A system for a vehicle includes a cylinder pressure sensor and a control module. The cylinder pressure sensor measures pressure within a cylinder of an engine, generates increases in a cylinder pressure signal based on the pressure, selectively generates a predetermined profile in the cylinder pressure signal, and selectively resets the cylinder pressure signal to a predetermined reset level after generating the predetermined profile in the cylinder pressure signal. The control module receives the cylinder pressure signal, detects the predetermined profile of the cylinder pressure signal, and detects the resetting of the cylinder pressure signal to the predetermined reset level when the predetermined profile is detected.
