P0127 OBD-II: Intake Air Temperature Too High
P0127 Severity
Will P0127 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 P0127?
The Intake Air Temperature Sensor measures the air temperature going into the engine. The engine control module (PCM) uses this information to determine how much fuel to use to keep the engine running properly. When the PCM detects a problem with this sensor or the circuit for the sensor, it will set code P0127.
