I just bought a 2001 s-10 2.2 5 speed manual. Ive done countless drive cycles but cant get the secondary air and evap to pass. The vent solenoid is actuating and the secondary air pump is working. All fuses are good. No check engine light and no active or pending codes. What could be the problem?
Do you have the capability to see what dtc tests have run and passed, and/or run and not passed? It should be available on the scan tool. Once you have determined which have either not run, or not passed, you can look at the criteria for running the test, and see if there are specifics that are not being met.
Here is the typical drive cycle that I have shown, see if there is anything different than what you are doing.
