This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in the car that checks the temperature of the air going into the engine is showing a temperature that's too high. It's like a thermometer saying it's way hotter than it should be.
The P12CE code is triggered when the Engine Control Module (ECM) detects a temperature reading from the Charge Air Cooler Temperature Sensor that is higher than the expected range.
The Charge Air Cooler Temperature Sensor measures the temperature of the air after it has been cooled by the charge air cooler (intercooler). This sensor ensures that the air entering the engine is at the correct temperature for optimal performance. If the sensor reads a temperature that is too high, it could indicate a problem with the sensor itself, the wiring, or the cooling system.
• Check Engine Light is on
• Poor engine performance
• Reduced fuel efficiency
• Faulty Charge Air Cooler Temperature Sensor
• Wiring issues such as shorts or open circuits
• Malfunctioning charge air cooler
ECM: Engine Control Module
Intercooler: A device used to cool air compressed by a turbocharger or supercharger before it enters the engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the sensor.
• Test the Charge Air Cooler Temperature Sensor for proper operation.
• Replace the Charge Air Cooler Temperature Sensor if faulty.
• Repair or replace any damaged wiring or connectors.
• Check and repair the charge air cooler if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and maintain the charge air cooler.
• Check sensor connections periodically.
• Keep the engine cooling system in good condition.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regular maintenance can prevent such issues.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been reported in vehicles with turbocharged engines where the charge air cooler is a critical component.
Moderate – While the vehicle may still be drivable, it is recommended to address this issue to prevent further engine performance problems.
Driving with a malfunctioning sensor can lead to increased emissions and potential engine damage. Always address check engine light issues promptly.
• Engine at operating temperature
• Vehicle at idle or under load
The Charge Air Cooler Temperature Sensor is typically located near the intercooler or along the intake air path.
Q: Can I drive my car with a P12CE code?
A: While the car may still be drivable, it's best to fix the issue to avoid potential engine damage.
Q: How can I reset the Check Engine Light?
A: After repairs, you can use an OBD-II scanner to reset the light, or it may turn off after several drive cycles if the issue is resolved.
