Signal to low Car is in limp mode. Symptoms: If I take throttle body connector off car starts but is limp mode. When connector is connected car wont start because valve shuts. Lamda has freezed value sama first heat sensor in cat Throttle pedal sensor is giving 8-25% normal 0%-99% Done: Dpf taken off, fysical and remap EGR Remapped Swirlflaps remapped. Ecu cloned and changed. First tempture sensor in cat replaced. Frozen value didnt change I have checked all wirings from ecu to sensors in 5v circuit. Im curios what gives the signal to throttle body to shut when i start the car Last edited by zimppari; Feb 3rd, 2020 at 16:27.
