The P2435 fault code in automobiles refers to 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 issue could be a faulty Secondary Air Injection Pump Relay, a faulty Secondary Air Injection Pump, an open or shorted Secondary Air Injection Pump harness, or a poor electrical connection in the Secondary Air Injection Pump circuit.

The repair importance is high as it can lead to increased emissions and reduced engine performance. The difficulty level of the repair is moderate, with a repair time of 1.0. To fix the issue, one should visually inspect the related wiring harness and connectors and check for damaged components and connector pins.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2435 fault code.

Here are the symptoms to look out for:

  • The P2435 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, decreased engine performance, rough idling, engine stalling, and decreased fuel efficiency.
  • It can also cause the engine to emit unusual noises and vibrations, and the exhaust system may emit smoke or unusual odors.
  • If you experience any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic to diagnose and repair the issue.

The automobile fault code p2435 can be caused by a faulty relay, pump, harness, or poor electrical connection.

  • The automobile fault code P2435 can be caused by a faulty secondary air injection pump relay.
  • It can also be caused by a faulty secondary air injection pump.
  • Another cause can be an open or shorted secondary air injection pump harness.
  • Lastly, a poor electrical connection in the secondary air injection pump circuit can also trigger this fault code.

Listed below are possible fixes for the automobile fault code p2435, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2435, 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 automobile fault code P2435 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of fixing the P2435 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2435 code is related to the secondary air injection system.

This system helps to reduce hydrocarbon emissions during a cold start.

The pressure sensor in each shutoffcheck valve monitors the air flow from the secondary air injection pump. The ECM controls the relays that activate the pump and valves.

The DTC will set when the pressure sensor value change at either shutoffcheck valve is not to factory specification when the air injection pump is commanded ON.

What are the possible causes of the automobile fault code P2435?

If you see the engine light on or the service engine soon warning light, it could be due to the P2435 fault code. This code is caused by a faulty secondary air injection pump relay, a faulty secondary air injection pump, an open or shorted secondary air injection pump harness, or a poor electrical connection in the secondary air injection pump circuit. 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 P2435 fault code?

If you’re experiencing the P2435 fault code, start by checking the possible causes listed above. To visually inspect the related wiring harness and connectors, look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues with the Secondary Air Injection Pump Relay, Secondary Air Injection Pump, or poor electrical connection in the Secondary Air Injection Pump circuit.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P2435 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P2435 fault code, follow these steps: visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify the cause of the issue and allow you to fix it accordingly.
