P2072 OBD-II: Throttle Actuator Control System - Ice Blockage
P2072 Severity
Will P2072 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P2072?
The engine computer (PCM) is capable of detecting ice build up on the throttle body during cold startup. Many times, a blocked or leaking PCV can cause ice/oil build up in the throttle body or intake manifold that will lead to extended crank times during cold starts. If ice buildup is detected, code P2072 will set.
