P024F
Charge Air Cooler Bypass Position Sensor A Circuit High
Turbo / boost control
Generic OBD-II
Low
What it means
P024F means the "A" charge air cooler (intercooler) bypass position sensor is reporting an abnormally high signal voltage. That sensor tells the module where the intercooler bypass valve is positioned, so a high reading usually points to a short to voltage, an open ground, or a failing sensor. It's an electrical fault affecting boost-air management, not something that stops the engine from running.

Can I keep driving? Generally safe to drive — this is a position-feedback sensor for the intercooler bypass, so you may see minor performance effects but no immediate risk.
Common symptoms
What you'll notice
- Check-engine light on
- Often no noticeable driving symptoms
- Possible slightly reduced performance under boost
- Higher intake air temperatures in some conditions
Common causes
Most likely first
- Signal wire shorted to voltage or open (reads high)Likely
- Faulty charge air cooler bypass position sensor 'A'Common
- Corroded or loose sensor connectorCommon
- Damaged sensor ground circuitLess often
- Faulty control module (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and locate the charge air cooler bypass position sensor 'A'.
- Inspect the connector and wiring for a short to power or an open ground.
- Check the sensor's reference voltage, signal, and ground against spec.
- Replace the position sensor if it reports out of range with good wiring.
- Repair damaged wiring or connectors if the sensor tests good. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P024F?+
Usually yes. The bypass position sensor mainly affects intake-air temperature management, so short-term driving is low-risk, but get it checked to keep boost performance right.
Can I just clear P024F?+
It comes back once the ECM reads the high signal again. The wiring or sensor has to be repaired first.
