Having problems with your 1997 Toyota Tacoma ?
2001 TACOMA, 2.7 ENG., 4WD, REG. CAB, STNDRD. CHECK ENG LIGHT CAME ON AND READ; CATALYST BELOW EFFICIENCY LEVELS, BANK 1. REPLACED THE CONVERTER WITH AN OE STYLE AFTERMARKET. LIGHT CAME BACK ON THE NEXT DAY. THEN REPLACED DOWNSTREAM SENSOR WITH AFTERMARKET TYPE. LIGHT CAME BACK ON IN 6 DAYS. THEN REPLACED UPSTEAM SENSOR. LIGHT CAME BACK ON IN 3 DAYS. A MECHANIC FRIEND TOLD ME THAT THE COMPUTER PROBABLY WASN'T RECOGNIZING THE AFTERMARKET SENSORS. BOUGHT DOWNSREAM SENSOR FROM DEALER [VIN MATCHED]
I know you have heard this before already but the converter that you had installed is your problem you need the oe one from the dealer.O2 do not fix this code i know because this is what i do and have in the past been burnt by not putting in the correct converter thinking the o2 will fix it when the 2 cars came back but no more getting bit.:)
Could be faulty computer. What engine codes have you gotten after you replaced the parts and reset computer?
