  • Repairing this fault code is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1442 include the estimated repair time of 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors contribute to the overall cost of resolving the p1442 fault code.

The P1442 fault code indicates that the Secondary Air Injection Vacuum Switching Valve Bank is stuck closed. The Engine Control Module (ECM) detects pressure changes in the system to identify malfunctioning parts and stores the Diagnostic Trouble Codes (DTCs). The ECM measures pressure and exhaust pulsation at multiple points in the system to determine the operation of the air injection system and the condition of the Air Switching Valve (ASV).

If the pressure decreases at points A and B, the ECM determines that the ASV No.2 is open.

At points C and F, the ECM analyzes the pressure and exhaust pulsation to determine the pressure pattern of the system. If pressure changes cannot be detected at point B, the ECM operates the system at point D to identify any malfunctioning ASV No.2.

Lastly, at point E, the ECM detects exhaust pulsation to assess the overall condition of the system. In summary, the P1442 fault code indicates a problem with the Secondary Air Injection Vacuum Switching Valve Bank being stuck closed, which can affect the proper functioning of the air injection system.

What are the possible causes of the automobile fault code P1442 and how can I visually inspect them?

If you’re seeing the engine light or service engine soon warning light and have the fault code P1442, there are a few possible causes to consider. One potential culprit could be a faulty Vacuum Switching Valve (VSV) or an issue with the VSV for the air injection control circuit in Bank 1. Another possibility is a problem with the Air Switching Valve or the VSV for the air injection system in Bank 1. Lastly, it could be an issue with the Engine Control Module (ECM). To visually inspect these potential causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins as well.

How does a faulty Vacuum Switching Valve (VSV) contribute to the engine light being ON and what steps can I take to fix it?

If you notice that your engine light is ON or you see a Service Engine Soon Warning Light, it could be due to a faulty Vacuum Switching Valve (VSV). This valve is responsible for controlling the air injection system in Bank 1 of your engine. To fix this issue, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, making sure there are no visible damages. Additionally, check for any broken, bent, pushed out, or corroded pins in the connectors.

Can a damaged wiring harness or connectors be the reason behind the P1442 fault code and how can I identify and address this issue?

If you’re experiencing the P1442 fault code with the symptom of the engine light being on, it could be due to a damaged wiring harness or connectors. To identify and address this issue, start by visually inspecting the related wiring harness and connectors. Look for any signs of damage, such as broken, bent, pushed out, or corroded connector pins. This simple check can help you pinpoint the problem and take the necessary steps to fix it.
