#138313, "RE: Car goes into open loop near 0 vacuum" In response to In response to 8
Well today I completely disconnected the FCD and disconnected the intercooler piping, to take the turbo aspect out of the equation. And it still goes to open loop on the freeway while cruising, if the vaccum moves past -3.0 PSI to -2.9 psi. The car goes back into closed loop if I back off the throttle just a hair so the vacuum increases to -4.0. I logged everything, but can't find any sensor that's tripping the switch to open loop. I thought there might be noise on the TPS wire giving a fast false "WOT" signal to the ECU, but even with 0.1 second sampling I never catch one of these events.
