IAC Idle Air Control Valve 17100016 00016 C2177 AC5
How to Diagnose and Fix a Bad Idle Air Control Valve?
Accessing the IAC valve can be tricky. So, rather than doing DIY repairs, have a mechanic diagnose and fix the issue to save time.
Here’s how they would tackle a bad IAC valve:
A. Diagnose a Bad Idle Air Control Valve
After checking the idle speed, there are two primary ways a mechanic will diagnose a bad idle control valve:
- Identify the diagnostic code: Connect the OBD2 scanner to the vehicle’s computer system and read the error code. A P0505 error code indicates a bad idle control valve.
- Measure the electrical current: Attach the multimeter to each valve terminal and note the reading. Any fluctuations or readings outside 0.00-0.05 indicate a bad idle control valve.
If the valve is bad, the mechanic will clean or replace it.
B. Clean the Idle Air Control Valve
To clean idle air control valves, they’ll:
- Locate the IAC valve and remove the intake hose from the throttle body.
- Detach the vehicle’s battery cable from the negative terminal.
- Loosen the screws connecting the idle control valve with the throttle body.
- Disconnect the electrical plug and wires.
- Remove the hoses and clamps connected to the IAC valve.
- Take off the gasket around the valve.
- Use a carb cleaner to remove debris from the idle control valve and intake manifold.
- Clean the throttle body by using a throttle body cleaner.
- Replace the gasket.
- Reconnect the IAC valve to the throttle body, followed by the electric plug and hoses.
- Reconnect the battery.
- Turn on the vehicle and leave it running to determine if there’s still an idle issue. The idle control valve is likely working if the engine idle is consistent.
However, if there’s a fluctuating idle speed, it means the idle control valve still isn’t working. So they’ll replace it.
C. Replace the Idle Air Control Valve
Here’s how to replace the idle air control valve:
- Locate the idle air control valve and use a wrench to detach any parts in the way. It’s typically found within the throttle body.
- Unplug the electrical connector.
- Remove the gasket and old idle air control valve.
- Attach the new idle control valve to the throttle body.
- Attach the electrical connector and any other previously removed components.
