From what I've seen through searches this seems to be a common problem, what I haven't been able to find yet is a solution. When I went for my emissions inspection I have 3 sensors failing because they indicate not ready, I need 2 or less to pass. I tried driving lots of miles, that doesn't do anything. I also tried a generic drive cycle reset:
1. cold start, idle at 2500rpm for 15 seconds then 4000 rpm for 15 seconds
2. run at 55mph in 5th gear for 1 minute, then come to a stop.
Which also didn't change anything. Would disconnecting the negative battery cable and stepping on the brake pedal to reset everything be of any help? I'd like to find a cheap solution before resorting to a shop if at all possible. I have a 1998 Protege 1.5L that runs like a dream except for this problem. Thanks
