Hi there
I have strange issue keep appearing since i replaced my ECU/ PCM from junk yeard. i have like these codes keep appearing. all of them at once P0053 P0054 P0059 P0060. (attached)
I thought Ok! maybe its the O2 sensor is dead and so i changed them all ( all 4 upstream and downstream). still the issue appearing after like 2 days or 3. then i replaced only one thinking maybe the guy who installed them messed them up somehow. still the codes come back! not one or 2 but all of them.
I can see there is volts/ signal on them according to the ODBII just like before i replaced them and the device showing they are active and running fine. also wires are ok.(attached)
what could be the issue?? PCM? maybe i need to re tune it to stock as i can see the fan initiate at early rpm and the IDLE rpm is high? maybe the previous owner was programming the PCM for specific Octane as i read on some sites if the tune is not fixed this might happen?
there is like CAT pop if i rev the car high on stop, i don't think its because of the cats as i know if cats are dead there will be another code.
Car is running Perfect. no issues, no low MPG, no idle issue..nothing at all. its perfect 100% like new . but this fu***n engine light every couple of days is driving me crazy lol.
can anyone advise? otherwise i would go to the dealer and flush the Stock tune as i dont see anything i can do after this point.
