I couldnt get it to pass emissions because of the check engine light. Originally showed P 410 I replaced the secondary air injection pump and the check engine light is still on. When we put a scaner on it, it does not show any trouble codes. I finaly got the state to pass it for me, but I want it fixed. Any help?

For some of the emission systems the PCM may need to see an issue two or three times before the PCM will set a hard fault code?
In other words the computer may need to see an issue with this (or whatever) system two or three times consecutively; while performing self tests, before it will store hard codes.
The PCM will however store a pending code the first time it sees this kind of fault; many of these cheep-o code readers cannot read or display pending codes; but if there’s a light on, there’s a code set somewhere in one of the computers.
Again a pending code is something that the PCM has seen that’s not right; but waits to see if it is a continuing issue or just a one time fluke. The PCM will also erase a pending code, after a predetermined number of passes, during self testing.
Depending on what system is at suspect; the PCM may or may not turn the check engine light on; when a pending code is warranted?
So if you want this fixed; I’m going to suggest taking the vehicle in and have it properly scanned and diagnosed by a technician?
The test procedure for the 410 code is something like 43 steps long and will take you in as many different directions? It is all dependent on the outcome of each individual step, of the test procedure.
At the same time this may not have anything to do with the AIR (Air Injection Reaction) system it self? The computer could be setting a 410 because during the self test of the system; the results are falling into the parameters for setting the code; because of (for example only) a lazy O2 sensor not providing fast accurate information?

Thank you for help. I forgot to tell you in the OP that the PCS light is on also. Make any difference in this situation, or is that going to be a whole different issue?

PCS is the Precision Control System (a form of or part of the traction control system) and is controlled by the EBCM (electronic break control module) and likely will not have anything to do with the PCM. When that light comes on, it’s telling you that the PCS system has been shut down; due to the EBCM has seen a fault. It usually will also turn on the trac (if it has one) or the ABS light along with it?
Again a basic code reader cannot access the EBCM.
