“With ignition switched on (engine not running) the duty cycle should be about 70% .” Here I have 50% and when moving the air sensor plate 40%.
“With the throttle half opened + the air sensor plate not deflected the duty cycle should be about 10%, and the throttle fully opened + the air sensor plate not deflected the duty cycle should be about 20%.”; this is ok on my engine.
EHA circuit is given correct values. When the engine is in closed loop , duty cycle is fluctuating at 50 %.
The car drives not bad .
So I can not figure out this faulty static duty cycle reading.
