The OBDII system uses aux heater glow plug circuit short to ground a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look aux heater glow plug circuit short to ground: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression.
