Hello,Ihave weird problem with my bravo searching for simillar problem but i cant find it.Long story my bravo was tuned 4-5 years ago and run flawess until now.The ecu don't want to switch to closed loop.The car hasn't check engine light or error codes for lambda sensor.
I buy two new sensors,doesnt work.The sensor was tested on diffrent car working perfect.
New ECU,same thing.
I Checked the pins of the lambda plug:
pin 1 power 14v
pin 2 PWM ground working(tested with bulb)
pin 3 Ground
pin 4 signal
The signal voltage stay at 450mv constant
