"http://wiki.answers.com/Q/What_is_the_shop_labor_hours_to_replace_a_knock_sensor_on_a_infiniti_q45_1997"
The sensor is located under the intake manifold. It takes about 2 and half hours to replace the intake manifold, book time. Knock sensor is about $35 + $60-$90/hr labor. So you are talking about $300.
~$400 on OEM parts + 8 hours of labor
how much does it cost for labor to change a knock sensor in a 2002 toyota siennna van
It is behind the intake manifold on the left side of the engine. It will take almost 6 hours to replace this cheesy part ($120) and cost about $500 in labor alone.
With mucho effort, that's how. The sensor is behind the intake manifold, throttle body ect, all of which must be removed. Labor alone will be 5-6 hundred , knock sensor another 150 or so. Good luck.

The knock sensor is located UNDER the intake. You have to pull the intake off. I had a mechanic do mine. he said its best to replace both because they both corrode. (2 sensors, intake gasket, labor ($250)
labor cost to change an oxygen sensor in a 1995 toyota avalon
~$211/ sensor, 4hr labor. Better to change both since labor is still going to be the same. You may also need to change the gaskett.
