What happens if the EVAP test fails again?
If the decay rate is more than a calibrated value, the control module will rerun the test. If the test fails again, a DTC P0442 will set. If the evaporative emission (EVAP) vent system is restricted, fuel vapors will not be properly purged from the EVAP canister.
Why is my EVAP failing to get I / m readiness?
I just want to get my 06 9-7x 5.3L to pass the e-test, which is just a check for no codes and I/M readiness. All systems have to run through the required cycles and have passed. My evap is failing to complete. I’m not getting any DTC codes, no MIL, just keep getting “Incomplete” for the evap system in Torque.
How does the control module test the EVAP system?
The control module uses several tests to determine if the EVAP system is leaking. This tests for large leaks and blockages in the evaporative emission (EVAP) system.
When does the ECM command the EVAP purge solenoid?
The ECM commands both the EVAP Purge Solenoid and the EVAP Vent Valve ON when the conditions are met in order to apply an engine vacuum to the EVAP system. The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum.
Why do I have an error code on my EVAP system?
Because the entire fuel and EVAP system need to be completely sealed in order for the EVAP system to work effectively, even a slight hole or crack in a single component could trigger the error code. You’ll need to carefully inspect your entire EVAP system:

Is there a code for ABS and ESP?
Yes the codes are valid. Jack up the left front wheel and remove tire and on the rear of the steering knuckle you will see L6/1. Check wire cable for any damage. If not then remove the bolt and try to remove the sensor by twisting it back and forth. Do not use screw driver to pry it up, spray with Liquid Wrench and try again.
What happens if the ABS coding is wrong?
Click to expand… As best I know, the ABS coding for a given car should not change when the correct replacement part is installed. If the coding is wrong, one would expect a 01042 – Control Module; Not Coded or something to that effect to be flagged. Thus, so far, so good.
