My car has an intermittent check engine light.
It is being triggered by the shaft input speed sensor. This sensor is located between the engine and transmission, and they have to be removed from the car to replace it.
A daunting task to be certain.
I assume Cadillac has used a hall sensor to for this application. As it is an intermittent problem I am thinking that the hall sensor is getting too hot. Either due to age, or it may be close to failing.
Rather than remove the drivetrain from the car, I am thinking that if I can reduce the load on the sensor it won't get so hot.
I am thinking that placing a transistor between the sensor and the ECU will reduce the load on the sensor. Kinda like a gain stage of an amplifier. I would think that I could then reduce either voltage or current to the sensor and wouldn't get so hot.
Is my Idea sound? If not, can anybody tell me a solution which may work?
If you know what circuitry I might try, along with values it will be greatly appreciated.
Thank you.
