hi i have this fiat grande punto 1.4 tjet from 2008
i just bougth the car a coupel a months ago. when i put the obd tester on the car, i get a error on the heater circuit. and what could see the previus owner had change the o2 sensor. but it was a uogrianl one. so i changedit with a bosch one but i still get the same problem.
when i mesure the 2 white wire on the o2 sensor i only get 8volt output when the o2 sensor i pluged off. and when i put load on i its drob to abut 0. i have chek the wires its not the wire. its the same at the output of the ecu. my question is can it be a fuse. i have try to look at it with a circiut tester but not put out look and put back.
my o2 sensor newer gets heated so it cant messure a/f ratio
sry for my bad english
