you mean multiple sensors? with the 2.4 there is only 2 sensors. I checked the sensors for resisitance and they check okay as per service manual but we'll say something is on sensor one (upstream) that wouldnt change the value of the resistance I think. I think if sensor one was coated in soot it would make it rich making sensor two high voltage?

I am wondering about my vacuum system in it to. I can sit at a stop light, and just stretch my leg pressing the brake pedal and I can set of the stability control. it'll beep and the light of the car with skid marks under it will light up. can reproduce it 100%
