Impulse sensor, specifications
The inductive sensor gives engine control module (ECM) information about the crankshaft's position and speed.
The values should be regarded as approximate.
| Type | Voltage feed (# component pin) | Value (# component pin) | Miscellaneous (# component pin) |
|---|---|---|---|
| Hall sensor | 125.5 17 ohms at 20°C (#1 - #2) |

| Temperature, °C | Resistance ohms | Voltage, V |
|---|---|---|
| 0 | 6000 | 1.55 |
| 10 | 4000 | 2.01 |
| 20 | 2450 | 2.62 |

Intake air temperature (IAT) sensor inlet
Knock sensor, specifications
The knock sensor gives engine control module (ECM) information if it registers damaging knocking ignition. Some engines have both a front and rear knock sensor.
The values should be regarded as approximate.
| Type | Voltage feed (# component pin) | Value (# component pin) | Miscellaneous (# component pin) |
|---|---|---|---|
| Piezo-electric crystal | 200 80 kohms (#1 - #2) | (#1) + (#2) |
Knock sensor
Mass air flow (MAF) sensor, specifications
The mass airflow sensor gives engine control module (ECM) information about the air mass that passes through the sensor, which then is sent into the engine as well as the temperature of that air.
The values should be regarded as approximate.
| Type | Voltage feed (# component pin) | Value (# component pin) | Miscellaneous (# component pin) |
|---|---|---|---|
| Combined mass airflow sensor with air temperature sensor | 12 V (#1) (air mass) 5 V (# 4) (air temperature) | 1 V = 1.3 g/s at 20°C 4.4 V = 170 g/s at 20°C (#3 - #2) 16 kohms at -20°C 6 kohms at 0°C 2.5 kohms at 20°C 0.6 kohms at 60°C (#4 - #5) | (#2) signal ground (air mass) (#3) output signal (air mass) (#5) signal ground (air temperature) |
Mass air flow (MAF) sensor
| Mass air flow (g/s) | RPM at unloaded engine, warm engine (RPM) | (V) | (# component pin) |
|---|---|---|---|
| 3,3 | 850 | 1,3 | (#3 - #2) |
| 5,7 | 1500 | 1,6 | (#3 - #2) |
| 7,3 | 2000 | 1,7 | (#3 - #2) |
| 9,3 | 2500 | 1,8 | (#3 - #2) |
