Turbo pressure gauge
| Turbo pressure gauge |
The main instrument unit has an electronic turbo pressure gauge.
This gauge is supplied with current and controlled by the main instrument unit's control module.
The main instrument unit receives information on the pressure in the intake manifold from Trionic on pin 14 (K22) and the signal is grounded via pin 6 (K22) in the Trionic control module.
At 100 kPa (barometric pressure) the voltage is about 1.0 V.
The main instrument unit controls the turbo pressure gauge so that its reading is proportional to the pressure in the intake manifold.
