Air pressure sensor intake manifold (MAP), specifications
Air pressure sensor intake manifold (MAP) gives the engine control module (ECM) information about the pressure of the air being sent into the engine.
The pressure is given in kPa and sinks with increased engine load (vacuum).
The values should be regarded as approximate.
| Type | Voltage feed (# component pin) | Value (# component pin) | Miscellaneous (# component pin) |
|---|---|---|---|
| Absolute manifold absolute pressure (MAP) sensor | 5 V (#3) | 3.6 V = 101 kPa 3.3 V = 90 kPa 2.7 V = 70 kPa 2.1 V = 50 kPa (#1 - #2) | (#1) output signal (#2) signal ground |
Air pressure sensor intake manifold (MAP)
A/C pressure sensor, specifications
The sensor gives the engine control module (ECM) information about the pressure in the air conditioning (climate unit).
The values should be regarded as approximate.
| Type | Voltage feed (# component pin) | Value (# component pin) | Miscellaneous (# component pin) |
|---|---|---|---|
| Absolute manifold absolute pressure (MAP) sensor | 5V (#1) | 0.25 kPa = 0 V 517 kPa = 1 V 1206 kPa = 2 V 1894 kPa = 3 V 3100 kPa = 4.75 V (#2 - #3) | (#2) output signal, (#3) signal ground |
