P007F
Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation
Turbo / charge-air cooling
Generic OBD-II
Low
What it means
P007F sets when the bank 1 and bank 2 charge-air-cooler (intercooler) temperature sensors disagree by more than the ECM expects. These sensors measure post-intercooler intake temperature on each bank; a mismatch usually means one sensor is drifting or has a wiring fault, though a real cooling difference between banks can also trigger it. The engine runs normally and it won't cause a no-start.
Low
Can I keep driving? Generally safe to drive; the engine runs normally with at most a slight performance change.
Common symptoms
What you'll notice
- Check-engine light on
- Often no noticeable driving symptoms beyond the warning light
- Possible slight loss of power
Common causes
Most likely first
- One charge-air-cooler temperature sensor drifting or reading inaccuratelyLikely
- Wiring or connector fault on the bank 1 or bank 2 sensor circuitCommon
- A genuine temperature difference between banks (uneven intercooler airflow)Common
- Corroded or loose sensor connectorLess often
- Failed ECM/PCM input (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and compare the bank 1 and bank 2 charge-air temperatures — they should track closely.
- Identify which sensor is out of line and inspect its connector and wiring.
- Check both sensors' resistance against spec and replace the drifting one.
- Verify there's no real airflow/cooling difference (blocked intercooler core) causing the split.
- Repair the fault, clear the code, and road-test.
FAQ
Quick answers
Is it safe to drive with P007F?+
Usually yes. The mismatch mainly affects fine boost/fuel tuning. Fix it to keep performance and economy normal.
Can I just clear P007F?+
It will return once the two sensors again disagree. Repair the faulty sensor or wiring first.
