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.

How to diagnose & fix
Work through it in order

- 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.
