RAM P007B Code is a diagnostic trouble code (DTC) related to the intake manifold temperature sensor circuit on the RAM Cab and Chassis and the Regular Cab. This code indicates that the Powertrain Control Module (PCM) is not able to accurately monitor the change in voltage caused by changes in the temperature of the Charge Air Cooler. This can lead to white smoke, the fan running more often, and the Malfunction Indicator Lamp (MIL) being illuminated. Fortunately, there are many possible causes and solutions for this DTC.
Causes and Solutions for RAM P007B Code
| Cause | Solution |
|---|---|
| Air Cleaner Box not Sealing Properly to the Inlet Air Tube | Check the air cleaner box for any damage and ensure it is securely fastened to the inlet air tube. |
| Dirt or Debris in Charge Air Cooling System | Clean the charge air cooling system of any dirt or debris. |
| Temperature/Pressure Map Sensor | Replace the temperature/pressure map sensor if it is faulty. |
| Damaged Wiring | Check the wiring for any damage and replace as necessary. |
Air Cleaner Box
The air cleaner box needs to be checked to ensure that it is properly sealing to the inlet air tube. If it is not, then air can escape and the air-to-fuel ratio will be off, causing the RAM P007B Code to appear. To fix this, the air cleaner box should be checked for any damage and securely fastened to the inlet air tube.
Dirt or Debris
When dirt or debris gets into the charge air cooling system, it can cause the RAM P007B Code to appear. This is because the debris can block the air flow and cause the air-to-fuel ratio to be off. To fix this, the charge air cooling system should be cleaned of any dirt or debris.
Temperature/Pressure Map Sensor
The temperature/pressure map sensor is responsible for monitoring the change in voltage caused by changes in the temperature of the Charge Air Cooler. If the sensor is faulty, then the RAM P007B Code will appear. To fix this, the temperature/pressure map sensor should be replaced.
Damaged Wiring
The wiring of the intake manifold temperature sensor circuit can become damaged over time, leading to the RAM P007B Code being displayed. To fix this, the wiring should be checked for any damage and replaced as necessary.
Conclusion
The RAM P007B Code is a diagnostic trouble code (DTC) related to the intake manifold temperature sensor circuit on the RAM Cab and Chassis and the Regular Cab. It is important to identify the exact cause of this code and take the necessary steps to fix it. Common causes of this code include air cleaner box not sealing properly to the inlet air tube, dirt or debris in the charge air cooling system, a faulty temperature/pressure map sensor, and damaged wiring. By taking the time to identify and address the cause of the RAM P007B Code, you will be able to ensure the optimal performance of your vehicle.
