P2583 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Facing troubles with your vehicle’s cruise control system? Wondering what might be the issue behind it? Well, if you have service engine light illuminated then chances are that your vehicle is set to OBD error code P2583. How harmful it can be for yourself? To find this out have a look at the sections below.

Your vehicle’s front distance range sensor is responsible for detecting the light that is reflected by the vehicle ahead. It calculates on the basis of the detected signal the distance from the ahead vehicles and the relative speed and transfers this information to the cruise control unit. The cruise control unit requests the engine control module to set the OBD P2583 error code when there exists any sort of miscommunication or the loss of communication with the front distance range sensor. In other words, error code P2583 will be set by your vehicle’s engine control module when the sensor is covered in debris or when it sends back an implausible signal. To know more about this error code and few of its common causes, take a look at the sections below.

What causes this problem with the Cruise Control Front Distance Range Sensor Single Sensor or Centre?

• Front distance range sensor that is faulty
• Open or shorted front distance range sensor harness
• Poor electrical connections of the front distance range sensor

1. Distance Range Sensor - A faulty distance range sensor can result in illumination of the check engine light and flashing of OBD error code P2583. So, if you face this issue then we recommend you to get rid of the problem by replacing the faulty distance range sensor with a brand new one.
2. ECM - Error code P2583 flashing? It might be due to a faulty ECM. Engine control module if faulty can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
3. Cruise Control Unit - It is responsible for automatically controlling the vehicle speed, so it makes it mandatory to keep it in good shape. If you have a bad one installed in your vehicle, we recommend you to get a new one for your vehicle today with us.
4. PCM - As your car’s PCM is responsible for making the engine and transmission work in synchronisation. Any issue with the powertrain control module will cause major problems with the efficient running of the vehicle. So, don’t think twice and replace the faulty PCM now to get rid of this error code P2583.
5. Cruise Control Module - For those who don’t know this already, we would like to inform you that takes charge of the throttle of your vehicle to maintain a steady speed as set by you. So, if you face any troubles with it, then replace that at the earliest.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2583 here:

Common Symptoms

• Illumination of service engine soon lamp

Here are some ways with the help of which you will be able to correct the OBD Code P2583

• Repair or replace the faulty front distance speed sensor
• Undergo replacement for the open or shorted front distance speed sensor harness
• Make sure that all the electrical connections are in good shape
• If PCM is discovered to be faulty, undergo it’s replacement too

Here are some steps which you should follow in order to diagnose this fault code:

In order to diagnose OBD error code P2583, you will need to look for the technical service bulletins, also known as the TSB’s specific to your vehicle make model and year. Believe us this will save you a lot of time and will guide you in the right direction.

Your vehicle’s speed sensor data is utilized by the powertrain control module to help regulate vehicle speed when the cruise control is activated. There are many vehicles in which a small servo motor is attached to the throttle linkage. Voltage received from the PCM and the cruise control module prompt the servo motor to open or close the throttle plate as per the requirement.

There is a steel cable inside of a plastic housing is often utilized between the cruise control servo and the throttle linkage. If the desired speed is less than the actual speed, then the throttle plate will be opened and if the actual speed is more than the desired speed, the throttle plate should be allowed to close. If there is an opened throttle plate, then it would cause engine RPM and vehicle speed to increase in order for the automobile to reach the desired speed.

In case the throttle plate is closed, engine RPMs would decrease as well as the vehicle speed. There are other automobiles which are equipped with a drive by wire throttle system that utilizes no accelerator cable. These types of automobiles control vehicle speed with the same actuator motor which opens and closes the throttle plate during normal driving. There are several tools which would be instrumental in diagnosing this error code successfully. An OBD-II scanner and a digital volt/ohmmeter would prove to be helpful in performing a successful diagnosis. The automobiles that are equipped with adaptive cruise control systems utilize infrared sensors and lasers to detect vehicles and other objects that could potentially impede travel. The activity in the vehicle's lane of travel is monitored by the adaptive cruise control systems and then the speed of the vehicle is adjusted accordingly. Then the next step would be to perform a visual inspection of all wiring as well as connectors.

You will have to repair or restore the defective, disconnected, shorted, or corroded wiring, connectors, and components as per the requirement. Also, make sure to retest the system after repairs are completed to ensure success. If all system wiring, connectors, and components appear to be in good working condition, then you should connect the scanner to the diagnostic connector and then record all stored codes as well as freeze frame data. This information can be extremely helpful in diagnosing intermittent conditions that may have contributed to this code being stored. Then you should continue by clearing the code and operating a vehicle to see if it returns. This will help to decide whether or not the malfunction is intermittent.

Now once the codes have been cleared, then the vehicle should be taken out for a test drive to see if the code returns. If the code fails to immediately return, then you might have an intermittent condition. Intermittent conditions can prove to be quite challenging to diagnose and in extreme cases it should be allowed to worsen before a right diagnosis can be made. If the system parts seem to be in proper working order, then it would mean that there is faulty cruise control switch. Then the switch should be carefully replaced, then drive the vehicle and operate the cruise control system at length to ensure that the problem does not persist. If the code returns, or the cruise control fails to set at the desired speed, raise the drive wheels and safely secure the vehicle. Utilize a helper inside the vehicle, place the vehicle in drive and allow the speedometer to reach a speed sufficient to set the cruise control (usually 25 to 35 mph). The electrical connector from the cruise control switch should be disconnected and test for voltage using the digital volt/ohmmeter. After that you should compare your findings with manufacturer's specifications and restore the switch if readings coincide. If there is no voltage or ground signal at the switch, then the PCM should be disconnected and cruise control module connectors and perform a continuity test on the circuitry between the switches in the passenger compartment, the relevant fuse panel, and the powertrain control module.

Next step would be to compare your findings to manufacturer's specs and the open or shorted circuits should be repaired as per the requirement. The codes which are present should be cleared up and the entire system should be retested. If there are no malfunctions in the continuity test, then you should perform a resistance test on the cruise control on/off switch and buttons by using the digital volt/ohmmeter. Make sure to leave the cruise control module and PCM disconnected before testing circuit resistance. The cruise control switches should be replaced as per the need. All the codes should be cleared up and then retest the system.

Common Mistakes When Diagnosing the P2583 Code

Talking about misdiagnosis, the most obvious misdiagnosis that you are likely to commit is to ignore the following failures:

• Failing radar sensor
• Debris all over radar sensor
• Issues with wiring system
