What is the location of oxygen sensor for 1989 Dodge Dakota?
The 1989 Dodge Dakota oxygen sensor can be found on the top of the engine. The oxygen sensor will be on the back side of the air cleaner housing.
The 4.7L 2002 dodge durango has 4 O2 sensors. ref. Chilton's Dodge Durango/Dakota 2001-03 repair manual. page 6-19 (Oxygen sensor - general info and replacement) The upstream oxygen sensor is located before the catalytic converter. The downstream oxygen sensor is located is located after the catalytic converter.
PO136 on a 2000 to 2003 Dodge Dakota (It may be true for other year Dakotas) means "Downstream oxygen sensor circuit problem (left cylinder bank)". This is the oxygen sensor that is located just past the catalytic converter on the driver's side and measures the oxygen level after the exhaust has passed through the catalytic converter. I
