1995 FZJ80. Time to smog in CA. I have had the P0402 code for years, I usually just disconnect the battery before going in for smog and it passes.
This time around, the Torque app was saying that I wasn't passing the Catalytic convertor and the EGR readiness codes. My mechanic took temp readings on the cats and said that they definitely weren't working right because of the temperatures that he was getting. We changed out the Cats to new CA compliant units
I also ordered the HUD Expo EGR deal so that the CEL light would not turn on due to the EGR.
All of the emission monitors have cleared except for the Cats and the EGR. I was under the impression that the HUD Expo EGR dongle would allow the EGR readiness to pass, but apparently I misunderstood the point of this piece.
I have driven about 60 miles so far in varying conditions and the cats will not achieve a ready status.
first question: Will the EGR not passing readiness cause the cats not to pass?
second question: If the EGR isn't causing the Cats not to achieve readiness, what can I do to get the cats to pass? Just keep driving? I have done several freeway passes at 60 mph and a few drives around town. My mechanic is very confident that it will eventually get there and that I just have to keep driving it around.
really need the cats to pass readiness so that I can smog and drive the 80. tags are now expired, so no driving it until then.
any help here is greatly appreciated. I did search the topic and did some reading, but none of the posts touch on the EGR situation as it may or may not apply to the cats passing readiness.
