P2142 OBD-II: Exhaust Gas Recirculation Throttle Control Circuit "A" High
P2142 Severity
Will P2142 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 P2142?
While this code description suggests there is a fault within the EGR system, this code actually refers to an electrical issue with the intake throttle actuator. The Intake Throttle Actuator is what opens and closes the throttle plate on an electronic throttle body. When the engine control module (PCM) detects an issue with the intake throttle actuator, the PCM will set code P2142.
