Services Performed
- Engine codes: P0137 HO2S circuit low voltage sensor 2. P2270 HO2S lean sensor 2. When the vehicle is started, the down stream O2 is reading ok. On the road test, once the exhaust gets hot, the voltage drops that the O2 puts out drops to 0 volts, it shouldn't do that. Need to start with a down stream O2 sensor. The exhaust rattles when warming up. It goes away when it's hot. It sounds like the catalytic converter internals have broken away. Tried peering in with a bore scope but can't determine if the internals broke loose. Exhaust will have to come down to know for sure.
- Coolant leak, coolant on bottom of radiator. Engine oil leak, possibly water pump access cover. Left front inner brake pad looks very low compared to others (did not remove wheel, just peaked in with mirror).
- New O2 sensor reads from 655-885 milli-volts on the road test vs the 0 it was reading before.
