The idle air control (IAC) sensor on a 2000 Saturn L-Series is located on the throttle body. To access it, you typically need to remove the air intake duct and possibly other components to reach the throttle body. The IAC is usually mounted on the side of the throttle body and can be identified by its electrical connector and small cylindrical shape. Always consult a repair manual for specific instructions and safety precautions.
Could be throttle plate stuck open Try to free it with screwdriver with engine off
Two of the most common causes are throttle position sensor and idle control valve problems.
your airflow is uneven check the airflow sensor wire/ sensor
I had those symptoms and finally had the dealer look at it. the problem was with my cooling system and temp sensor. the car was running hotter than the temp sensor was indicating and the cooling system was not working properly.
Replace engine mounted temperature sensor and IAC valve(or clean throttle body and IAC according to an automotive manual). Before trying both of these, replace PCV valve to correct any vacuum problems.
no, the MAF sensor is between the air filter and throttle body. the idle controll is at the throttle body.
The 2000 Saturn SL1 may idle high due to several factors, including a malfunctioning idle air control (IAC) valve, vacuum leaks, or issues with the throttle position sensor (TPS). A dirty or faulty IAC can lead to improper airflow, causing the engine to maintain a higher idle speed. Additionally, vacuum leaks can introduce excess air into the intake system, affecting engine management. Regular maintenance and diagnostics can help identify and resolve the underlying issues.
My 2000 V6 Sonata shakes while at idle also. I discovered I need an oxegen sensor and more importantly an "Idle Air Control Valve". 239.00 is the average and hard to find. .
Sounds like the Throttle Position Sensor.
Yes. IT can make the engine run to rich, and then cause misfires
Replace the engine coolant temperature sensor. Your car has two, replace the one with the 2 wire connector
Idle air control valve sensor is located around the carburetor .
