Error Code P2592: What It Means & What To Do?

<<See All OBD Codes

The trouble code P2592 can be explained as Cruise Control Front Distance Range Sensor Right. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile. This type of error code is exhibited exclusively in automobiles equipped with adaptive cruise control systems.

If the engine control module would detect a variation in the voltage coming from the right front distance range sensor for the adaptive cruise control system that is outside the parameters set by the automobile manufacturer, then it would store the P2592 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Cruise Control Front Distance Range Sensor Right?

• Some issues related to the front distance range sensor right
• Unlocked front distance range sensor right harness
• Unsatisfactory electrical connection in the front distance range sensor right circuit

1. Turbocharger - When the boost is running, a faulty turbo could make a loud whining noise. The noise generally sounds like a siren, and it tends to get louder as the issue aggravates. If you notice an uncommon noise paired with some of the above symptoms, your turbo might be failing. Visit us to purchase top notch turbocharger online.
2. Throttle Position Sensor - Are you experiencing sudden idle surges and sudden hesitation while accelerating? Then these are the symptoms of defective throttle position sensor. Get it checked and replace if needed.
3. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
4. Engine Coolant Temperature Sensor - The most common symptom which is associated with the issues in the engine coolant temperature sensor is the poor fuel economy. Reduction in the fuel economy would also hinder engine performance. Purchase top notch engine coolant temperature sensor online.
5. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
6. Exhaust System Parts - Are you seeing this error code flashing? Well, it could be due to malfunctioning exhaust system parts. In addition to this error code, the driver is likely to experience a noisy engine, decrease in power and acceleration. We strongly recommend you to purchase new exhaust system parts from Parts Avatar.
7. Electronic Control Unit - Is your car jumpstarting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So, it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2592 code to be stored:

The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle. The vehicle 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.

When 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.

Repair or restore the defective, disconnected, shorted, or corroded wiring, connectors, and components as per the requirement. 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 the 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. Then the 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 the entire system should be retested.

Common Mistakes When Diagnosing The P2592 Code

• There are many technicians which do not check the blown fuses after they have replaced the defective components. Often a lot of components are unnecessarily replaced due to a blown fuse.
