I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


here is what i found on p1416.



P1416 Chevrolet
P1416 Chevrolet - Secondary Air Injection System Bank 2
Possible causes
- Faulty Secondary Air Injection (AIR) pump
- Secondary Air Injection check valve bank 2
- Secondary Air Injection (AIR) pump electrical circuit fault
- Blocked Secondary Air Injection (AIR) system

When is the code detected?

The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)


P1416 Chevrolet Description
An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

Showing p0741 and the sevice engine soon light is on


The "Service Engine Soon" light, or "Check Engine" light is how a car alerts the driver of any problems related to its central computer. The ECM, or Electronic Control Module, controls the vehicle's engine and transmission. The service engine light warns if there is anything preventing the engine from, "running at top efficiency with the lowest possible emission," according to Samarins.com. ----------------------------------------------------------------------------------------

Sevice Vehicle Light


The service vehicle is not the same as the service engine light in that the service vehicle light has to do with the body control module,(BCM).You have to get the codes read for the BCM and any other module with the scan tool.I`m not sure if Auto Zone can read the BCM codes.Not all scan tools are able to read all the modules in a vehicle.Hope this helps.Good luck.
