer sets a minimum RPM so that the vehicle can idle. The idle air controller (IAC) circuit regulates idle when the throttle plate closes (idle). This allows air to enter and exit the engine. The powertrain control module, or PCM, monitors the idle speed continuously to make sure it is within acceptable limits. If the PCM detects a problem it attempts to restore normal RPM. If this fails it sets the P0511 Code.
The P0511 fault code can affect vehicles of all makes and models, including Acura, Acura, Jaguars, Chery, Mazdas, Toyota, Chrysler Jeep, Ford, and Toyota.
What is the P0511 Fault Code and Why Does It Happen?

- – Defective idle control (IAC), or auxiliary air controller (AAC), valve
- – Corroded, damaged, burned, shorted or disconnected wiring and/or connectors
- – Suction system vacuum leaks are severe
- – Extremely dirty sensor for MAF
- – The PCM is inoperable or requires a new software update (rarely).
What are the Symptoms of P0511 Fault Codes?
You may experience the following symptoms if your vehicle has the code P0511.
- – Illumination for the check engine light
- Issues with high or low idle speeds
- Engine stalling at idle
- Engine stalling after the accelerator pedal is released during driving
- – Unusual sound from the throttle body
- – Other fault codes for the IAC system
How do I fix the P0511 fault code?
The following repairs may be able to resolve the P0511 fault code:
- – Clean the throttle body
- – Replacing throttle body
- Repair damaged wiring or loose connectors.
- Repair of engine vacuum leaks
- – Replacing an idle air control (IAC), valve
- – Reprogramming or replacement of a faulty PCM
How serious is the P0511 Fault code?
This code may prevent you from driving your vehicle if it is set. Drivers can be put in dangerous situations if the vehicle suddenly stops. The fault should be immediately diagnosed and fixed.
