97 E320 Check Engine Light/OBD Codes
Scanned the codes and got 3 codes: P0170, P0130, and P0170. Don't know why P0170 came up twice. From the research, P0170 is most likely the mass air meter, and the p0130 is the oxygen sensor.
I read some where that W210 E310 has two oxygen sensors, how do I tell which one failed?
Anybody know if the 10 year california emission warrenties on autos cover oxygen sensors.
