Had the CTT-S checked at the dealership about 2 weeks ago.. CEL cleared (reset), then came back again today.. is this normal? CEL is not blinking, still gets full boost (up to 0,8 bar)

The previous issue was: Mechanical fault in EVAP canister purge valve (does not close fully) - Is this code something that can be "set" via durametric?

Also, would a durametric cable/software give a specific and/or detailed information of what's causing the CEL compared to using the OBD-II code reader in Autozone? Was hoping that this is the same issue as before (re: EVAP canister purge valve). I am deliberating if I need the durametric cable to reset this, or go to the dealership to reset (hopefully free of change - again), and go to autozone to read the code if I get the CEL again.

Thanks in advance...

 

You can clear the light by pulling fuses to the ecm in the underhood fuse compartment, but, it will just come back because neither you or the dealer have fixed the problem. When the fault is emissions related, the light will be continuously lit. When it is engine related it will flash and you will probably get a warning message on the cluster screen. Look in the owners manual for a legend to the underhood fuse panel. Emissions related faults usually have to have the fault condition present upon multiple keystarts b4 the cel comes on.

 

thanks Mr. Haney.. it seems that the problem is with the EVAP purge valve canister and have to replace that.. got advise from the other forum that this is an easy DIY fix.. got the part number 948 110 202 01...
