P2587 Cruise Control Front Distance Range Sensor Intermittent/Erratic
P2587 is a generic OBD2 powertrain code. It means “Cruise Control Front Distance Range Sensor Intermittent/Erratic” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.

What the wording tells you
“Intermittent” or “erratic” means the signal dropped out or jumped for brief moments. Look for a loose pin, a chafed wire that shorts over bumps, or corrosion — and expect the fault to hide at the workshop; wiggling the harness with the engine running often brings it out.
Can I keep driving with P2587?
The rule of thumb for this area (speed, idle control & auxiliary inputs): It depends a lot on the code. Cruise-control and A/C codes can wait; speed-sensor codes affect shifting and the speedometer; charging-system and oil-pressure codes can leave you stranded or damage the engine — check those straight away.
How P2587 breaks down
Powertrain. Engine, transmission, fuel and emissions — the codes behind the check engine lamp.
Generic code: defined by SAE, the same on every make.
Speed, idle control & auxiliary inputs.
The specific fault within this range.
Where to look: Speed, idle control & auxiliary inputs
Vehicle speed sensors, idle speed control, cruise control, A/C pressure sensors, the charging system and battery voltage, oil pressure and level, and the brake and clutch switches — the signals the engine computer takes from outside the engine itself.
Typical causes in this area
- Speed sensors, switches and their wiring
- A dirty throttle body or idle air control valve
- The battery, the alternator and ground connections
- Vacuum leaks that upset the idle

What does P2587 mean?

What causes P2587?
“Intermittent” or “erratic” means the signal dropped out or jumped for brief moments. Look for a loose pin, a chafed wire that shorts over bumps, or corrosion — and expect the fault to hide at the workshop; wiggling the harness with the engine running often brings it out. Typical causes in this area: Speed sensors, switches and their wiring; A dirty throttle body or idle air control valve; The battery, the alternator and ground connections; Vacuum leaks that upset the idle.
How do I clear P2587?
Fix the cause first, then clear it with any OBD2 scanner or app. Once the fault is gone the car also clears it on its own: the check engine lamp goes off after the self-test passes on three drive cycles in a row, and the stored code ages out after about 40 warm-ups. Clearing without a repair only hides it for a while — and resets the readiness monitors an emissions inspection looks at.
Is P2587 the same on every car?
Yes. P2587 is a generic SAE J2012 code, so its definition is identical on every make and model. What differs is the cause behind it and the repair procedure, which depend on the engine — that’s why the assistant on this page asks for your car.
