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.
