P1442: Understanding The Evaporative Emission System Leak Detection Pump Failure
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.
FAQ
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.
