I have a code 17 check engine light. I'm pretty sure that has something to do with the O2 sensor. The O2 sensor had constant voltage of .5 volts when I tested it with the car running. Also the heater wires are getting no power. Would this be fixed just by getting a new O2 sensor? Any help is appreciated. Thanks.

 

I have a 1990 300e. I got the 17 flashes from the OBD right next to the battery. I held the button for about 3 seconds and then I got the 17 red flashes. I didn't hook it up to a code reader or anything.

 

I cleared the fault and the check engine light came back on with the same code. Would you recommend getting the Bosch O2 sensor specifically for my car or get a mustang O2 sensor and then rewire so the connector fits. The mustang sensor is cheaper and would save some money. Which would you suggest?

 

Ok cool I'll for sure look into it. Thanks for all your help!
