P0511 - OBD Trouble Code

<<See All OBD Codes

Love hitting the roads but hate the halts? Not anymore! With Parts Avatar get ready to experience smooth and unstoppable journeys. Here’s how you can crack the error code P0511. The idle control system controls the speed of the engine idle. In order to increase or decrease the engine idle speed, the engine control module (PCM) opens and closes the idle air control valve to allow the desired air into the engine. When the PCM fails to achieve the required RPM, it sets the code P0511. The DTC P0511 denotes idle air control circuit, signalling an abnormal condition in the RPMs while the engine is idling. Still not getting it? Well, we have such in store for you.

This system automatically monitors engine idle speed to an instructed level. The idle speed is managed through fine adjustments of the quantity of air that by-passes the throttle valve via idle air control valve (IACV) and the auxiliary air control (AAC) valve. The IACV-AAC valve keeps changing the opening of the air bypass passage in order to monitor the amount of auxiliary air. This valve is operated by a step motor built into the valve that moves the valve in the axial direction in steps corresponding to the ECM output signals.

What causes this problem with Idle Air Control Circuit?

• An unsound Idle Air Control (IAC) valve or auxiliary air control (AAC) valve.
• A defective PCM (that’s likely rare to happen).
• Extreme vacuum leaks.
• Short or open in the Electrical circuit like a damaged IAC valve harness.

1. Powertrain Control Module - The cause behind recurrent occurrence of the OBD error code P0511 could also be due to a fault in the PCM. Visit Parts Avatar to purchase top notch PCMs. So, order now!
2. IAC Valve Harness - Shortened or corroded harness? Get your error code fixed instantly with a new IAC Valve Harness. Parts Avatar is just the right place that provides the best harnesses across the country.
3. Connectors (connections) - Distorted or corroded Connectors can end up being the chief host inviting the error code P0511. So, replacing one can be one of the wisest decisions to avoid a problematic system.

Here are a few steps that can make the detection and diagnosis easy. Follow the steps to combat the error code P0511.

• Connect the vehicle to the scanner to record the data and identify any existing error codes.
• The DTC’s should be cleared out from the vehicle’s computer. Then the vehicle should be tested on road to see if they return (to identify an intermittent condition).
• The IAC wirings and connectors should be visually inspected for any damages or loose connections.
• Next, use a scanner to manually open the IAC motor, and then the IAC motor connector voltage should be tested.
• An inspection should be performed of the throttle body for coking and carbon build-up (the coke appears as a greasy black substance).

Common Mistakes When Diagnosing the P0511 Code

Stressing over a misdiagnose? Don't worry! We have listed here a few common mistakes that should take care of while performing a diagnosis.

Many a times, the idle air control parts are restored without making sure of the throttle body being unrestricted. In order to repair the problem accurately, the cleansing of the throttle body can be a chosen as option but often than not the required chemicals damage the wirings and connectors in the immediate vicinity. Replacements are usually the better options.
