The OBD2 code P007E signals a problem with the “Charge Air Cooler Temperature Sensor Circuit Intermittent Bank 1.” This means the sensor that checks how cold the air is after it goes through the cooler on its way to the engine isn’t working right sometimes. This can make your car run unevenly, like having a rough idle or not enough power when you step on the gas.
P007E quick overview
Meaning | P007E: Charge Air Cooler Temperature Sensor Circuit Intermittent Bank 1 |
Is it serious? | Yes, because it can cause uneven running and power loss. |
Possible causes | – Damaged sensor or wiring – Water getting into connections – Bad ground or power supply – Outdated software for the sensor |
How to diagnose? | Check for water or rust in the sensor plug. Test wiring for breaks or damage. Make sure the sensor gets the right voltage and ground. Look for software updates that might fix the sensor’s readings. |
P007E Meaning
When you get a P007E code, it’s like your car is saying the thermometer for the air going to the engine isn’t reliable. It might show the air as too cold or too hot because of a bad wire or connection. This messes with how your car runs, especially at different speeds.
Fixing it usually means finding where the wire is hurt or making sure the sensor is hooked up right and getting what it needs to work properly.

How to fix P007E – learn from mechanics
I looked into P007E service cases at iatn.com website where in the private forums the mechanics seek advice from other mechanics. I looked up a bunch of cases to help you decide how to fix your issue and see what would a real mechanic do to solve it.
Case #1: Mitsubishi P007E
Vehicle information
2015 Mitsubishi Lancer Evolution GSR, 2.0L turbocharged engine
Issue + repair history
- MIL lamp illuminated with code P007E
- Engine experiencing intermittent rough idle and reduced power
- Replaced charge air cooler temperature sensor
- Inspected wiring harness for any visible damage
- Code persisted after sensor replacement
Other OBD2 Codes + Test Results
- P007E: Charge Air Cooler Temperature Sensor Circuit Intermittent Bank 1
- No additional fault codes detected
- Live data shows intermittent fluctuations in temperature readings from the sensor
Mechanic suggestions
- Check for any signs of water intrusion or corrosion in the sensor connector
- Perform a continuity test on the wiring harness, paying attention to areas prone to damage
- Verify proper voltage supply and ground connection to the sensor
- Consider checking for any software updates related to sensor calibration
Final fix
Discovered a damaged wire in the wiring harness leading to the charge air cooler temperature sensor. Repaired the wire, cleared codes, and verified proper sensor function. Issue resolved.
Case #2: Audi P007E
Vehicle information
2009 Audi A4 Quattro Premium Plus, 2.0L turbocharged engine
Issue + repair history
- MIL lamp illuminated with code P007E
- Engine experiencing occasional hesitation and loss of power
- Replaced charge air cooler temperature sensor
- Inspected wiring harness for any visible damage
- Code persisted after sensor replacement
Other OBD2 Codes + Test Results
- P007E: Charge Air Cooler Temperature Sensor Circuit Intermittent Bank 1
- No additional fault codes detected
- Live data shows intermittent fluctuations in temperature readings from the sensor
Mechanic suggestions
- Perform a detailed visual inspection of the wiring harness, focusing on areas where it may rub against other components
- Use a multimeter to check for continuity and voltage drop along the wiring harness
- Consider checking the ground connection for the sensor and the PCM for any issues
- Verify proper installation and connection of the new sensor
Final fix
Discovered a loose ground connection near the charge air cooler temperature sensor. Tightened the ground connection, cleared codes, and confirmed proper sensor function. Issue resolved.
Case #3: Volkswagen P007E
Vehicle information
2015 Volkswagen Golf GTI, 2.0L Turbocharged engine
Issue + repair history
- Check engine light on with code P007E
- Intermittent loss of power reported by the driver
- Inspected charge air cooler temperature sensor and associated wiring
- Found damaged wiring near the turbocharger
- Repaired damaged wiring and replaced charge air cooler temperature sensor
- Cleared codes, but issue persisted
Other OBD2 Codes + Test Results
- P007E: Charge Air Cooler Temperature Sensor Circuit Intermittent Bank 1
- No additional fault codes detected
- Live data shows erratic temperature readings from the sensor
Mechanic suggestions
- Conduct a thorough visual inspection of the entire wiring harness, particularly around the turbocharger
- Use a multimeter to test for continuity and voltage drop along the wiring harness
- Ensure proper installation and connection of the new sensor
- Check for any boost leaks or other issues that could affect sensor readings
Final fix
Discovered a damaged wire in the wiring harness near the turbocharger. Repaired the wire, reinstalled the sensor, and cleared codes. Issue resolved, and vehicle returned to normal operation.
How to diagnose P007E
I made you an overview of solving this DTC, based on all the advice that was suggested by certified mechanics to address this issue in previously mentioned service cases.
Diagnostic Step | Brief Explanation |
---|---|
Check sensor connector for water | Water can cause the sensor to send wrong signals. |
Test wiring harness | Broken wires can stop the sensor from working right. |
Verify voltage and ground | The sensor needs proper power to give accurate readings. |
Update sensor software | New software can make the sensor more reliable. |
Tighten loose ground connections | A bad ground can make the sensor act up. |
Inspect for damage near moving parts | Wires can get hurt where they touch parts that move or get hot. |
Use multimeter for continuity and voltage | This helps find where the wire or connection is bad. |
Check installation of the new sensor | Making sure the sensor is in right can fix the problem. |
