INPUT/OUTPUT SIGNAL CHART
| Sensor | Input signal to ECM | ECM function | Actuator |
|---|---|---|---|
| Crankshaft position sensor (POS) | Engine speed*1 Piston position |
EVAP canister purge flow control | EVAP canister purge volume control solenoid valve |
| Camshaft position sensor (PHASE) | |||
| Mass air flow sensor | Amount of intake air | ||
| Engine coolant temperature sensor | Engine coolant temperature | ||
| Air fuel ratio (A/F) sensor 1 | Density of oxygen in exhaust gas (Mixture ratio feedback signal) | ||
| Throttle position sensor | Throttle position | ||
| Accelerator pedal position sensor | Accelerator pedal position | ||
| Battery | Battery voltage*1 | ||
| Fuel tank temperature sensor | Fuel temperature in fuel tank | ||
| EVAP control system pressure sensor | Pressure in purge line | ||
| Unified meter and A/C amp. | Vehicle speed*2 | ||
| *1: ECM determines the start signal status by the signals of engine speed and battery voltage. *2: This signal is sent to the ECM via the CAN communication line. |
