[SOLVED] P2258 Code: How To Fix High Circuit In Secondary Air Injection System

The P2258 fault code in automobiles indicates a problem with the secondary air injection system. The most common symptom is the illumination of the engine light or service engine soon warning light.

The cause of this fault code could be a faulty secondary air system relay, an open or shorted harness, poor electrical connection, or a faulty secondary air system pump.

It is important to address this issue promptly as it can lead to increased emissions and reduced engine performance. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time for this issue is estimated to be around 1.0 hour.

If you notice the engine light on or service engine soon warning light, it could be a sign of p2258 fault code.

Here are the symptoms to look out for:

  • The P2258 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include a decrease in engine performance, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience reduced fuel efficiency, increased emissions, and a decrease in overall power.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

There are several causes of the automobile fault code p2258, including a faulty relay and poor electrical connection.

  • The automobile fault code P2258 can be caused by a faulty Secondary Air System Relay.
  • It can also be caused by an open or shorted Secondary Air System Relay harness.
  • Another cause can be a poor electrical connection in the Secondary Air System Relay circuit.
  • Lastly, a faulty Secondary Air System Pump can also trigger this fault code.

To fix the p2258 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2258, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2258 indicates an issue with the secondary air injection system. The diagnosis and fixing cost of this fault code is influenced by the estimated repair time, which is 1.0 hour. The cost of repair is also affected by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

These factors should be considered when estimating the total cost of diagnosing and fixing the P2258 fault code.

The P2258 code refers to the Secondary Air Injection System Control ‘A’ Circuit High. The Air Pump is used to lower tail pipe emissions on start-up.

The Powertrain Control Module (PCM) grounds the Air Pump Relay Control Circuit which energizes the Air Pump. The PCM also grounds the Air Combination Valve Vacuum Control Solenoid Circuit, which energizes the Air Vacuum Control Solenoid. When the Air System is active, the Air pump forces fresh air into the exhaust stream to accelerate catalyst operation.

The P2258 code indicates that there is a high circuit in the Secondary Air Injection System Control ‘A’.

What are the possible causes of the automobile fault code P2258?

If you see the engine light on or the service engine soon warning light, it could be due to the P2258 fault code. This code is usually caused by a faulty secondary air system relay, an open or shorted relay harness, poor electrical connection in the relay circuit, or a faulty secondary air system pump. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2258 fault code?

If you’re experiencing the P2258 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you can fix it by visually inspecting the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This fault code can be caused by a faulty Secondary Air System Relay, an open or shorted Secondary Air System Relay harness, a poor electrical connection in the Secondary Air System Relay circuit, or a faulty Secondary Air System Pump.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P2258 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P2258 fault code, follow these steps: Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. If you find any of these issues, replace or repair the damaged components and pins. This will help to fix the P2258 fault code and turn off the Engine Light or Service Engine Soon Warning Light.
