P011B OBD-II: Engine Coolant Temperature/Intake Air Temperature Correlation
P011B Severity
Will P011B 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 P011B?
The Engine Coolant Temperature Sensor measures the temperature of the coolant going through the engine. The Intake Air Temperature Sensor measures the temperature of the air going into the engine. The engine control module (PCM) will compare the two readings to determine if sensors are reading correctly. When the PCM determines that one of the sensors has an irrational reading, it will set code P011B.
