P2258 - OBD Trouble Code

<<See All OBD Codes

The OBD-II Code P2258 is stated as a Secondary Air Injection System Control "A" Circuit High.

The Secondary Air Injection System pushes exterior clean air into the Exhaust System throughout a cold engine start up. This extra air assists in burning up the ultra profuse exhaust fumes that are created when the engine is warms up. The Secondary Air System usually obtains an Air Pump and a few tubes or a plumbing system to source the air. The system also consists of a solenoid and Check Valve(s) to manage this airflow. As the engine control module (PCM) finds a defect with the Secondary Air Injection System, it will prompt the P2258 code to be set.

As the P2558 code shows up, the engine control module (ECM) has situated a problem with the secondary air injection system control circuit. The secondary air injection system helps with decreasing a vehicle’s fumes by doing air pumps into the exhaust stream when there is a cold engine, which assists with accelerating the procedure of heating the catalytic converter. This code shows up more frequently in cold temperatures.

The vehicle’s ECM holds both the air combination valve vacuum control solenoid circuit, including the air pump relay control circuit. Whenever the ECM scans a voltage message out of over 10 percent of the permitted quantity, it will store the code P2558.

What causes this problem with the Secondary Air Injection System Control "A" Circuit High?

• Broken or faulty one-way check valve
• A shorted or open secondary air system relay harness
• A wrecked or defected system relay
• Destroyed or incorrect electrical circuit connections
• Defaced or impaired solenoid
• Broken or defective air system pump

