Hi team,
I need your strong advice.
I have an CAT M317 wheeled excavator equipped with C4.4 ACERT engine. I’m encountering a problem which involves engine speed sensor.
As I linked up CAT ET service tooling, status flag posted “no engine speed”. As I crank the engine and monitor “no start parameter”, Injector disabled is “on” during cranking resulting to no fuel injection into the combustion chamber. I tried disconnecting the primary engine speed sensor, fuel injection occurs and engine starts. How does it happen?
As per my observation within the no start parameter during cranking, primary and secondary engine speed sensor was detected.
Given the fact that the sensors are newly replaced.
Kindly help me within this matter.
Thankyou!
