Oxygen Sensor Replacement
I got a OBD2 code of 0135: oxygen sensor/heater bank 1/sensor 1
I assume that this is for the upstream sensor
does anyone know the OEM or GM part number for this sensor?
This sensor sits just behind (or in)the exhaust manifold and is accessible from the top of the engine. (correct?)
Looking at rockauto I see three AC Delco candidates:
3) exhaust manifold
What's the difference?
I'm looking for the cheapest one that will get me through inspection.
Any thoughts on the Denso 234-4342?
I would appreciate any suggestions.
