P007C
Charge Air Cooler Temperature Sensor Circuit Low Bank 1
Forced induction / charge air temperature
Generic OBD-II
Low
What it means
P007C means the bank 1 charge air cooler (intercooler) temperature sensor circuit is reading a lower voltage than expected, typically from a short to ground or a failed sensor. This sensor tells the ECM how hot the compressed intake air is after the intercooler; a bad reading can slightly affect boost and fuel tuning, but the engine keeps running and the fault is electrical rather than mechanical.
Low
Can I keep driving? Safe to drive — the engine runs; the ECM loses an accurate charge-air temperature reading, which can slightly affect boost/fuel tuning but won't strand you.
Common symptoms
What you'll notice
- Check-engine light on
- Often no noticeable change in driving
- Occasional slight drop in throttle response under boost
- Charge-air temperature reads implausibly low in scan data
Common causes
Most likely first
- Short to ground in the charge air cooler (intercooler) temperature sensor wiringLikely
- Failed charge air cooler temperature sensor reading out of range lowCommon
- Corroded or damaged connector at the sensorCommon
- Chafed harness contacting ground near the intercooler plumbingLess often
- Faulty engine control module (ECM), rarelyLess often
How to diagnose & fix
Work through it in order
- Locate the bank 1 charge air cooler (intercooler) temperature sensor in the intake/charge-air plumbing.
- Inspect its connector and wiring for a short to ground, chafing, or corrosion.
- Compare the sensor's live reading to the actual intake air temperature; a stuck-low value confirms the fault.
- Repair the wiring or replace the sensor if it reads out of range.
- Clear the code and confirm the charge-air temperature reads plausibly.
FAQ
Quick answers
Is it safe to drive with P007C?+
Yes. It's a charge-air temperature sensor circuit fault, not an engine-stopping problem. The ECM may adjust tuning slightly, but the car drives normally. Fix it to clear the light.
Can I just clear P007C?+
It returns if the wiring short or failed sensor remains, since the ECM keeps monitoring the circuit.
