Sensor Type | Output Signal Characteristic | Air Gab | LOW Signal Detecting Voltage | HIGH Signal Detecting Voltage |
Hall effect type | 0V ~ 5V Digital signal output | 0.5 ~1.5 mm | Below 2.0V | Above 3.8V |
Fig.1) This shows waveform of CKPS and CMPS simultaneously. The middle area indicates reference points of CKPS and CMPS.
☞ Injection sequence is determined based on Low and High signal of CMPS reference point as detecting cylinder position.
CMPS signal waveform analysis.
ECM recognizes High signal as Low signal when CMPS signal drops below 2.0V and Low signal as High signal when CMPS signal rises above 3.8V.
V0 - the Minimum voltage of Low signal does not drop below 0.0V due to the hall sensor inside resistance. When the Minimum voltage of Low signal is above 0.6V during signal waveform inspection, check excessive resistance inside of CMPS component or in ground circuit.
