Input/Output Signal Chart
| Sensor | Input signal to ECM | ECM function | Actuator |
|---|---|---|---|
| Crankshaft position sensor (POS) | Engine speed* 3 Piston position |
Ignition timing control | Ignition coil (with power transistor) |
| Camshaft position sensor (PHASE) | |||
| Mass air flow sensor | Amount of intake air | ||
| Engine coolant temperature sensor | Engine coolant temperature | ||
| Throttle position sensor | Throttle position | ||
| Accelerator pedal position sensor | Accelerator pedal position | ||
| Park/neutral position (PNP) switch* 1 | PNP signal | ||
| Transmission range switch* 2 | |||
| Battery | Battery voltage* 3 | ||
| Knock sensor | Engine knocking | ||
| Combination meter | Vehicle speed* 4 |
* 1: M/T models
* 2: A/T models
* 3: ECM determines the start signal status by the signals of engine speed and battery voltage.
* 4: This signal is sent to the ECM through CAN communication line.