1. Air Injection System - The air injection pump system is equipped to assist with decreasing the emissions coming out of the exhaust and can cause the vehicle to fail emission testing. The check engine light blazing on also has an outcome of the vehicle failing to test the emission. If the system was poorly bypassed, such as the component that rusts right off, then it has the ability to end up robbing the drivetrain of an output. If any loose ends, leaks, or other kinds of erratic airflow are found, the engine is wasting its power. The smog pump presents air that meets up with the exhaust after it comes out of the engine, so assuming that all works properly, the smog pump puts an affect on the car's performance, since maintaining the right pressure around the entire exhaust system is crucial for smooth running.
2. Air Pump - A negative or failing smog pump is an important symptom that causes a rough running engine. When a smog pump fails the finely tuned air-fuel ratios can be a problem, and it will badly affect the engine operation. The engine may tackle with idling, and could plummet during engine acceleration, or stall when the pedal is pressed. A negative air pump might also result in a reduced power output that is outside the engine. Once again, a failing smog pump can tamper with the tune of the vehicle, which will put a negative effect on the uppermost engine operation. A failing air pump may cause the engine to stall or stumble when accelerating, and in more serious cases, cause an identifiable reduction in total power output. If you suspect that your air pump could be dealing with a problem, or your Check Engine Light has come on, have an experienced mechanic diagnose the vehicle.
3. Powertrain Control Module - Erratic engine behavior might detect a poor or failed ECM. A failed computer could result in a vehicle that stalls unpredictably or fails in starting. If the ECM is dealing with any errors, it could resist the timing and fuel positions of the engine that could put a bad effect on the vehicle as it is processing. A failed ECM results in a vehicle that deals with a decrease in fuel efficiency, power, and speed. A failed ECM could be faced with a vehicle that is failing to get started or is dealing with problems in restarting. If the ECM is failing entirely, the vehicle remains dealing with that lack of engine power control, so it could fail to start or face issues when running as an outcome. The engine could still crank, but have no critical inputs coming from the computer, so it is bound to not start altogether.
4. Engine Control Module - The Engine Control Module (ECM) might fail if damage or corrosion reaches the inside wiring positions in the injector wiring harness or the sensor wiring harness, which causes a short in the ECM, or corrosion spreads out into the ECM and flows in through the wiring harness. This happens even when coming in contact with a wide range of outdoor elements that tamper with the vehicle’s components.
5. Air Injection Control Valve - If no airflow enters the exhaust stream, the startup emission levels will hike up. The control module can detect for a system stream problem by using the pre-catalyst heated oxygen sensor (HO2S) and short term Fuel Trims. If a system stream problem is present the HO2S voltage will not display an expected lean condition, short term Fuel Trim will not increase and a diagnostic trouble code (DTC) will get set. If incorrect voltage is present on the vacuum control solenoid or the pump relay control circuits the device will not be running. The control module will detect this and a DTC will get set.
6. Vacuum Hose Relay - When a vacuum hose fails or leaks, another effect that occurs is an engine that is running very rough. This is normally viewed as an engine misfire or an inconsistent idle RPM. Normally the Check Engine Light will illuminate when this problem occurs, though it’s probably the sensor that can have issues, which bypass this warning. In this case, the driver is frequently the best source of viewing issues that are activated by vacuum hoses. If you can see that the engine runs rough at idle, acceleration or deceleration, then contact your local certified mechanic so they can inspect the problem and adjust the relay before it gets to be a major error or causes even more engine damage. A backfire is normally the cause of a malfunction in the electronic timing system that sends input with every spark plug in order to fire at an approximate time. The backfire can also cause an increase of combustion chamber pressure, which is managed by vacuum hoses and sensors. Backfires are not a good idea on engine components and if not solved with success, can cause a disastrous engine failure. If you are dealing with a backfire at any moment, you should contact an experienced mechanic so they can test-drive the vehicle and if in need, diagnose the approximate error and make the correct repairs to solve this troubleshoot.
7. Air Pump Relay - An engine that stalls is a major error with the fuel pump relay. If the fuel pump relay has an error when the vehicle is performing, it will obstruct power to the fuel pump, which will cause the engine to stall. A failed relay may allow the vehicle to restart a short any time later, while a relay that failed completely will not. An engine that is failing to start is another error with a failed fuel pump relay. If the fuel pumps relay fails, this leaves the fuel pump with a lack of power. The engine could still be cranking when the key is turned, moreover it will fail to start due to a lack of fuel. Multiple other errors will cause this symptom; so ensuring the vehicle is properly diagnosed is strongly advised. A problem with the fuel pump relay might also be a noise that comes from the fuel pump when the key is turned on. Most of the fuel pumps will produce a low volume hum or whine sound that can simply be heard from the inside of the vehicle if carefully listened to, or from the outside of the vehicle, nearby the fuel tank. If the fuel pumps relay fails, it will cut off power to the fuel pump, which will be displayed as inoperable, and therefore quiet, when turning on the ignition.
8. Exhaust System - If you start to feel your vehicle is vibrating during the ride, even when idling, it might be an indicator of exhaust system failure. You’ll have to get your exhaust system detected to make sure there is nothing plugging the exhaust system before we can determine that your exhaust system is actually failing. A rumbling noise that appears to be coming out of the exhaust pipe or muffler is another possible sign of exhaust system failure and can often be attended with a feeling of vibration you are able to feel when something is wrong with your vehicle’s exhaust. This symptom on it’s own, excluding vibrating feeling, is still sufficient to permit a detection. In spite, there can be a number causes for lower fuel efficiency; a major cause is exhaust system failure. Since your exhaust system is keeping your vehicle’s engine from running effectively, and as it’s failing, your vehicle will conduct more negatively than it’s expected to, and you might see a reduction in fuel efficiency. An exhaust leak is a certain indicator that your exhaust system is failing, so if you see an exhaust leak, take consideration of how negative the leak is so that your ware of how widespread the damage could be. On all vehicles with a catalytic converter, a problem with the catalytic converter can result in exhaust system failure. If your exhaust system failure is indeed is being caused or worsened by an issue with the catalytic converter, take a glance for these following symptoms: Metallic-rattling noises coming from the exhaust pipe. If you have a catalytic converter error that results in an exhaust system failure, you might be listening to a metallic rattling sound that is coming from the exhaust pipe, specifically when it idles.
9. Air System Pump - The air system pump is not working after cold start. There is a burning smell coming out of the engine compartment. There are electric contacts of the air system pump that are burned. The air system pump might have failed because of an overload. You can determine about how all of these symptoms happen right here. The relay is obstructed by way of how the air system pump is being controlled. As an outcome, the air system pump has been activated for long duration of time that is too bad to be allowed. Throughout a cold start, the air system pump might only be performing for an ultimate time frame of 90 – 120 seconds.

It is essential to learn all about the symptoms of a problem, so that you will manage to solve the error. This is why our team has written out a few major symptoms of OBD Code P2258 below:

Common Symptoms

• The light might remain turned on or light erratically as the DPF processes. The engine will be slow when speeding up.
• Defective PCM
• If not clearing the DPF this will revert the ECU to the Limp Home Mode until correcting the situation.
• Profuse or meager exhaust

These Symptoms might come as erratic sounds coming from the secondary air injection system; the engine delays when speeding up, the engine might stall when starting up or idling, a is being stored, and a malfunction indicator lamp finally illuminates.

Are you eager to correct the Error Code P2258? Follow these steps as described below:

• The sensor is provided with a low voltage, normally 5-volts, power wire and a ground wire.
• When turning the input shaft, by way of the engine, the electromagnetic input/turbine speed sensor utilizes the spaces set between the splines to give voltage signal disruptions in the circuit.
• A few vehicle programs also use the inlet door to control airflow in past the intake tube by repairing the extent to that the door opens in a matter corresponding to positioning the throttle.
• A number of tools will be contributory in achieving the diagnosis of the code.
