Helping friend with a Dodge Ram 1500 1998 5.2L.
We replaced the rear 02 sensor because a wire burnt and went to ground. We cleared codes, truck ran fine for 2 days CEL came on again, with code p0135.
Book says 02 Sensor heater circuit malfunction cyl bank #1 Sensor #1.
Is this the 02 Sensor closest to the engine? We already changed the 02 Sensor furthest from the engine.
Exhaust smells like the engine is running rich.
TIA
