2004 Chevrolet Malibu Q&A
2004 Chevrolet Malibu Question: do the pass lock sensor is a part of the anti-theft system?
They lied. The passlock sensor is part of the Anti-Theft system (or Immobilizer as they are called now). If the sensor is bad, the Theft Light will come on and the Cranking, Spark and Fuel delivery can all be disabled (depending on year/make/model). - ChevyASE
