P2592

Cruise Control Front Distance Range Sensor Right

Cruise control / driver assist Generic OBD-II Medium

What it means

P2592 is set when the module can't get a valid reading from the right-hand front distance (radar) sensor used by adaptive cruise control and forward-collision systems. The engine runs normally, but those driver-assist features shut down. It's usually a blocked, misaimed, or failed sensor, or a wiring problem at its connector.

Medium

Can I keep driving? Yes — the engine and brakes work normally, but adaptive cruise control and any forward-collision assist that relies on this radar are disabled, so don't count on them.

Inspect the front bumper for impact or misalignment that could throw off aim.
Check the sensor connector and wiring for damage, corrosion, or a loose pin.
Scan the driver-assist module and follow the sensor-aiming/calibration procedure.
Replace and recalibrate the radar sensor if it fails testing.

FAQ

Quick answers

Is it safe to drive with P2592?+

Yes for normal driving — the engine, steering, and brakes are unaffected. But adaptive cruise and forward-collision assist may be off, so drive as if you have none of those aids.

Can I just clear P2592?+

You can, but if the sensor is blocked, misaimed, or faulty the code returns and the assist features stay disabled until it's fixed and recalibrated.
