Input/Output Signal Chart
WARNING: This page is about a different car, the 2015 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
| Sensor | Input signal to ECM | ECM function | Actuator |
|---|---|---|---|
| Crankshaft position sensor (POS) | Engine speed * 2 Piston position |
Ignition timing control | 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 | ||
| Knock sensor | Engine knocking | ||
| TCM | Gear position | ||
| Battery | Battery voltage * 2 | ||
| Wheel sensor | Vehicle speed*1 |
*1: This signal is sent to the ECM through CAN communication line.
*2: ECM determines the start signal status by the signals of engine speed and battery voltage.
