O2 sensor Location...
Hello all...
Just returned from a MB dealer diagnostic with the following error results: 1. Hi voltage for rear O2 sensor Code PO138- Circuit High Voltage and Switchover valve controls Recieved "Mixture too rich" fault. 2. Upshift delay- My car shifts aggressively in 1st and 2nd gear, moreso when cold. Dealer indicated that is may be Throttle actuator, whatever the hell that is.... I was informed that the O2 sensor needs replacing...Please educate me on where the O2 sensor is on a 1994 C220 and if this is a difficult process to replace. Thanks in advance.

On the exhaust. The rear O2 sensor is the one downstream of the cat.
