The P2259 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 decreased fuel efficiency.

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.

Here are the symptoms to look out for:

  • The P2259 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, and stalling.
  • Additionally, the vehicle may experience difficulty starting, and there may be a noticeable decrease in acceleration.
  • 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 p2259, including a faulty relay and poor electrical connection.

  • The automobile fault code P2259 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 p2259 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2259, you need to 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.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2259 indicates an issue with the secondary air injection system. The diagnosis and fixing cost of this fault code is influenced by several factors. The estimated repair time for this fault code is 1.0 hour.

The cost of repair is also influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour. Other factors that may affect the cost include the severity of the issue, the type of vehicle, and the availability of replacement parts.

The P2259 code refers to the Secondary Air Injection System Control ‘B’ Circuit Low.

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 P2259 code indicates that there is a problem with the Secondary Air Injection System Control ‘B’ Circuit Low.

What are the possible causes of the automobile fault code P2259?

If you see the engine light on or the service engine soon warning light, it could be due to the P2259 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.
