Our certified mechanics come to you · Get a fair and transparent estimate upfront
P0570 is a diagnostic trouble code (DTC) for "Cruise Control Accel Malfunction". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $154.99 . Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $50.0 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.

The P0570 code indicates that the PCM has identified a malfunction with your vehicle’s cruise control.
Your vehicle’s PCM works with the cruise control module in order to enable you to automatically control the speed of your vehicle. If the PCM finds that the speed cannot be automatically controlled, then it self-tests the cruise control system, and stores a P570 code.
Most of the time, when a P0570 code is stored, the reason is a failure in the cruise control switch. If the switch is open or shorted (usually due to spilled liquids), then the switch will fail. Other causes can be blown fuses, or corroded connectors. Keep in mind, though, that if a fuse blows, this is generally an indication of a more serious problem.
Usually, if the PCM stores a P0570 code, you will not be able to use your cruise control. Other symptoms include:
Sometimes, the Check Engine Light will not come on until the failure has been recorded three times.
Your mechanic will begin by using a OBD-II scanner and ohmmeter to diagnose your P0570 code. Then, he or she will: * Visually inspect the connectors and wiring
Re-test your vehicle’s system to ensure that everything is in proper working order
Do a test drive to determine if the codes are cleared
Sometimes, codes may appear intermittently, and the mechanic may assume that the problem has been corrected when it actually has not. These intermittent controls can be difficult to diagnose, and sometimes the problem actually has to get worse before an effective diagnosis can be made. Sometimes, too, mechanics may assume the worst and replace many components without first checking for blown fuses and identifying the problem that is causing the fuses to blow.
In the grand scheme of things, a P0570 code is not a big deal at all. Not having your cruise control is not going to affect your safety at all, unless you rely on it to keep you at the proper speed limit when driving on the highway (which you should not do in any case). All that losing your cruise control means is that you will have to monitor your speed yourself, the same way that you would do if you were driving a vehicle that was not equipped with cruise control. If the lack of cruise control bothers you, then of course you are going to want to see a mechanic in order to have the problem corrected. You can do this at your leisure, though, because faulty cruise control is not a safety issue.
If the cruise control switch is faulty, then your mechanic can replace it. After doing so, he or she will test the cruise control system to make sure that the problem does not continue. If it does, then the drive wheels can be raised, and with a helper in the vehicle, the mechanic will rev the engine to the point where it gets to a speed that is going to activate the cruise control. Then, the electrical connector is disconnected and the switch tested for voltage. Shorted or open circuits will be identified, and then can be repaired. You’ll be cruising again in no time.
Using your cruise control as a means of reminding you to slow down is a bad idea. Watch your speed, and never assume that your cruise control is working correctly.
