Engine sensors explained

[sam2019]

I wonder which ones are present in a BS4 and/or BS6 Hima:


00:57 Crankshaft position sensor
02:54 Camshaft position sensor
03:58 Throttle position sensor TPS
05:44 Mass air flow sensor MAF
07:39 Vane air flow meter AFM
08:44 Manifold absolute pressure sensor MAP
10:27 Oil pressure sensor
11:55 Fuel pressure sensor
12:34 Intake air temperature sensor IAT
14:09 Coolant temperature sensor
15:22 Fuel temperature sensor
16:16 Oil temperature sensor
17:24 Oxygen 02 sensor
20:18 Exhaust gas temperature sensor EGT
22:05 Nitrogen oxide sensor NOx
23:01 Knock sensor

In the Hima you get:
- Crankshaft (in the engine basement)
- TPS (on throttle body)
- MAP (on throttle body)
- IAT (on the airbox)
- ECT (mentioned in the video as the coolant temperature, but it's mounted directly on the engine barrel being an air cooled engine)
- Fuel pressure (?) probably inside the fuel pump
- O2 Sensor (on the exhaust pipe)

Fuel pressure is controlled by the releif valve inside the Pump assembly but not monitored.

I found out on the service manual that there is also an oil pressure sensor in the engine, after the pump!

I guess it’s that sensor that was shutting off your bike when you swap the radiators and there wasn’t enough oil circulating!

Yes that is the one responsible.
All good if your battery can take the drain, not likely to happen often although I am in the process of fitting a new cooler to the 500.
