P2592 code meaning
Cruise Control Front Distance Range Sensor Right
What P2592 means
P2592 marks a fault of the right-hand front distance sensor in multi-radar adaptive cruise layouts; the left unit reports P2591, a single or centre radar P2583. No maker publishes this code. Compared with a radar behind the grille emblem, a right corner sensor is more exposed to kerb and parking contact, stone chips and road salt reaching its connector, and it is often disturbed when a bumper is replaced on the passenger side. That is why aiming and mounting are checked before parts are swapped. Honda's P2583 bulletins illustrate the usual chain: dirt or ice on the radar face leads to a misalignment report and a temporary shutdown of the assistance. The engine module only keeps the record; the detailed cause is stored in the driver assistance or radar module. Driving itself is unaffected.

Symptoms of P2592
- Adaptive cruise control switched off
- Warning message for the radar or driver assistance system
Common causes of P2592
- Most likelyRight sensor knocked out of alignment by kerb or parking contact
- PossibleRoad salt or water corrosion at the right sensor connector
- PossibleSensor not recalibrated after bumper replacement
- Less likelyRight radar sensor internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note P2592 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2592
What does P2592 mean?
P2592 means "Cruise Control Front Distance Range Sensor Right". P2592 marks a fault of the right-hand front distance sensor in multi-radar adaptive cruise layouts; the left unit reports P2591, a single or centre radar P2583. It is a generic code, so it means the same on every make.
Is it safe to drive with P2592?
P2592 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2592 fail an emissions test?
P2592 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2592 to fix?
Difficulty: hard. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2592 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
