can u get a flase catalitic converter coad after replacing a bad sensor?
I brought my car in BC the check engain light was on. I was told it need a new sensor so I had it replaced for 240,00. I left the shop and within 5 miles of driving the light came on. Took it bach to the shop and was told it's on now bc it needs a catalytic converter. I assume he turned the light out. It has not been on since so I asked today did he disable it. I was told no the catalytic converting read was because the sensor was bad the 2nd rear sensor couldn't read anything so when the 1st was repaired it tripped a faluse reading. Is this true?
