What range of KΩ ms 1 and 2 can read?

Post by ManosVit »

Hi from Greece .

I want to ask whats the range of ΚΩ that MS1, MS2, can read from the sensors. E.X My car uses a Magneti marelli injection system wich its sensors have 2 KΩ resistance the question is can i keep the OEM sensors such as VR.TPS.MAP sensor ? And the other question is what can i do to avoid chanching the ignition coils wich is coil per plug ?

Manos Looking forward for your reply.

P.S Sorry for my bad english. :oops:

The MS is looking for voltage on the TPS, so it doesn't really care about what its ohm reading is there, as long as it's high enough to avoid drawing excessive current. If it's 1K or more, you're good to go.

The VR sensor is also voltage based. It can trigger off less than 0.01 volts. And the MS has a MAP sensor built into the case.
