Analogue Ground Monitor - P1243

Analogue ground monitor - P1243
The output voltages from the following sensors are checked:
- Throttle sensor 1
- Throttle sensor 2
- Accelerator pedal sensor 2
- Fuel tank pressure sensor (on USA market cars)
- Intake air temperature sensor
- Coolant temperature sensor
- Intake air temperature sensor after inter-cooler (on supercharged cars)
- Fuel rail pressure sensor
- Intake manifold pressure sensor
- Oil temperature sensor

If they all fall below a threshold value then a counter is incremented, otherwise the counter is reset to zero. If the counter reaches a calibrated value a failure judgement is made.
