O2 sensor heater wires
The heater wires for my o2 sensor is getting no power. What could be the source of this problem? Thanks
|
At what disconnected connector did you make that observation???
|
At the connector underneath the passenger side floor mat. Heater wires get no power and the sensor wires stays constant at about .45 volts. They were not disconnected when I tested it and the car was running and warmed up.
|
It would save me loads of search time if could provide the VIN!!

0095429317
I'm pretty sure that's the part number. My car is a 1990 300E. Those connectors are located underneath the passenger side floor mat and that's where I tested the volts. |
FYI the part number(not a VIN)you provided is not for you car--that part is for a 300SE or 300SEL---be careful in what you are doing
|
Are you sure that's not the correct part? I'm pretty sure that's the same thing as the Bosch 13146 which is the oem part.
I am aware I gave a part number to you and not a VIN. Yes I know what a VIN is. It has both numbers and letters in it. From looking at the numbers you gave I assume you want the model and engine numbers though. Those numbers are 124.030 and 103.983 |
Yes I am sure the part number you provided is not for the car you think you drive---that is why most folks who offer help will request a VIN repeat a VIN not a part number to confirm!!
|
The applicable part for your VIN is 009 542 91 17---there are no revisions
|
Ok and back to the original question. Why could it be that the heater wires get no power?
