Hey guys,
I've been struggling with multiple problems with my 2000 306 1.4 petrol. I'm an amateur mechanic, and wiring is certainly not my specialty. Problems ranged from a faulty wiper motor, faulty ventilation motor, radiator fans turning off and on irregularly... Also, problems with running while cold (stalling!), irregular idle especially cold, but also moving between like 600-1400 when it returns to idle... I'm starting to think it's to much issues to easily solve, but I still like the car and it still looks pretty good for its age...
Now, after acquiring a multimeter to test some sensors, I found out the sensors itself seem fine, but voltage to different sensors is zero/low? Including green and brown coolant temp sensors, which could explain cold start and fan issues? Also idle control valve(is that the right term??), map sensor.. Haven't tested every sensor, but others do have stable 5v, the blue temp sensor, tps.. Could there be a common point in the harness broken or something? Ground issue somewhere? Something I'm missing?? I did check grounds just below the battery but don't no where to find the rest?
Any tips.....?
