Couple days ago check engine appeared for the first time, I read the codes using Autel AP200 and got:
P013504 -an electrical fault exists in the heater for oxygen sensor 1 (cylinder bank 1). An internal fault exists.
I've done lots of reading and in the meantime ordered another sensor (bosh). Based on the reading I've figured out it's 5 wire wideband with white and grey cables being for the heater. So, picked up multimeter and checked resistance, roughly 3 ohms. I wasn't sure if it's good or bad so when the new lambda sensor arrived i checked it and it also gives 3 ohms.
I've replaced the sensor with the new one and as you can guess it didn't solve the problem. I've tried to clear the codes but get error message that they can't be cleared.
Not sure what to do next, if there is an easy way to check what else could be wrong without having some sensor specific tool. I've checked fuses and all those under bonnet seem ok
