P007B
Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 1
Turbo / boost control
Generic OBD-II
Low
What it means
P007B means the charge air cooler (intercooler outlet) temperature sensor on bank 1 is giving a reading that doesn't make sense for the current conditions. It's usually a wiring, connector, or sensor drift issue rather than an engine problem, so the car keeps running normally while the code is set.
Low
Can I keep driving? Safe to keep driving — the engine usually runs normally, with at most slightly reduced performance or economy until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Charge-air (intercooler outlet) temperature reads implausibly for conditions
- Slightly reduced performance or fuel economy in some vehicles
- Often no noticeable driving symptom beyond the light
Common causes
Most likely first
- Loose or corroded connector at the charge air cooler temperature sensorLikely
- Damaged or chafed sensor wiringCommon
- Contaminated or drifting charge air cooler temperature sensorCommon
- Boost/intake leak skewing the temperature the sensor seesLess often
- Faulty engine control module (ECM) — rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and view the live charge-air temperature reading.
- At a cold key-on, compare it to intake-air and ambient temperature — they should read close.
- Inspect the sensor connector and wiring for damage or corrosion.
- Check the intercooler and boost plumbing for leaks that could distort the reading.
- Replace the sensor if it reads out of range; consider the ECM last. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P007B?+
Yes. This is a low-severity monitoring code; the engine runs normally, though it's worth fixing so boost-related adjustments stay accurate.
Can I just clear P007B?+
You can, but it will return until the sensor, wiring, or connection giving the implausible reading is repaired.
