P0340

WIRING DIAGRAM

SYSTEM DESCRIPTION
CMP sensor detects REF signal and POS signal.
- REF signal: 6 pulses/1 revolution of camshaft. Each of REF signals has different wavelength. Based on REF signal, ECM (PCM) judges which cylinder is at TDC.
- P05 signal: 360 pulses/1 revolution of camshaft. Each of P05 signals has equivalent wavelength. Based on P05 signal, ECM (PCM) judges the wavelength of REF signals, engine speed and piston position.
