P0570 — Problem with cruise control acceleration signal

The code indicates an issue with the cruise control system's accelerate signal. It appears when the vehicle's computer detects a fault in the wiring, switch, or related components that control accelerating while cruise control is active.

Common causes

The cause is almost always one of a few things. Here they are — P0570 rarely comes from anything outside this list:

• Faulty cruise control switch or button
• Damaged wiring or connectors in cruise control circuit
• Blown fuse related to cruise control
• Malfunctioning cruise control module or PCM

Where to start

In the order a sensible mechanic would work — the cheap checks first, the expensive replacements only after:

1. Check and replace blown fuses
2. Inspect and repair wiring and connectors
3. Test and replace cruise control switch if faulty
4. Diagnose and replace cruise control module or PCM if needed

That is what holds for P0570 in general. From here it depends on your engine — tell me which car it is and what it does, and I will give you the steps for it: real procedures, torque figures and diagrams instead of general advice.
