Code P1416 typically indicates an issue with the secondary air injection system, often related to a malfunctioning air pump or a blockage in the system. To fix it, start by inspecting the air pump and the associated hoses for damage or leaks. Additionally, check the electrical connections and fuses related to the air injection system. If necessary, replace any faulty components and clear the codes to see if the issue is resolved.
Look for a leak in the port-side vacuum.
Trouble code P1416 means:Secondary air injection (AIR) system
Trouble code P1416 means: AIR System Bank 2
Replace the check valve on the secondary air injection system on the passenger side
this is the O2 censors
The P1416 code on a 2001 GMC Sierra typically indicates a problem with the secondary air injection system. To fix this issue, first, inspect the air pump and its relay for proper operation and check for any vacuum leaks in the hoses connected to the system. Additionally, examine the air injection system's check valves for blockages or failure. If components are damaged or defective, replace them, and clear the code to see if it reappears after the repairs.
P1416 is your O2 censors. ANSWER: P1416 refers to a problem in the exhaust system which is, unfortunately, very difficult to track down. Depending on who you talk to about it, you can do nothing and never have a problem or you can do nothing and it can ultimately lead to a problem with the catalytic converter. Damned if you do and damned if you don't.
Air Injection Check Valve ( Passenger side bank 2)
Replace airpump check valve on passenger side of secondary air system.
you have a leak in the port side vacuum. try spraying choke cleaner with the straw on the end around the vacuum lines with the engine running, when you hear the engine rpm raise you just found the leak....
Code P1416 typically indicates an issue with the secondary air injection system, often related to the air pump or its control circuit. To repair it, first inspect the air pump, hoses, and electrical connections for any damage or leaks. Additionally, check the relay and fuses associated with the system. If these components are functioning properly, further diagnostics may be needed to assess the vehicle's computer and associated sensors.
That code indicates a problem with the AIR system, bank 2. Bank 2 is the passenger side of your car. It is most likely the check valve on the passenger side. It can be cleaned, or cheaply replaced.
