The P007F: Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation refers to a problem with the correlation between the temperature readings from the charge air cooler sensors on Bank 1 and Bank 2. This issue can result from a faulty temperature sensor, issues with the sensor correlation, wiring or connection problems, or a failure in the Powertrain Control Module (PCM). In simple terms, when this code appears, it indicates that the engine’s control system is detecting a mismatch or inconsistency between the temperature readings of the two sensors, which could affect engine performance.
P007F – Quick Overview
| Meaning | P007F: Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation |
| Is it serious? | Yes, this code can be serious as it can lead to incorrect air temperature monitoring, potentially affecting engine performance and efficiency. |
| Possible causes | – Faulty charge air cooler temperature sensor – Sensor correlation issues – Wiring or connection problems – Faulty PCM |
| How to diagnose? | – Test both charge air cooler temperature sensors for proper operation. – Inspect the wiring and connectors between the sensors and PCM. – Check sensor outputs using a scan tool. – Replace or repair any faulty components. |
P007F Meaning
The P007F: Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation code indicates that there is a problem with the temperature readings from the charge air coolers on Bank 1 and Bank 2 not aligning as expected. This could be due to one or both sensors being faulty, issues with the wiring or connections, or a problem with the PCM. If the sensors are not reading correctly, it can cause the engine to mismanage air temperature, leading to performance issues.
Step-by-step diagnostic guide
Follow the outline procedure to diagnose this DTC by eliminating possible causes one by one.
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check if there are any other related codes present. These might give additional clues about the problem. | OBD-II Scanner |
| Test Both Charge Air Cooler Temperature Sensors | Test both charge air cooler temperature sensors for proper operation, ensuring they provide accurate readings. | Multimeter, Manufacturer’s Specifications |
| Inspect Wiring and Connectors | Inspect the wiring and connectors between the sensors and PCM for any signs of damage, corrosion, or disconnection. | Flashlight, Multimeter |
| Check Sensor Outputs with a Scan Tool | Use a scan tool to check the outputs from both sensors and compare them to ensure they are within the manufacturer’s specified range. | Scan Tool, Manufacturer’s Specifications |
| Repair or Replace Faulty Components | If any components, wiring, or connections are found to be faulty, repair or replace them as necessary. Ensure all connections are secure and free from corrosion. | Wire Strippers, Electrical Tape, Replacement Wires/Connectors |
| Clear the Code and Test Drive | After repairs, clear the P007F code using the OBD-II scanner. Take the vehicle for a test drive to ensure the issue is resolved and the code does not return. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P007F code has not reappeared. If the code returns, further diagnosis may be required. | OBD-II Scanner |
