This answer was rated:

2005 CHEVY COLORADO 2.8 2WD I HAVE CODE C0035 (LEFT FRT SPEED SENSOR SIGNAL)REPLACED SENSOR STILL HAVE SAME PROBLEM WATCHING THE COMPUTER SIGNAL LOOKS ERRATIC COMPARED TO THE RT FRT AND REAR CHECKED ALL CONNECTIONS OK AND CLEAN THERE IS A TSB 3460D BUT CANT FIND IT ANYWHERE.THANKS FOR THE HELP
hi my name is XXXXX XXXXX i can help you with your problem. have you checked the wheel bearing on the left front? sometimes when the bearing starts to go bad it makes the hub move in certian ways that the sensor doesnt pick up the signal. also was there any debris near the sensor when you replaced it? sometimes when you remove the sensor some dirt will fall into the hole and block the sensor. i will try and find the tsb your refering to and post it here for you. hope this helps , please let me know. thanks james

Ok Joe, give me a little time and I will try and find the tsb. Check back in a little while. Thanks James
hi joe, ok i found some information. i had a few references to code c0035 , it seems that chevy has had problems with the left front wheel brg and speed sensor assembly. the recommened fix is to replace the entire assembly. if you do this i would suggest getting a factory part. i hope this helps , please let me know if you have any questions on replacing the assembly. james
